Visualizing the knowledge domain of anti-poverty research between 2011 and 2020: a bibliometric analysi in CiteSpace

ABSTRACT: The elimination of poverty and hunger in all its forms and dimensions is one of the key objective of global sustainable development (GSD). This paper analyzed the characteristics of literature release, research progress and frontier trends in the field of anti-poverty in the past ten years by means of bibliometrics, and information visualization. Using CiteSpace to analyze the literature on anti-poverty in the core journals of Web of Science and Scopus (W&S), and China National Knowledge Infrastructure (CNKI). The results showed that:(1) The heat of anti-poverty research is on the rise in both W&S and CNKI, the growth rate of Chinese literature published is significantly higher than that of English literature after 2015, but the international influence is not enough. (2) Researchers and institutions in W&S are more independent than in CNKI. The Chinese research team is more stable and larger, but it needs to be further strengthened in cross-institutional and interdisciplinary research. (3)The research content in W&S mainly focuses on influencing factors and poverty reduction mechanisms, ecosystem services, maternal health and sustainable development. According to the China National Knowledge Infrastructure (CNKI), China paid more attention to concrete ways to reduce poverty, and after completing the fight against absolute poverty by 2020, China will pay more attention to reducing relative poverty and solve multi-dimensional poverty problems by improving the security of medical care, education and housing conditions.


INTRODUCTION
With the adoption and formal launch of the 2030 agenda for sustainable development at the United Nations General Assembly, the elimination of poverty in all its forms throughout the world has become the first objective to advance sustainable development.In recent years; although, great progress has been made in the fight against poverty all over the world, the progress is uneven in different regions.Serious poverty and health problems still exist in some regions, such as central Africa, South Asia RESUMO: A eliminação da pobreza e da fome em todas as suas formas e dimensões é um dos principais objetivos do desenvolvimento sustentável global (GSD).Este artigo analisa as características da divulgação da literatura, o progresso da pesquisa e as tendências de fronteira no campo do combate à pobreza nos últimos dez anos por meio de bibliometria e visualização de informações.Uso do CiteSpace para analisar a literatura sobre combate à pobreza nas principais revistas da Web of Science e Scopus (W&S) e da China National Knowledge Infrastructure (CNKI).Os resultados mostram que: (1) O calor da pesquisa anti-pobreza está aumentando tanto na W&S quanto na CNKI, a taxa de crescimento da literatura chinesa publicada é significativamente maior do que a da literatura inglesa após 2015, mas a influência internacional não é suficiente; (2) Pesquisadores e instituições em W&S são mais independentes do que na CNKI; a equipe de pesquisa chinesa é mais estável e maior, mas precisa ser fortalecida ainda mais na pesquisa interinstitucional e interdisciplinar; (3) O conteúdo da pesquisa em W&S concentra-se principalmente nos fatores que influenciam e nos mecanismos de redução da pobreza, serviços ecossistêmicos, saúde materna e desenvolvimento sustentável.De acordo com a China National Knowledge Infrastructure (CNKI), a China prestou mais atenção a formas concretas de reduzir a pobreza e, após completar a luta contra a pobreza absoluta até 2020, a China prestará mais atenção à redução da pobreza relativa e resolverá os problemas de pobreza multidimensional em melhorar a segurança dos cuidados médicos, educação e condições de habitação.Palavras-chave: bibliometria, sistema de conhecimento, combate à pobreza, hotspots de pesquisa, CiteSpace.

Ciência Rural, v.53, n.2, 2023.Yin et al. and many small island countries.The increasingly uncertain world politics and economy, the conflict between industrial development and environmental issues have brought new challenges to global poverty management and aroused the international community's thinking on world poverty reduction and development.According to the World Bank, there were 632 million peoples have been living in absolute poverty worldwide in 2019, with a poverty rate of 8.2 percent.As a result of the new crown virus pandemic, the world probably have added 40 to 60 million people to the poverty line by the end of 2020, it will be the first global increase in poverty since 1998.The year 2020 is the end of China's strategy for overcoming poverty.China will also face a series of problems such as preventing social risks, adjusting policies and changing national strategies.
looking back on the past few decades, governments and international organizations have made anti-poverty a focus of their attention and a long-term challenge.They have taken a series of measures to promote the global anti-poverty work and accumulated a lot of successful policy and practical experience.China has also made anti-poverty a major national strategy and has achieved remarkable results in the past decade, making a significant contribution to global anti-poverty efforts (LIU et al., 2020).During this period, anti-poverty issues have also received great attention from research institutions and scholars in various countries.The research results have played an important role in the process of public policy designing and government decision-making.The impact of academic research on politics has gradually become more comprehensive, direct and powerful.Literature review is considered to be an effective way to deeply understand the research field (ZUO & ZHAO, 2014), and a systematic review of the existing literature will help scholars and governments to seek deeper solutions to the problem of anti-poverty.
Since Web of Science (WoS) is an important database of global academic resources, containing the most influential core academic journals in various fields of research, it has a relatively high authority for scholars in most countries.Scopus, currently the largest abstract and index database in the world, contains a larger number of journals and papers, is an important supplement to WoS.Although, many papers by Chinese are included in WOS and Scopus (W&S), CNKI (the largest database of academic documents in China) still contains a large number of excellent research and important discussions in the field of anti-poverty.The main reason may be due to the limited English writing skills of many Chinese top scholars and the call of the Chinese government to publish important papers in domestic journals since 2016.Therefore, the combination of the three can comprehensively reflect the research situation in the field of anti-poverty in Chinese and English literature.
In view of this, the current study uses CiteSpace (JIE & CHEN, 2016) as a bibliometric tool to carry out quantitative statistical analysis and qualitative description of the literature of anti-poverty research in the past ten years.It provides a comparative analysis of publishing trends, cooperative networks, knowledge base, and research hotspots based on W&S and CNKI databases.With a sample of 7081 English studies in W&S and 5635 Chinese studies in CNKI, this study explored the research status, development course, and potential trends of anti-poverty research.It presents the knowledge structure of the global anti-poverty field from 2011 to 2020, which can be used as a useful reference for other scholars, and provide experience for the government to promote the sustainable development of urban and rural areas.

Data source and search strategy
WoS's core database is considered to be an appropriate source of data for scientometric analysis (ARCHAMBAULT et al., 2009), which can effectively guarantee the authority of data selection (yAo et al., 2014).The retrieval formula is as follows: TS = (poverty alleviation) oR (TS = anti-poverty) oR (TS = poverty reduction), literature type is research article, the time span is set from 2011 to 2020, the source journal is set to Social Sciences Citation Index (SSCI), and 3094 records were retrieved.To ensure the comprehensiveness of the data, we searched the Scopus database again with the same retrieval strategy as above, and obtained 9513 documents.In order to make the analysis more accurate, we adjusted and merged the two data sets, removing duplicate data, advertisements, letters and other extraneous material, and ended up with 7081 pieces of information.
CNKI was used to search studies in Chinese, the search terms were "poverty alleviation" or "anti-poverty" or "poverty relief", the time span is also set from 2011 to 2020, the source of the journal is only set as Chinese Social Sciences Citation Index (CSSCI), and 5921 studies were obtained.In the process of data processing, we eliminated advertisements, book reviews, topic guides and biographies, and finally got 5635 records.

Methods and tools
Visual analysis is an important means to reveal the internal characteristics and laws of information.It can visualize a large amount of data and information so as to improve people's discovery, understanding, analysis and formation of the whole concept of things.Knowledge map is an important branch of visualization research.It integrates the theories and methods of applied mathematics, graphics, information science, and metrology.It can systematically describe the core structure, development history, frontier fields and the whole knowledge structure of a certain research field (ZENG et al., 2019;SHI & LIU, 2019).
CiteSpace is a knowledge mapping software developed by Dr. Chaomei Chen of the Drexel University in the United States, which has the characteristics of multiple, time-sharing and dynamic (CHEN, 2006).It can promote analytical reasoning through data mining of literature and visual interaction, thus effectively helping scholars to better understand the field of research they are engaged in it (ZHU & HUA, 2017).In this study, CiteSpace was used to generate the author collaboration network, institution collaboration network, subject categories cooccurrence network, burst detection, and so on.It is a systematic demonstration of the structural relationships between various knowledge units in academic research and the evolution path of subject knowledge (YIN & CHOWDHURY, 2001;DIEGO et al., 2019).

Quantitative analysis of the studies on anti-poverty
The annual distribution of publications can reflect the development progress, research hotspots, and the changing trend of research on anti-poverty.This study makes a preliminary statistical analysis of the publication of Chinese and English literature (Figure 1).It shows that although there are some differences in the number of anti-poverty studies issued in W&S and CNKI, they all show an upward trend on the whole.During the period 2011-2015, the number of literature in W&S was slightly higher than that in CNKI, but after 2015, the number of literature in CNKI showed a blowout growth trend, and its growth range were much higher than that in W&S, and reached a peak of 1259 in 2020.The possible reason is that General Secretary Xi Jinping, in response to various practical problems in China's anti-poverty campaign, put forward the concept of targeted poverty alleviation at the end of 2013, which promoted a major transformation of China's poverty alleviation strategy.The promulgation of important policy documents such as The Decision of the CPC Central Committee and the State Council on Winning the Battle against Poverty in 2015 has injected vigorous momentum into the academic circles.
The country collaboration network can reflect the degree of attention and cooperation of different countries on anti-poverty issues.In this Ciência Rural, v.53, n.2, 2023.
Yin et al.
study, visualization analysis was conducted with the software CiteSpace (Figure 2), by setting the Node Types to "country", setting the time slice to one year.
In figure 2, the node represents each country, and the number of annual studies is displayed with different color and size rings.The connection represents the cooperative relationship of each country (CHEN et al., 2012).obviously, the cooperation network between countries has been initially formed, and academic research mainly revolves around the United States.
However, the connection between the nodes is thin, indicating that the cooperation between countries is not strong enough.
Through the data analysis of literature quantity and centrality, we can understand the contribution and influence of each countries (Table 1).For the past ten years, W&S database contains 2598 articles from American scholars, accounting for 36.68% of the total literature, and the United States ranks first in the number of articles published, followed by United Kingdom with 1256 articles in the second place.China, Australia, and Canada also have a relatively large number of papers included in the W&S.Centrality is the indicator of determining the importance of a node in the network.The higher the centrality, the more important the node is in the network.In terms of network centrality, the United States, Germany, Netherlands, the United Kingdom, Australia, and Canada have higher scores, indicating that they play important roles in the global research network in the field of anti-poverty.Although, China has made a great contribution to the anti-poverty practice in the world and has published a large number of papers in English, its centrality scores only reach 0.05, indicating that its international influence in academic research is not strong enough.
The number of papers published by research institutions and the cooperation network can reflect their research capacity and social influence.Set the Node Types to "Institution", the time slice to one year, select the top 50 institutions in each stage, then run CireSpace get the pictures of cooperative network of research institutions (Figure 3).Each circle in the picture corresponds to a research institution.The line indicated that there is a cooperative relationship between the institutions, and the line thickness represents the degree of cooperation.According to the analysis of W&S database (Figure 3a), the World Bank, the International Food Policy Research Institute, the Chinese Academy of Sciences and oxford University have contributed the most to the publication of English literature in the past 10 years.The overall connectivity of the network map is strong, indicating that the cooperation between institutions is close.Meanwhile, within the CNKI data (Figure 3b), we found that China Agricultural University, Renmin University of China, Central South University for Nationalities, Wuhan University and Central China Normal University are high-yielding institutions in Chinese publications.
The number of papers published by the authors and the collaboration network revealed their contribution to this field and co-operatives relationship during this period, and the top 10 authors are listed (Table 2)

Important literature on anti-poverty
CiteSpace can provide scientific and intuitive citations information, so that researchers can easily identify the foundation literature and important studies at the forefront of the subject.For the W&S data, we conduct the reference co-citation analysis, reflecting the situation that two (or multiple) articles are cited by other articles at the same time, to show the relationship between the studies and the common research direction.The centrality of each article represents the degree of importance in the network (PAN & HE, 2018).By setting time slice = 1 year, top N = 30, using the MST (minimum scheduling tree) method for network pruning, we get the co-citation knowledge map of the English literature (Figure 4).Due to the limitation of data structure, this study focuses on the analysis of highly-cited documents for CNKI data (Table 3).The landmark study in this field is China's Targeted Poverty Alleviation, published by WANG SANGUI & GUO ZIHAO (2015) in Guizhou Social Sciences in 2015, which was cited 1730 times.They believe that targeted poverty alleviation is the main way of poverty alleviation in rural areas in the future, and it is a challenging task to identify the poor accurately and take the right measures to support them.The followed is The Difficulties, Countermeasures and Path Choice of Targeted Poverty Alleviation, which was published by DENG WEIJIE (2014) and has   innovation, policy making and working mechanism of poverty alleviation in China.

Research hotspots
Key words are one of the important parts of the article that express the core content of the research.The frequency analysis of key words is helpful to understand the research hotspots in the field of anti-poverty (REN et al., 2016).According to the statistical analysis of keywords, we listed the top 15 keywords of co-occurrence frequency, and calculated the centrality by CiteSpace (Table 4).The degree of centrality indicates the importance of the keywords (CHENG et al., 2018).In W&S, The keyword with the most frequent occurrence is poverty, which occurs 2104 times with a centrality of 0.27.This is probably due to the continuous discussion of the nature of poverty among scholars.The definition, measurement and manifestation of poverty have always been the focus of western scholars' attention, and their studies have formed the research foundation of anti-poverty field.Other keywords with high frequency and high centrality are as follows: poverty alleviation (1664, 0.14) , impact (1343, 0.18), women (1095, 0.25), policy (906, 0.19), inequality (756, 0.06), livelihood (674, 0.15), management (418, 0.13).These different keywords present a rich perspective on anti-poverty research in the English literature.
In CNKI, targeted poverty alleviation was the most frequent keyword (1,410 times), with the highest cardiac activity (0.24).It can be seen that how to accurately identify the poor population and provide accurate support measures is the most concerned issue of the Chinese government and scholars.The following keywords also reflect the direction of China's efforts in poverty reduction: development-orientated poverty reduction (307, 0.18), ethnic minority areas (267, 0.2), pro-poor tourism (226, 0.16), poverty governance (220, 0.11), and multidimensional poverty (217, 0.11).
From the distribution of keywords, we can see that in the English literature, scholars pay more attention to the influencing factors and mechanisms of poverty, They have made more rich and in-depth theoretical discussions in the field of anti-poverty, and have conducted detailed classified studies on women, children, equity, ecological services and other aspects.However, In Chinese journals, scholars have done a lot of research on the methods, models and efficiency evaluation of poverty alleviation.They paid more attention to ethnic minority areas and separately demonstrated the importance of regional development, pro-poor tourism, agricultural development, public culture and microfinance for poverty reduction.
In the process of keyword co-occurrence, nodes with higher co-occurrence frequency are closely related, and their clustering can reflect the same topic (WEI et al., 2019).Using the default algorithm llR (log-likelihood Ratio) testing and MST (Minimum Scheduling Tree) pruning in CiteSpace, setting Node Types=keywords, Time Slice=1 year, Top N per slice=50, the cluster labels are extracted in this study.In W&S, the network had a modularity score of 0.5142 (>0.3), and the silhouette score was 0.6275 (>0.5), it shows that the clusters were well structured (CHEN, 2004).The results of cluster analysis are displayed in figure 5.
There are seven clusters, and each polygon representing a subdivision of the field of anti-poverty research, and they are both cross-related and divergent.The details of each cluster are discussed below.
The largest cluster (#0 influence factor) includes 67 articles and the silhouette score is 0.608.In this theme, the impact factors of poverty have been fully discussed from the aspects of economic growth, globalization shock, migration, exchange rate, and so on, and extensive research on urbanization, reform and income equity has been carried out in the past two years (REHAM et al., 2018;KHAN et al., 2019).In 2020, the outbreak of CoVID-19 attracted academic attention and caused heated discussion on a range of issues related to the global public health emergency and poverty (AKSEER N, 2020; BRAUER M, 2020).
The second cluster (#1 stress reduction) includes 52 articles, its silhouette score is 0.572.In this field, scholars have explored the interrelationship between poverty, stress, health and other issues.For example, HU J (2014) reported that patients living in high-poverty neighborhoods were 24 percent more likely to be readmitted to the hospital than others, and that individuals without social support performed similarly.
COMMODORE-MENSAH (2016) noted that, the level of cardiometabolic risk (CMR) burden is closely related to socioeconomic status, Medicare status, geographical location and other factors.African Americans are 30% more likely to die from cardiovascular disease than whites.HJELM l (2017) believed that poverty reduction programs can reduce psychological stress, where food security is significantly related to stress perception, but cash transfer does not significantly reduce perceived stress.
The third cluster is #2 ecosystem services, which contains 49 articles and the silhouette score is 0.701.Most of the studies focused on issues such as poverty management, corporate social responsibility, biodiversity, ecologically sustainable development, and livelihoods.In recent years, discussions on the development of fisheries, land use, and environmental services have also increased (DAW et al., 2011;CAPPS et al., 2016).For example, in a study of Rwanda's green growth policy, BANERJEE et al.( 2020) reported that the combination of crop fertilization and afforestation could better balance important ecosystem services and support economic development.JIAo et al. ( 2019) through a case study of the Greater Serengeti-Mara Ecosystem and its surrounding local communities in Tanzania and Kenya, found that the poorest people are highly dependent on environmental income, and that the degradation of protected area habitats will adversely affect income and may further reduce the welfare of the poorest families.The cluster #3 women includes 33 articles, the gender gap in anti-poverty efforts, especially in the areas of women's rights, employment and consumption, maternal health, has been fully discussed.After 2016, the issues of multi-dimensional poverty and entrepreneurial ability have attracted the attention of scholars (ANToNIADES et al., 2019).MEINZEN-DICK et al. (2019) reviewed the literature on women's land rights (WlR) and poverty reduction, he believed that WlR could reduce poverty and improve the well-being of women and their families in rural areas.FINlAy et al. (2018) reported that the improvement of reproductive health leads to the improvement of women's economic empowerment, and that women's working ability, education level and labor force participation rate have increased significantly, which is an important way for women and families to escape the poverty trap.
From the fifth cluster (#4 participation), we can see that government's participation in poverty reduction plays an important role in poverty alleviation (especially for children) through the formulation of strategies and policy design (GERRITSEN et al., 2019;WEATHERSPOON et al., 2019).RICHTER et al.( 2018) believe that improving children's school readiness through optimal policies is critical to achieving social transformation in South Africa.Improving the quality of education, parental and family participation, home-based learning and preschool preparation are keys to reducing poverty and inequality.
The last two clusters are "#5 food security" and "#6 property right".SECK (2012) stressed that fears about global food security have led to soaring food prices and social unrest, resulting in poverty for hundreds of millions of people, and the rice sector should increase the rice yield ceiling through variety development and improved production methods.OZTURK (2017) believes that the poor in less developing countries are mainly affected by climate change, food security challenges, lack of water and inadequate power supply.He argued that agricultural sustainability is the prerequisite for reducing food-energy-water poverty.Researchers believe that by defining property rights, developing agriculture and tourism, rural economic growth can be promoted and rural livelihood problems can be effectively solved (GARZA-RODRIGUEZ, 2019;WANG et al., 2019).
From the overall content of the Chinese journal and the logic between the research hotspots, it can be seen that China has always adhered to the development oriented poverty reduction policy and made outstanding achievements in economic development, which has also inspired the aspiration of the poor people to get rid of poverty and become rich.After 2011, China has incorporated poverty control into the strategic goal of national governance, and implemented special government governance to mobilize all members of the party and government institutions, enterprises, the army, schools, social organizations and groups to participate.By the accurate identification of the poor population and the establishment of the archives of the poor households, and relying on the political and administrative advantages of the national system, the financial reserves of the central and local governments can be used to help the poor households effectively.By developing competitive industries, finding jobs elsewhere, relocating the poor, improving education, providing better healthcare, and guaranteeing basic living standard for people unable to work, the rural poor population has been greatly reduced.
According to the distribution of hot topics between Chinese and English journals in the past ten years, there are great differences in both hot keywords and hot clusters.In English literature, more attention is paid to the innovation and research of anti-poverty theory itself, and more keen to conduct in-depth discussion on the mechanism and principle of the problem.This may be related to the normative research paradigm and thinking mode formed by western scholars in the field of social science for a long time.In Chinese journals, scholars pay more attention to the practical methods and effect evaluation of solving the poverty problem at this stage.It may be due to the very limited time of the Chinese government's commitment to address the poverty problem of all the national population by the end of 2020.What is undeniable is that the development of global antipoverty theories has provided a good reference and guidance for China's poverty reduction work.For example, China has made full use of the feasible capacity theory and the multidimensional poverty theory to set the minimum security standards for the poor in terms of food, clothing, education, medical care, housing and so on.China has also borrowed from the theory of ecosystem service in solving the poverty problem in high-altitude and remote rural areas, and has actively explored the ecological value conversion model in these areas.At the same time, China's successful poverty reduction practice has also become an important part of international poverty reduction and development, and its model has strong Chinese characteristics, especially in terms of government leadership and the participation of the whole people (CHEN, 2018;LI et al., 2016).In recent targeted poverty alleviation strategies, the participation of governments, enterprises, research institutions and common people have all played an important role, and the model and implementation plan of poverty reduction can provide reference to other countries in the world.

CONCLUSION
This study conducted a scientometric review of the literature published between 2011 and 2020 in W&S and CNKI, and uses CiteSpace software to visualize the research progress, cooperation network, research hotspots, and frontiers in the field of anti-poverty.The conclusions are as follows: Anti-poverty has become a hot issue in the world.In the past decade, the popularity of relevant research in W&S and CNKI has increased year by year, and the exponential growth of Chinese literature since 2015 has played a positive role in promoting the improvement of China's poverty alleviation policy.The United States and the United Kingdom have absolute advantages in the number and influence of English literature publication; although, China ranks third in quantity, the international influence still needs to be improved.
There is a certain cooperative relationship in the field of anti-poverty research in W&S and CNKI.liu y( Chinese Academy of Sciences), Shackleton CM (Rhodes University,), Abdoulaye T (International Institute of Tropical Agriculture) and Handa S (United Nations International Children's Emergency Fund) have a higher number of papers published, and prefer to complete the research independently, and their cooperation team is small.The cooperative team of Chinese scholars is more stable and larger, and has formed a network of author teams and research institutions with Wang Sangui (Renmin University of China), Zuo Ting (China Agricultural University), Zhang Qi (Beijing Normal University) as the core.Since anti-poverty has become a systematic project, it is necessary to further strengthen cross-institutional and interdisciplinary research in the future.
Based on the analysis of W&S data, there are seven landmark studies in this field that propose new research frameworks and concepts on antipoverty emphasizing that agricultural development, pro-poor migration and linking ecosystem services to components of human well-being can effectively improve the lives of the rural poor.The topic of landmark studies in CNKI is mainly focused on targeted poverty alleviation, because a large number of poverty alleviation policies issued by the state every year stimulate the enthusiasm of Chinese scholars.Then, through keyword clustering analysis, it is reported that there are great differences in research emphasis in W&S and CNKI.The research topics of English literature can be divided into 7 clusters, while Chinese literature can be divided into 9 categories.
The comparative analysis of W&S and CNKI data showed that the evolution trend of research hot spots from 2011 to 2020 is not the same.In general, the common frontier topics of scholars from various countries in the future may involve issues such as poverty relief effort through consumption, innovation, health promotion of children and women, food security, green growth and sustainable development, etc.

. In W&S, Liu Y from Chinese Academy of Sciences ranks first with 21 papers published, followed by Shackleton CM (Rhodes University, 17 papers), Abdoulaye T (International Institute of Tropical Agriculture, 15 papers) and Handa S (United Nations International Children's Emergency Fund, 14 papers).They are more inclined to conduct independent research and have not formed a large-scale research team.In the Chinese literature, Wang Sangui from Renmin University of China has published 39 papers and is the most published scholar so far.He has formed a stable network of cooperative relations with Yin Haodong (Development Research Center of the State Council), Zeng Xiaoxi (Renmin The results showed that, Designing payments for environmental services in theory and practice: An overview of the issues, published in Ecological Economics by Engel S in 2008, has the highest cocitation intensity (128) and high centrality (0.6).ENGEl S (2008) made a detailed analysis of the definition, operational mechanism and policy design of environmental services (PES) payments.He argued that PES, as a mechanism to translate external, nonmarket values of the environment into real financial incentives for local actors to provide environmental services, is more attractive to poor and landowners in remote areas.on the basis of the above, DAW T (2011) applied the concept of environmental services to poverty alleviation and discussed the classification and poverty reduction mechanisms for environmental services from the perspective of human well-being.FISHER (2014) proposed Ecosystem services and poverty alleviation (ESPA) conceptual framework, which serves as the basis for multidisciplinary and policy-relevant research.The studies by ALKIRE S (2007), SCHILCHER D (2007), LONDON T (2010) and FISZBEIN A (2009) also with centrality values greater than 0.25 and them all have high co-citation intensity.These scholars promoted the development of multidimensional poverty theory and measurement methods, and emphasized that the lives of the rural poor can be effectively improved by creating common value with agribusiness, advancing agricultural development, developing the pro-poor tourism industry, and linking ecosystem services to components of human well-being.These important studies constitute the knowledge base of anti-poverty research.
