Efeito das capitais de subsistência na desigualdade de renda entre as famílias rurais: evidências da China

Yang, Fan; Jiang, Yao; Zeng, Weizhong

RESUMO:

Utilizamos os dados da Pesquisa de Dinâmica da Força de Trabalho da China de 2014 para examinar os efeitos dos capitais de subsistência, que incluem capitais natural, material, humano, financeiro e social sobre a renda total da família, renda per capita, renda agrícola, renda salarial, renda operacional e desigualdade de renda da propriedade entre as famílias rurais da China. Os resultados mostraram que diferentes tipos de capitais de subsistência têm efeitos diferentes sobre os diferentes tipos de renda das famílias rurais. Especificamente, (1) embora a área de terra cultivada reduza a desigualdade de renda agrícola, aumenta a desigualdade de renda per capita. (2) A área florestal aumenta a desigualdade de renda per capita e a desigualdade total de renda familiar. (3) A variável trator reduz a desigualdade na renda agrícola e na renda familiar total. (4) Embora reduza a desigualdade de renda da propriedade, a variável educação aumenta a desigualdade de renda salarial, a desigualdade de renda per capita e a desigualdade total de renda familiar. (5) A variável contábil reduz a desigualdade de renda da propriedade. (6) A variável empréstimo aumenta a desigualdade na renda agrícola. (7) A variável partidária reduz a desigualdade de renda agrícola. (8) Embora a variável internet aumente a desigualdade de renda agrícola e a desigualdade de renda da propriedade, reduz a desigualdade de renda salarial, a desigualdade de renda operacional, a renda per capita e a desigualdade total de renda familiar.

Palavras-chave:
