中国城乡收入差距变动的成因分析:兼论“倒U”假说的适用性

The income gap between urban and rural has presented a basic trend that reduces firstly and enlarges subsequently since 1978, and this trend differs from the conclusion of Kuznets “inverted-U” hypothesis. Many explanations have been given to this changing character and a lot of disputes exist. This paper establishes a multiple analytic framework which is based on a panel data, and the positive research reveals that “inverted-U” hypothesis didn’t abate in China, whether economic opening or urbanization have both thrown “inverted-U” effects on the alternation of Chinese income gap between urban and rural, but these effects have been influenced heavily by the regional administration system and developmental patterns, institutional reform, and policies aiming at overtaking. To reduce Chinese income gap between urban and rural, we must improve the regional administration system and developmental patterns, promote the market reform further, and increase the policy support in agriculture.
