【Abstract】 This paper studies the impact of international trade on urban-rural income disparity in China. Using cross-province panel data of China 【1992-2003】, we investigate the effects of international trade on employed income and total income distribution. In addition, we check whether these effects change regionally. The results show that trade significantly increases urban-rural total income disparity in the eastern coastal region but seldom works in other regions. Moreover, trade has no significant effect on employed income disparity. 【概要】本論文は貿易開放が中国の都市・農村間の格差にどのような影響を与えるかと分析した。中国の省別パネルデータ (1992-2003)を用いて実証分析した結果, 国際貿易は東部沿海地域の都市・農村間の総所得格差の拡大に正の影響を与えるが, 内陸部の都市・農村間の所得格差に有意な影響を与えない。さらに, 国際貿易は都市・農村間の給与所得格差に影響を与えないことが明らかになった。

Using data from a rural household survey in China, this paper explores the link between employment choice (nonworking, local farm work, local nonfarm work and migratory work) and migrant earnings. We find significant self-selection in migration. Youths, men, better-educated individuals and those in good health are more likely to migrate. In terms of unobserved characteristics, we find positive selection in migration to be related to the alternatives of not working and local farm work, and negative selection to be related to local nonfarm work. Controlling for self-selection, the wage returns to gender (male), education and health are lower than those obtained from OLS, and the returns to experience are higher. More importantly, we find different self-selection between individuals who have moved as pioneers and migrants from households in which other members have already migrated.
