This paper studies the empirical relationship among factor endowment, trade openness and individual income distribution. Using panel data, we show that factor endowment characters, to some extent, explains income gap in China. First, land and Capital intensive provinces have a more equal income distribution while human capital and labor-intensive provinces have a less equal income distribution. Second, Trade openness has a significant effect on China's income distribution; the interaction between a special endowment and openness has different effect on income distribution; we also show that FDI, economy development, unemployment and reform have considerable negative effect on income distribution. Our results are robust to various kinds of test.
