Trade and Rural-Urban Income Inequality： Evidence from China

Using the provincial panel data from 1978 to 2007, this paper makes an empirical analysis of the relationship between international trade and rural-urban income inequality in China. The results show that international trade has a fundamental impact on rural-urban income inequality. For the whole country, the development of international trade from 1978 to 2007 enlarged the rural-urban income gap. During the three different periods （defined in section 3.3）, the impact was also noticeable in terms of extent, direction and significance respectively at the national and regional levels. During the three periods, the relationship has an inverted ＂U＂ shape for China as a whole, central China and western China, but for eastern China the relationship has a ＂U＂ shape. At the same time, exports and imports have different influences on the rural-urban income gap in China, the influences were also different across regions; and the imports has had a more significant influence on these regions than exports has had.

中国城乡收入差距对财产性犯罪率的非线性效应

寻求中国城乡收入差距对财产性犯罪率产生非线性影响的经验证据对进入经济新常态的中国收入分配格局有着十分重要的实践意义。比起二者之间的线性影响,分析非线性效应能够更好地揭示中国转型期复杂的经济社会因素在城乡收入差距对财产性犯罪率产生影响的过程中所起到的关键作用。本文使用中国1981-2012年的数据,运用非线性STR模型对此问题开展经验研究,结果表明中国城乡收入差距是财产性犯罪率变化的单向Granger原因,两者存在的非线性的非对称效应表现出了阶段性的变化特征。我们将其分为四个阶段,包括1987年以前的平衡I期、1987-1991年的迁移I期、1991-1997年的平衡II期和1997-2012年的迁移II期。
