摘要
将城乡收入差距纳入到贸易开放与经济增长关系的分析框架中,通过中国1987-2013年省际面板数据,采用系统GMM方法对贸易开放、城乡收入差距与经济增长的关系进行了实证检验。研究发现,贸易开放与经济增长之间表现为倒U型曲线关系,其拐点值为1.223;现阶段城乡收入差距对经济增长具有显著的正效应,城乡收入差距对经济增长的边际效应不仅与贸易开放有关,而且还与贸易开放和城乡收入差距的相互作用有关;贸易开放与城乡收入差距之间是互补关系还是替代关系取决于城乡收入差距是否在临界值范围内,并计算出此临界值为2.597。研究结果对当前省际间缩小城乡居民收入差距和加快构建开放型经济新体制过程中应该实施差别化的政策具有一定的启示意义。
Adding the income gap on the framework for take an empirical test on the inner relationship among trade System GMM method based on Chinese provincial dynamic the analysis of trade openness and economic growth ,we openness, income gap and economic growth panel data from 1987 to 2013. The results by using the showed that it exits the inverted u - shaped relation between the trade openness and economic growth, and calculate its inflec- tions point value of 1. 2231 Income gap on economic growth has a significant positive effect at the current stage. When we discuss the marginal effect of income gap on economics growth if associating trade openness and income gap, the marginal effect is not only related to the size of trade openness, but also is related to the interactions be- tween trade openness and income gap, and the relations that they are complementary or alternative depend on the threshold of income gap, also we calculate the threshold value of 2. 597. The results have some enlightenment on different policy to narrow the income gap between urban and rural residents and accelerate the construction of a new system of open economy.
