摘　　要：为找出影响中国地区经济发展差距的主要原因,加快实现经济平衡发展,首先,通过界定出关键变量市场一体化的研究范围,对细分后的内、外部市场一体化水平进行测度;其次,通过构建动态面板模型,并运用系统广义矩估计GMM方法,有针对性地论证中国地区市场一体化对区域经济发展差距的影响;最后,基于市场一体化的研究视角探索出一些缩小地区发展差距的政策建议。实证结果显示,内部市场一体化对区域经济不均衡增长的作用整体存在着非线性影响;而外部市场一体化进程明显快于内部市场一体化进程,并且不同地区因经济政策的实施力度不同,相继出现了不同阶段的经济发展态势;同时,由于全国市场一体化的演变进程处于不同的发展阶段,因而内、外部市场一体化的交互项对各区域经济协调发展的作用存在差异,即东部和中部地区发挥了替代作用,且东部地区效果更明显;而西部地区发挥了互补作用。In order to find out the main reasons that affect the regional economic development gap in China,accelerate the realization of balanced economic development,firstly,by defining the research scope of market integration of key variables,the level of internal market integration and external market integration after segmentation was measured.Secondly,by constructing the dynamic panel model and using the generalized moment estimation GMM method,the impact of China’s regional market integration on regional economic development gap was demonstrated.Finally,based on the research perspective of market integration,some policy suggestions were explored to narrow the regional development gap.The empirical results show that the internal market integration has a nonlinear effect on the regional economic unbalanced growth.And the external market integration process is obviously faster than the internal market integration process,and different regions due to the implementation of different economic policies,there have been different stages of economic development momentum.At the same time,due to the evolution of the national market integration process in the different stages of development,and the region economic development difference of internal structure is not the same,and interaction of internal and external market integration to the coordinated development of regional economic has differences,namely the eastern and central regions play a role of the alternative,and the eastern region effect is more obvious;And the western region has played a complementary role.
