产业集聚与地区收入差距：一个动态均衡理论分析

基于新经济增长模型构建了产业集聚影响地区收入差距机制模型，并采用一般均衡分析方法动态考察了产业集聚、制度以及技术和劳动力等因素的变化对地区收入差距的影响，并进一步分析了经济从最初的不均衡状态向鞍点稳定均衡点的运动轨迹以及集聚因素对地区经济收敛的影响。结果表明：一方面，产业集聚存在一个最优规模，集聚水平过高或过低均不利于该地区经济发展；另一方面，在适度的范围内，提高产业集聚规模不仅能缩短地区收入差距收敛的时间，而且能缩小落后地区与发达地区经济发展差距。

Industrial Agglomeration and Regional Income Disparity: A Dynamic Equilibrium of Theoretical Analysis

Based on the new economic growth model , the mechanism model of regional income disparities affected by industrial agglomeration is built in the thesis, it adopts general equilibrium institution to dynamic investigate the affection degree of industrial agglomeration, technology and labor force to the regional income disparities, further analyzes the economy''s motion trail from the initial disequilibrium to the saddle point and point of stable equilibrium, and analyzes the influence of agglomeration factor on the regional economic convergence. The results indicate as follow. On the one hand, industry agglomeration has its optimal size, and the regional agglomeration level too high or too low determines the regional economical development. On the other hand, improving the level of industrial agglomeration in a moderate range can shorten the convergence time of the regional income disparities, but can also narrow the regional economic development disparities between the backward areas and developed areas.
