在标准经济地理模型的基础上，考虑到市场一体化过程中企业间的成本异质性，研究了不同企业异质性对区域协调政策的影响，为中国区域经济不平等提供了另一种解释机制。（2010），引入了跨地区投资补贴的概念，表明生产率较低的企业有可能向投资补贴的目标地区转移，从而缩小了地区发展的差距，但却扩大了地区生产率的差距，这不利于促进欠发达地区的可持续发展，从长期来看，继续推进市场一体化进程是最优的区域政策，也是为欠发达地区提供适宜的政策。
The standard economic geography model is extended to allow for cost heterogeneity across firms in response to market integration,enabling us to study the effects of regional coordination policies that vary according to firm heterogeneity,which permits another kind of explanation mechanism to the regional inequality in China.Based on the model of Okubo et al.(2010),the paper introduces investment subsidies across regions,and shows that lower productivity firms are likely to relocate to the targeted regions provided investment subsidy.As a consequence the gap of regional development decreases but the gap of regional productivity increases,which is not beneficial to promote the sustainable development of underdeveloped areas.And in the long run,to promote the process of market integration continuously is the optimal regional policy as well as providing appropriate policies for less developed areas.
