【摘要】：本文通过一个改进的新新经济地理异质企业模型考察城市与企业之间的双向选择机制。理论分析表明,高效企业能制定较低的价格、占有较大的市场,因此倾向进入大城市,而低效企业倾向选择较小的城市;城市越大,对企业的门槛效率要求越高。大城市的企业效率分布曲线相比小城市有较高的左侧截尾,而小城市相对于大城市存在右侧截尾。本文利用中国工业企业微观数据检验企业固定效率在城市间的分布特征,估计显示城市效率门槛随城市规模增长而增长,筛选效应至少相当于传统集聚经济的1/5~2/5,但集聚经济和筛选效应对不同行业的企业影响有所差异。分析还表明,降低区间交易成本有助于城市间效率分布的趋同,市场一体化将提升中小城市生产率、缩小城市间差距。
[Abstract]:This paper investigates the two-way selection mechanism between cities and enterprises through an improved new and new economic geographical heterogeneous enterprise model. Theoretical analysis shows that efficient enterprises can set lower prices and occupy a large market. Therefore, they tend to enter big cities, while inefficient enterprises tend to choose smaller cities; The larger the city, the higher the threshold efficiency of the enterprise. Compared with the small city, the distribution curve of the enterprise efficiency in the big city has a higher left end. In contrast to large cities, small cities have a right truncation. This paper uses microcosmic data of Chinese industrial enterprises to test the distribution characteristics of fixed efficiency between cities, and estimates that the threshold of urban efficiency increases with the growth of urban scale. The screening effect is at least 1 / 5 / 5 of the traditional agglomeration economy, but the influence of the agglomeration economy and the screening effect on the enterprises in different industries is different. Reducing interval transaction costs is helpful to the convergence of efficiency distribution among cities. Market integration will improve productivity and narrow the gap between cities.
