利用中国工业企业数据库2001~2011年的数据,研究了城市规模对中国工业企业生产效率的影响.研究发现,城市规模与企业生产效率存在倒U型关系;对于最大化生产效率而言,存在最优城市规模;不同行业对应的最优城市规模各不相同.估计得出,最优城市规模范围约为150~260万人口.中国目前只有40个城市在最优城市规模范围之内,有30个城市已经超过最优城市规模,其他211个城市低于最优城市规模.

This paper studys the impact of city scale on the production efficiency of Chinese industrial enterprises with Chinese indus-trial enterprise database.Our study finds that there is an inverted U-shaped relationship between firm size and production efficiency of the city,as with maximizing firm's productivity,there exists an optimal city size.Corresponding to different industries,the optimal city size each are not identical.It is estimated that the optimal size of the city is about 150-260 million.In China,only 40 cities are in the range of optimal size,there are 30 cities exceeded the optimal size of the city,and 211 cities below the optimal size of the city.
