Abstract：
Using the stochastic frontier analysis method of the Cobb-Douglas production function, this paper measures the impact of urban scale distribution of 25 Chinese cities on the regional innovation efficiency during the period of 2007 to 2014.It then adopts cluster analysis to further study the geographical division based on their joint relationships. The results show that: 1) there is an inverted U-type relationship between urban scale distribution and regional innovation efficiency, that is, there is an optimal urban scale distribution that maximizes regional innovation efficiency, and under or over concentrated urban scale is not conducive to the improvement of that efficiency. 2) There are four new types of geographical regions in China, and there are great differences in urban scale distribution and regional innovation efficiency among different types of regions. Overall, the two factors match each other to a greater extent in eastern coastal cities than in mid-west cities. Based on this, this paper argues that a further optimization of urban scale distribution should be adopted in order to effectively improve the efficiency of regional innovation and promote regional economic development.
