此前的文献普遍发现，中国大多数城市在20世纪90年代都处于规模偏小的状态。然而，自2000年后中国开始经历更快的城市化和深度市场化以来，人们对中国的城市群是如何演变的知之甚少。基于2000年至2013年281个城市的面板数据，我们的空间面板数据回归结果表明，城市规模对城市生产率的规模影响呈倒U形，并且随着城市产业结构变得更加以服务业为主导，其影响将增强。中国城市群之间也存在显著的空间相互作用和空间异质性。此外，我们计算了每个城市的最优规模，发现近年来中国大多数城市的规模仍然偏小。基于我们的研究结果，我们认为，中国政府应该在其新型城镇化战略中重点促进中等城市的充分增长。(C)2017爱思唯尔B.V.保留所有权利。
The previous literature has generally found that most Chinese cities were undersized in the 1990s. However, little is known about how urban agglomeration in China has evolved since the country began to experience much faster urbanization and deep marketization after 2000. Based on panel data of 281 cities between 2000 and 2013, our spatial panel data regression results show that the scale impact of city size on urban productivity appears to have an inverted U shape, and its effect will grow when the cities' industrial structure becomes more dominated by the service sector. There are also significant spatial interactions and spatial heterogeneity of urban agglomeration among Chinese cities. Furthermore, we compute the optimal size for each city and find that most Chinese cities are still undersized in recent years. Based on our findings, we argue that the Chinese government should focus on promoting sufficient growth of medium sized cities in its new urbanization strategy. (C) 2017 Elsevier B.V.
