摘要
基于中国2003-2018年261个城市的面板数据,运用空间计量模型,分析生产性服务业集聚和城市规模对城市生产率的影响及其作用机理。结果显示:生产性服务业集聚和城市生产率存在“倒U型”关系,城市规模和城市生产率也呈现“倒U型”关系;生产性服务业“集聚红利”的发挥受制于城市规模,城市“规模红利”的大小和生产性服务业集聚水平相关,两者的协同效应对城市生产率有积极影响。据此,本文认为中国大部分城市的生产性服务业集聚还未达到最优水平,集聚红利有限,同时,除了部分城市实现规模经济外,多数城市并未达到最优规模。
Based on the panel data of 261 cities in China from 2003 to 2018,the spatial econometric model was used to analyze the impact of the agglomeration of producer service industry and urban scale on urban productivity and its mechanism.The results show that:first,there is an"inverted U"relationship between agglomeration of producer service industry and urban productivity,and the relationship between urban scale and urban productivity is also"inverted U";second,the exertion of the"agglomeration dividend"of producer service industry is subject to the urban scale,and the size of the urban"scale dividend"is related to the level of agglomeration of producer service industry,and the synergistic effect of the two has a positive impact on urban productivity.Based on this,the paper puts forward that the agglomeration of producer services in most cities in my country has not reached the optimal level and the agglomeration dividends are limited.At the same time,except for some cities that have achieved economies of scale,most cities have not reached the optimal scale.
