生产性服务业集聚、空间溢出与质量型经济增长——基于中国285个城市的实证研究

Productive service industry agglomeration,spatial spillover and quality based economic growth:an empirical study based on 285 cities in China

中国经济增长方式已转向质量型经济增长。基于外部性理论和新经济地理理论的分析框架,从生产性服务业集聚作用于中国经济增长质量的影响机制着手,运用全国2003-2016年285个城市的面板数据构建空间计量模型,探讨生产性服务业集聚对地区经济增长质量的影响。分析结果发现,中国经济的质量型增长受制于生产性服务业的专业化集聚和多样化集聚,但当考虑人力资本、城市经济发达程度和政府干预行为等因素的影响时,生产性服务业集聚对经济增长质量提升的抑制作用得到了一定程度的缓解;且区域差异、城市规模和行业特征等约束条件的不同会影响生产性服务业集聚作用于地区经济增长质量的效果。此外,从集聚外部性视角来看,MAR外部性对经济增长质量的积极影响相对显著。

China’s economic growth pattern has turned to quality-based economic growth. Based on the analysis framework of the externality theory and the new economic geography theory,this paper uses the panel data of 285 cities in China from 2003 to 2016 to construct a spatial measurement model,and starts with the influence mechanism of the producer service industry agglomeration on the quality of China’s economic growth,in order to discuss the impact of it. The analysis found that the quality growth of China’s economy is subject to the specialized agglomeration and diversification of the producer service industry. However,when considering the influence of human capital,urban economic development and government intervention behavior,the restraining effect of producer service industry agglomeration on the quality improvement of economic growth has been alleviated to a certain extent. Different constraints of regional differences, city size and industry characteristics will affect the effect of agglomeration of productive services on the quality of regional economic growth. In addition,from the perspective of agglomeration externalities,the positive impact of MAR externality on the quality of economic growth is relatively significant.
