摘要
发展现代服务业是推动我国经济转向高质量增长的关键。基于2004-2017年全国285个地级市的面板数据,从经济效益、社会效益及资源环境效益三个维度构建城市经济绩效综合指标评价体系,采用空间杜宾模型实证分析生产性服务业集聚对城市经济绩效的影响。研究表明,生产性服务业专业化集聚和多样化集聚均有助于提升城市经济绩效,并存在显著的正向外部溢出效应,其空间溢出边界分别为350公里和300公里,表现出省域内溢出的特征。异质性分析发现,高端生产性服务业集聚的特大城市和大城市适合多样化集聚模式,而低端生产性服务业集聚的中小城市适合专业化集聚模式。面板门槛回归结果显示,对外开放水平具有显著的门槛特征,对外开放水平对专业化集聚和城市经济绩效关系的约束作用在特大城市和大城市成立,而对多样化集聚和城市经济绩效关系的约束作用显著存在于中小城市。因此,生产性服务业集聚应同城市经济发展阶段和产业结构相匹配,而不能盲目追求生产性服务业的堆砌式发展。
Developing modern service industry is the key to motivating China’s economic high-quality growth. Based on the panel data of 285 prefecture-level cities in domestic China from 2004 to 2017,this paper builds a comprehensive index evaluation system of urban economic performance from three dimensions of economic benefit,social benefit,resource and environmental benefit,and conducts empirical analysis of the impact of agglomeration of productive service industries on urban economic performance using a spatial Dubin model. The research shows that both specialized and diversified agglomerations of productive service industries are conductive to improving urban economic performance,and there exists significant positive external spillover effect. The spatial spillover boundaries are 350 km and 300 km,respectively,presenting intra-provincial spillover characteristics. Heterogeneity analysis finds that megacities and large cities with high-end productive service industries are suitable for diversified agglomeration model, while small and medium-sized cities with low-end productive service industries are suitable for specialized agglomeration model. The panel threshold regression results show that the opening up level shows significant threshold characteristics. The restraining effect of opening up level on the relationship between specialized agglomeration and urban economic performance can be established in megacities and large cities. While the restraining effect on the relationship between diversified agglomeration and urban economic performance significantly exist in small and medium-sized cities. Therefore,the agglomeration of the productive service industries should match urban economic development stage and industrial structure,rather than blindly pursuing the pilling-up development of productive service industries.
