安徽省生产性服务业集聚对城镇化效率影响实证研究

An Empirical Study on the Impact of Producer Services Agglomeration on Urbanization Efficiency in Anhui Province

新型城镇化建设进程受到区域产业发展影响,生产性服务业发展程度和集聚水平是城镇化效率的突破口,探寻二者联系具有现实意义。文章在对安徽省生产性服务业和城镇化现状分析基础上,用区位熵和非期望产出超效率SBM模型测算集聚水平和城镇化效率值,选取2011-2020年省内城市面板数据构建差分GMM模型和系统GMM模型研究生产性服务业集聚水平对城镇化效率影响。结果显示,生产性服务业集聚提升城镇化效率并且有时间滞后特点,经济发展水平在不同地区对城镇化效率作用不同,就业人数和外资直接投资都正面促进城镇化效率。提出加速生产性服务业聚集进程协同提升城镇化效率、加强区域生产性服务业集聚联动促进生产要素流动配置、发挥市场作用鼓励外资布局投资等建议。

The construction process of new urbanization is affected by the development of regional industries. The development degree and agglomeration level of producer services are the breakthrough of urbanization efficiency. It is of practical significance to explore the relationship between the two. Based on the analysis of the current situation of producer services and urbanization in Anhui Province, this paper uses location entropy and unexpected output super efficiency SBM model to calculate the agglomeration level and urbanization efficiency value, and selects the panel data of cities in the province from 2011 to 2020 to build a differential GMM model and a systematic GMM model to study the impact of the agglomeration level of producer services on urbanization efficiency. The results show that the agglomeration of producer services improves the efficiency of urbanization and has the characteristics of time lag. The level of economic development has different effects on the efficiency of urbanization in different regions. The number of employment and foreign direct investment both positively promote the efficiency of urbanization. Put forward some suggestions, such as accelerating the agglomeration process of it, improving the efficiency of urbanization, strengthening the agglomeration linkage of regional producer services, promoting the flow and allocation of production factors, giving play to the role of the market, and encouraging foreign investment.
