中文摘要：

文章从区域差异的视角探讨了产业结构升级与城市生产率之间的关系,并以中国286个地级市为研究样本,构建了空间面板计量模型并进行了实证检验。结果表明：中国城市生产率存在显著的空间集聚效应,产业结构升级能有效提升城市生产率,但这种提升作用在不同区域的作用效果存在较大差异。东部地区产业结构升级对城市生产率有显著的正向促进作用,中部地区产业结构升级对城市生产率的作用效果为负,而在西部地区产业结构升级提升生产率的效果则不显著。此外,物质资本投资、人力资本投资、城镇化发展、外商直接投资、基础设施水平等对城市生产率有一定的正面影响,以进出口总额为衡量标准的对外开放度对城市生产率存在负面影响。

英文摘要：

This paper analyzes the relationship between the upgrading of industrial structure and urban productivity from the aspect of regional differences and by taking 286 county - level cities as research samples, the paper constructs a spatial econometric model to make an empirical research. The results show that urban productivity has significant spatial agglomeration effect. The upgrading of industrial structure promotes urban productivity effectively, but the improvements seem totally different in different regions. The upgrading of industrial structure has significant positive effect on urban productivity in eastern regions, the effect is negative in central regions, while for the western regions the effect is insignificant. In addition, physical capital investment, human capital investment, urbanization development, foreign direct investment and infrastructure have certain positive effects on urban productivity, but the opening degree of cities, as measured by the total amount of import and export, has negative influence on urban productivity.
