本文在研究产业外部性与地区经济转型发展的关系机理的基础上,采用浙江省2005-2014年制造业数据,分析了MAR外部性和Jacobs外部性对浙江省经济转型发展的影响。研究结果表明:随着经济发展水平的提高,MAR外部性对地区经济绩效的影响处于“N”型后半段,对产业结构的优化方面并不总是起促进作用;Jacobs外部性对经济绩效的影响随着经济发展水平的提高,由显著的负向影响转为显著的正向影响,对产业结构的影响在产业周期的不同阶段是不同的。最后,从产业集聚角度提出了加大资本技术投入、调整优化产业结构、完善外商投资政策、加强政府服务型职能、引进培育高层次复合型人才等建议。
Based on the study of the relationship between industrial externality and regional economic restructuring and development, this paper uses the manufacturing data from 2005 to 2014 in Zhejiang Province to analyze the impact of MAR externalities and Jacobs externalities on the economic restructuring and development of Zhejiang Province. The results show that: with the improvement of economic development, the impact of MAR externality on regional economic performance is in the latter half of “N ” type, and it is not always possible to promote the optimization of industrial structure; The impact of economic performance With the improvement of economic development, the significant negative impact has been transformed into a significant positive impact. The impact on industrial structure is different at different stages of the industrial cycle. Finally, from the industrial agglomeration point of view, we put forward some suggestions such as increasing investment in capital and technology, adjusting and optimizing industrial structure, perfecting foreign investment policy, strengthening government service-oriented functions, and introducing high-level compound talents.
