摘要
开发区的建设在我国企业技术创新、产学研结合和城市发展中发挥了不可替代的作用,普遍认为开发区内企业的创新水平较高。而经济的空间集聚可以通过增强企业间人员的交流、学习等提高企业的创新能力。本文使用上海企业的研发、专利和地理数据等,首先研究了集聚度对开发区创新作用的影响,其次重点研究了不同集聚类型在开发区创新作用中的异质性影响。结论显示开发区显著提高了企业的空间集聚程度,而这种集聚是开发区促进企业创新的重要渠道。开发区内形成研发要素集聚对创新投入和产出都有显著促进作用;开发区内形成的产业垂直和水平集聚则仅仅显著促进研发投入。
Special Economic Zones(SEZs) plays an irreplaceable role in innovation, production and research integration as well as urban development of China. While it is generally believed that the innovation level of firms in SEZs are relatively high, and the spatial agglomeration can also enhance the exchange of ideas, which could also improving firm innovation. This paper uses the R&D expenditure data , patent application data and some geography data of Shanghai manufacture firms to, firstly, identify the influence of the agglomeration on the innovation role of the SEZs;secondly, to study the heterogeneity effect of different agglomeration types in the innovation role of the SEZs. The conclusion shows that the SEZs has significantly improved the degree of firms' spatial agglomeration, and this agglomeration is an important channel for the SEZs' promoting firm innovation. And agglomeration of R&D factors in the SEZs significantly promotes innovation input and output;while vertical and horizontal agglomeration in SEZs only significantly promotes R&D investment.
