基于国家高新区高成长企业的产业集聚研究

Industrial Agglomeration of High Growth Enterprises in China's High-tech Zones

利用2010-2013年中国高新区企业统计数据,按照瞪羚企业初选标准,选取具有高成长特征企业,研究这类型企业的产业地理集聚状况。利用Ellison和Glaeser(1997)的产业集聚指数(即EG指数),测算高新区高成长企业在涵盖的103个城市之间的集聚情况。结果发现:高新区高成长企业在4年内集聚程度逐渐加强。同时,行业之间差异较大。集聚程度最高的有房地产业、租赁和服务业、批发和零售业、信息传输软件和信息技术服务业、金融业、科学研究和技术服务业等。而教育、采矿业、卫生和社会工作等行业的集聚现象不明显。高新区高成长企业代表地区经济发展未来,这些发现表明产业地理集聚将进一步加强。同时,要关注产业之间的异质性,引导产业错位发展,提升资源配置效能。

This paper uses statistical data of high growth enterprises in China's high-tech zones from2010 to 2013 to estimate the industrial agglomeration.In specific,it applies Ellison and Glaeser(1997)industrial agglomeration index(i.e.,EG index)to calculate the geographic concentration of high growth enterprises in high-tech zones among 103 cities in China.The results show that the agglomeration degree of these industries increased gradually in these four years,and the gap between different industries are quite large.Industries of the highest degree of concentration include real estate,leasing and service,wholesale and retail,information transmission software and information technology services,financial services,scientific research and technical services.Agglomeration in education,mining,health and social work is not significant.As high growth enterprises in China's hightech zones stands for the future of regional economic development,the findings suggest that the regional industrial agglomeration will be further strengthened.Therefore,the government should pay close attention to the heterogeneity of industries,guide them to develop industries with local advantages and increase the resource allocation efficiency.
