“新”新经济地理学引入企业异质性使产业集聚理论有了突破性的发展,而技术的异质性对经济行为差异的影响尤为明显。基于1998~2009年中国工业企业数据库的实证研究表明:行业技术密集程度越高其集聚现象越明显,且技术密集程度越高的行业,其行业内的技术异质性也越大;通过将行业划分为高技术、中高技术、中低技术和低技术四大类型,采用面板数据进行固定效应和随机效应模型分析,研究发现,行业内技术异质性是一种集聚力,随着技术异质性的增大,产业集聚程度也在加强。
The introduction of corporate heterogeneity in the “new” new economic geography has led to a breakthrough in the development of industrial agglomeration theory, and the heterogeneity of technology has had a particularly pronounced effect on economic behavior differences. Based on the empirical research of Chinese industrial enterprises database from 1998 to 2009, it shows that the higher the technology concentration of the industry is, the more obvious is its agglomeration phenomenon, and the higher the technology-intensive industry, the greater the technical heterogeneity in the industry; Divided into four major types: high-tech, medium-high technology, low-tech and low-tech, using panel data for fixed-effect and random-effects model analysis, the study found that industry heterogeneity is a kind of cohesion, with heterogeneous technologies. With the increase of sex, the degree of industrial agglomeration is also strengthened.
