摘要
近年来,在中国高技术产业内,企业规模结构经历着从集中化到两极化的悄然变化。为了解析企业规模结构的演化动因,本文构建动态面板Sys_GMM模型,对1995—2002年和2003—2010年的两组平衡面板数据进行分别回归和比较分析。研究证实了效率竞赛论、政府偏好论、分工深化论、市场容量论、两化融合论的理论解释力,但进入壁垒论和外资导入论未能得到实证支持。
In Chinese high-tech industry, the enterprise-scale structure has evolved from concentration to polarization recently. The paper analyzed the motivation of evolution with Sys_ GMM model and compared the regression results of two sets of data from 1995 to 2002 and from 2003 to 2010. And then it testified the influence of efficiency, government preference, division, market absorption and informationization. But entry barrier and foreign investment weren＇t proved.
