企业规模作为类别自变量,能够更有效地揭示不同规模企业技术创新影响的差异化和产业政策在特定情境下的有效性。本文基于我国2007—2012年制造业上市公司面板数据,运用门槛回归模型研究公司规模对企业技术创新的门槛效应,研究表明企业规模对技术创新的作用存在明显的阈值,并且两者之间的关系受到市场集中度、行业特征、政府补助等因素的限制和影响。研究认为门槛回归模型很好地解释了公司规模与技术创新之间的复杂非线性关系和跃迁过程,相应的研究结论在产业组织结构、企业成长和产业创新投入等方面,为企业管理和产业政策制定提供了科学依据。
As a category variable, enterprise size can reveal the difference of technological innovation impact of different scale enterprises more effectively and the effectiveness of industrial policy in specific situations. Based on the panel data of manufacturing listed companies from 2007 to 2012 in our country, this paper uses the threshold regression model to study the threshold effect of firm size on technological innovation in enterprises. The research shows that there is a clear threshold for the effect of firm size on technological innovation and the relationship between the two By the market concentration, industry characteristics, government subsidies and other factors, restrictions and effects. The research suggests that the threshold regression model can well explain the complex non-linear relationship and transition process between company size and technological innovation. The corresponding conclusion is that for enterprise management and industrial policy in the aspects of industrial organization structure, business growth and industrial innovation investment, Formulated to provide a scientific basis.
