摘要
从企业异质性的角度研究科技创新和企业增长的关系。利用四川省近千家高新技术企业的数据,采用分位回归法进行回归分析,从而得到与最小二乘回归法相比的不同结果。研究发现,研发产出对不同增长速度的企业的影响显著且趋同;增长速度越快的企业其研发人员比例越趋于增加;增长越快,企业规模的负效应越大。为此建议制定普遍而宽广的政策鼓励大多数高科技企业发展。
This paper studies the relationship between scientific and technological innovation and enterprise growth from the perspective of heterogeneity.In this paper,data from about 1000 enterprises in Sichuan is used,and based on the angle of heterogeneity among enterprises,quantile regression analysis is used,which leads a way to distinctive results compared with OLS.It comes to the conclusion that,first,the innovation output has a significant effect on different growth rates of enterprises,but there are not distinctive effect among them;second,the faster an enterprise grows,the more it increases in the ration of innovation employee over total employee;and third,the faster an enterprise grows,the bigger negative effect of capital size will rise.
