企业异质性与产业创新能力——基于我国36个工业行业的实证检验Firm Heterogeneity and Industry Innovation Capability——Based on the Empirical Test of 36 Chinese Industrial Sectors

摘要(Abstract)：
异质性与技术创新之间的关系是演化经济学研究的重要问题之一。本文基于异质性衡量方法的比较,选择修正后的欧氏距离法对我国工业行业中企业的异质性加以测算。以2006年36个工业行业的统计数据为样本,就企业异质性与产业创新能力之间的关系进行了实证检验,得到如下研究结论:企业异质性对产业创新能力具有显著的正效应,异质性程度越高,产业创新能力越强;控制变量方面,研发投入和市场结构对技术创新能力的影响也比较显著,研发强度越大,行业内企业数量越多,越有利于产业创新能力的提升。
关键词(KeyWords)： 企业异质性;产业创新能力;工业行业;研发强度;市场结构
