摘要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。 The relations between heterogeneity and technological innovation is one of important problems in evolutionary economics research. By comparison with different heterogeneity measures, a modified Euclidean distance measure is selected in measuring firm heterogeneity in Chinese industrial sectors. Using the data of 36 segments of industrial sectors in 2006 as samples, an empirical test is made to judge the relationship between firm heterogeneity and industry innovation ability, then draws the following conclusions： firm heterogeneity has a significant positive impact on the industry innovation capability, which means the higher the degree of heterogeneity, the more intense the industry innovation ability. In the aspect of control variables, the influence of the R＆D investment and market structure to the technological innovation ability are also quite remarkable, the greater the R＆D intensity and the more the number of finns in the industry, the more conducive to the promotion of industrial innovation ability.
