高技术产业创新特征差异性实证分析

Empirical Analysis on the Differences of Innovation Characteristics of China's High-tech Industry

基于高技术产业的演化规律,实证研究了高技术产业的创新特征差异性。研究表明,利润增长与研发投入之间关系不是很强并呈越来越强的趋势;利润增长与新产品开发投入之间关系较强但趋势越来越弱;新产品开发对研发的依赖性较强并呈越来越强的趋势。研发投入和新产品开发投入对利润贡献均比较小,意味着高技术产业研发效率和新产品开发效率比较低或高技术产业的界定标准还存在一定问题。

Based on the evolutionary law of industry, we study the differences of innovation characteristics. Results show that there is no strong relationship between profit growth and R＆D investment although the trends is increasing; there is strong relationship between pro{it growth and new product development investment, but the trend is increasingly weak; there is strong relationship between new product development and R^D investment, although it has a growing trend; R＆D and new product development investment both contribute small to the total profit, which means that the efficiency is still relatively low for R＆D and new product development, or the standards defining high-tech industry may be also a problem.
