中国高技术产业创新效率研究——基于SFA方法的实证分析

An empirical analysis on China's high-technology industry innovation efficiency based on SFA

高技术产业的创新能力决定着一个国家国际竞争力的高低及其在世界经济中的分工地位。应用SFA方法对中国高技术产业创新效率进行了实证分析。研究表明,中国高技术产业整体创新效率呈改善的趋势;其中,电子计算机及相关行业创新效率最高,装备制造业创新效率最低;科技人员在高技术产业创新中的产出弹性弱于科研经费的产出弹性,中国高技术产业创新产出主要是经费拉动型的。在创新效率影响因素的分析中,企业数量对于创新效率有不显著的负向影响,而产业内三资企业总资产、产业利润对于创新效率有着明显的正向影响。为此,提高中国高技术产业创新效率需要进行制度创新,充分发挥科研人员创造性;提高产业集中度,组建大型产业集团,为产业创新提供足够的资金支持;适当提高产业开放度,促进中资企业获得技术溢出。

The paper applies SFA method to analyze China＇ s High -Technology industry innovation efficiency. The study indicates, the innovation efficiency of China＇ s High - Technology industry is improving; Electronic computer and related occupations has the highest innovation efficiency, the equipment manufacturing industry has the lowest innovation efficiency; The innovation output elasticity of research personnel is much lower than research fund. AS to effect factors, corporation quantity has a negative function indistinctively; Foreign - funded enterprises assets and industry profits have remarkable positive function. Therefore,in order to improve innovation efficiency , China＇ s High -Technology industry should proceed institution innovation; promote industry concentration ratio; advance industry Openness properly.
