中文摘要：

利用2004~2008年44 126家中国制造业企业数据,整合委托代理理论、制度理论和资源理论,研究了所有制类型对企业创新效率的影响,并进一步分析了行业异质性、区域异质性对不同所有制企业创新效率的调节作用。研究发现,国有企业的创新效率不如非国有企业;行业集中度正向调节所有制对创新效率的影响;行业技术机会对企业创新效率有促进作用,但负向调节所有制对创新效率的影响;行业进入壁垒对企业的创新效率有负向影响,但正向调节所有制对创新效率的影响。

英文摘要：

By using a balanced panel dataset of 44 126 firms from the Chinese manufacturing industry for the period of 2004~2008,and integrating Principal-agent Theory,Institutional Theory and Resource-based Theory,we analyzed the impact of ownership types on enterprise innovation efficiency,and further analyzed the moderating effects of industry and regional heterogeneity on different ownership enterprise’s innovation efficiency.The empirical findings suggest that：1the state-owned enterprise innovation efficiency is lower than non-state-owned enterprises;2the industry concentration on enterprise innovation efficiency is negative,but has a positive moderating effect on the relationship between ownership types and innovation efficiency;Technical opportunity promotes enterprise innovation efficiency,but weakens the relationship between ownership types and innovation efficiency;the impact of entry barriers to the enterprise innovation efficiency is negative,but strengthens the relationship between ownership types and innovation efficiency;The higher the degree of marketization is,both state-owned enterprises and non-state-owned ones’ innovation ability are stronger.The empirical findings can contribute to building the balance innovation-oriented mechanism between stateowned enterprises and non-state-owned enterprises and adding up the theoretical content of Chinese enterprise ownership type.
