中国出口贸易溢出对企业创新能力的影响

The Effect from Technology Spillovers of Exports to Capacity of Enterprise Innovation in China

本文利用2005~2008年中国工业企业微观数据,研究了出口贸易溢出对企业创新能力的影响。为了修正样本选择偏差问题,文中使用了Heckman两步模型。研究发现,出口贸易水平溢出和后向关联溢出对企业创新可能性和创新数量均有显著的正效应。进一步的研究表明,内资企业是出口贸易溢出的主要来源;外资出口企业的强势竞争力、买方市场势力及其对知识产权的严格保护是外资企业出口溢出对企业创新能力影响较小的主要原因。

Using the micro data of China＇s manufacturing enterprises in 2005-2008, this paper study the relationship of export trade in technology spillovers between innovation capacity. In order to correct the sample selection bias problem, we use the Heekman two-step model.The study found that, in china ,there are significant positive effect of horizontal spillover and backward spillover of exports on innovation performance, further study found that domestic enterprises are the main source of technology spillover; foreign export enterprise strength of competitiveness, the fm^nation of buyer market forces, and the strict protection of intellectual property are the main reasons that foreign-funded export spillover less impact on enterprises＂ innovation ability.
