本文利用2009-2011年之间科技部创新型企业数据库中样本企业的面板数据，通过回归分析，实证检验了企业间合作和产学研合作对于企业国际化创新的影响，并探究了政府参与在该过程中的权变机制。研究发现，企业间合作和企业国际化创新绩效是正向的线性关系，而产学研合作对企业国际化创新绩效具有倒U型影响。政府参与正向调节企业间合作对国际化创新的影响，并改善产学研合作与企业国际化创新绩效之间的关系。

We use a 3-year panel data (from 2009 to 2011) from the Innovative Firms Database collected by the Ministry of Science and Technology of China (MOST) to test our model. Through regression analysis, we respectively test the effects of firm-firm cooperation and firm-university cooperation on firm international innovation, and explore the contingency mechanism by empirically testing the moderating effects of government involvement. Our results indicate that firm-firm cooperation positively leads to firm international innovation performance, while firm-university cooperation has an inverted U-shaped effect on firm international innovation performance. Besides, government involvement positively moderates the relationship between firm-firm cooperation and international innovation performance, and improves the relationship between firm-university cooperation and international innovation performance.
