出口退税和创新补贴政策效应研究

Policy Effect of Rebating Export Tax and Subsidizing Innovation in Innovation Incentive

本文构建了一个南北间的静态古诺模型来研究创新激励政策的有效性。研究结论表明,在一定劳动力资源禀赋结构和劳动力市场环境下,发展中国家的出口退税和创新补贴政策能有效激励创新产出,从而提高本国的企业利润、消费者剩余,增加社会福利。但从长远来看,国民教育水平和劳动者素质是决定国家创新产出的根本因素。我们对上述结论还进行了实证检验,发现在我国创新补贴是有效的创新激励措施,而创新补贴政策却不一定有效,其政策效果具有一定的不确定性。

The policy effect of innovation-incentive is examined with a static cournot competition model in this paper. Results show that under certain labor structure and labor-market environment subsidizing innovation and rebating export can incent innovation. The effective innovation incentive policy can also inspirit native company profit, consumer surplus, social surplus. Actually, national education and human capital really decide native science and technology level in long views. Finally, we use econometric model to prove our mathematical model, argue that in today＇s China rebating export can ineent innovation, but subsidizing innovation fail to do that, its policy effect is uncertain.
