政府补贴、产品转换与出口质量

Government Subsidies,Product Switching and the Quality of Export Products

文章将产品转换率作为中介变量,基于2000-2013年中国工业企业和海关进出口贸易匹配数据,依次采用面板回归、中介效应检验和Bootstrap双重门槛回归方法,验证政府补贴通过影响产品转换率进而提升出口质量的传导途径与作用效果。实证结果表明:政府补贴通过降低企业创新的相对门槛提升了产品转换率;产品转换率是政府补贴影响出口质量的重要渠道,但其作用过程是非线性的;适度补贴下产品转换率对出口质量的影响最显著,低度补贴存在滞后效应,过度补贴则产生寻租效应。本研究为政府准确选择补贴对象、科学调整补贴强度进而提高补贴效率提供了可靠的依据。

Based on the matched data of Chinese industrial enterprises and customs trade statistics from 2000-2013,with product switching efficiency as mediating variable,this paper uses panel regression,mediating effect model and bootstrap double threshold panel model to study the channel of and effects of which government subsidy improves the firm’s export quality through influencing product switching.The empirical results show that:(1)the subsidy impacts product switching in exports through reducing the relative threshold of innovation;(2)product switching is an important channel for the subsidy to affect the export quality.However,the affecting process is non-linear;(3)the moderate subsidy is conducive to strengthen positive effect on product switching significantly,while the low subsidy has the lag effect and the excessive subsidy has the rent-seeking effect.The above conclusions provide reliable implications for the government to choose the subsidy types reasonably,adjust the subsidy intensity scientifically and improve the subsidy efficiency.
