国内市场分割、双重市场激励与企业创新

Domestic Market Segmentation,Dual Market Incentives and Enterprise Innovation

本文将国内市场分割因素纳入企业创新的分析框架,研究开放条件下国内市场分割如何影响企业受到的"双重市场激励效应"。理论分析发现:企业出口会同时存在"市场扩张效应"和"市场替代效应",当市场分割较小时,出口的"市场扩张效应"更大,企业受到的"双重市场激励效应"更强;而当市场分割较高时,出口的"市场替代效应"明显,企业受到的"双重市场激励效应"较弱。本文采用中国工业企业数据的实证检验发现:(1)开放条件下,企业创新受到"双重市场激励"的影响,内销规模和出口规模都会显著促进企业创新;(2)市场分割对"双重市场激励效应"存在显著的负向调节作用,会降低内销规模和出口规模对企业创新的促进作用;(3)市场分割会加剧企业出口倾向,但会降低内销规模,产生"市场替代"现象,从而降低"双重市场激励效应";(4)"双重市场激励"能显著提升企业发明创新占比,而市场分割同样会削弱"双重市场激励"对企业发明创新占比的提升效应。本文的研究表明,整合国内市场、发挥大国市场优势能进一步释放国内国际"双重市场"对企业创新的激励作用,助力企业创新发展。

In this paper,the factor of domestic market segmentation is incorporated into the framework of firm innovation to study how domestic market segmentation affects the“dual market incentive”effect that was received by firms under the conditions of opening up.Our theoretical analysis proves that the export of enterprises will have both“market expansion effect”and“market substitution effect”.When the market segmentation is smaller,the“market expansion effect”of export is larger,and the“dual market incentive”effect is stronger.Whereas the market segmentation is higher,the“market substitution effect”of export is bigger,and the“dual market incentive”effect is relatively weaker.Based on the China Industry Business Performance Data,our empirical estimation shows that:(1)Under the conditions of opening up,firm innovation is affected by“dual market incentive”effect,and both domestic and export scale will significantly facilitate firm innovation;(2)Market segmentation has a significant negative moderating effect on the“dual market incentive”effect,which reduces the promotion effect of firm innovation that domestic sales and export scale have impact on;(3)In terms of mechanism,market segmentation will increase the export tendency of enterprises,but reduce the scale of domestic sales,resulting in“market substitution”phenomenon,thus reducing the“dual market incentive”effect;(4)“Dual market incentive”effect can significantly improve the proportion of firm’s invention innovation,while market segmentation can also weaken the promotion effect of“dual market incentive”in terms of firm’s innovation invention.This research shows that integrating domestic market and giving full play to the advantages of big market can further release the incentive effect of domestic and international“dual market”on enterprise innovation,and promote enterprise innovation development.
