摘要
中国供给侧结构性改革的关键在于化解制造业的产能过剩矛盾。基于2005年和2012年世界银行营商环境调查数据,考察中国制造业企业创新活动对产能利用率的影响。结果表明,研发投入可以显著提高企业的产能利用率,并且过剩企业的研发投入对产能利用率的促进作用更为突出。采用工具变量回归分析和联立方程组模型克服内生性后,以上结论依然成立。进一步将创新方式细分为自主创新、合作创新及模仿创新后发现,自主创新活动有利于企业持续、稳定地消除过剩产能,合作创新的效果次之,而模仿创新并不具有化解产能过剩的作用。因此激发企业自主创新活力,鼓励企业强化自主品牌产品或服务的供给创新,是我国治理产能过剩的根本途径。
The key to current supply side structural reformation is how to mitigate overcapacity. Based on the data of the World Bank business environment and enterprise performance survey,this paper analyzes the effect of RD activities on capacity utilization of Chinese manufacturing enterprises. The results of our examination present some evidences. Firstly,RD investment plays a significantly positive role in increasing capacity utilization. Secondly,RD activities of enterprises with overcapacity have a greater positive impact on capacity utilization. The conclusion remains valid after we overcome the problem of endogenous by using the instrumental variable regression and simultaneous equations model. Further to subdivided the innovation mode into independent innovation,cooperative innovation and imitation innovation,we find that independent innovation activities are the most robust and effective approaches in removing excess capacity followed by cooperative innovation,but imitation innovation does not have the effect on alleviating excess capacity. To activate enterprise independent innovation,and encourage enterprises to strengthen the supply of independent brands products or service,is the fundamental way to resolve the problem of overcapacity.
