摘要
作为中国能源供应体系中的重要分支,在创新推动发展的大背景下,国家对绿色能源发电产业的支持政策不断加强,政府补助政策在其中起到举足轻重的作用。以2011—2019年234家绿色能源发电上市公司为研究对象,采用动态面板GMM和门槛效应模型研究政府补助对绿色能源发电企业创新产出的作用效果。研究发现:政府补助于绿色能源发电企业创新产出的作用效果呈非线性结构特征,总体表现为先抑制后促进,然后再抑制;政府补助对绿色能源发电企业创新产出存在最优补助区间,低于最优补助区间时会诱发企业“寻租行为”,高于该区间则挤出企业自身创新投入,二者均会使企业创新行为受到负面影响;具体而言,中国目前绿色能源发电企业的补助政策不尽合理,大部分企业未落入“最优区间”,其中以风能企业最为严重;进一步将样本划分东中西部地区,发现东部地区的寻租行为相比中西部地区不甚明显,政府补助对东部地区的创新产出主要表现为促进作用,而中西部地区尚存在补助缺口,需要政府加大扶持力度。研究结果可为建立健全中国绿色能源产业政策体系和提升政府补助政策效益提供参考。
The green energy power generation industry is an important branch of China’s energy supply system.In the context of innovation-driven development,national support policies for this industry has been strengthened,in which government subsidy policies play a pivotal role.In this paper,the effect of government subsidies on the innovation output of green energy power generation companies was investigated using dynamic panel GMM and threshold effect model,with 234 listed companies of green energy power generation in 2011—2019 as research subjects.It is found that the effect of government subsidies on the innovation output of green energy power generation enterprises had a non-linear structure,and the overall effect was first inhibited,then promoted,and then inhibited again;there was an optimal range of government subsidies for innovation output of green energy power generation enterprises,below which the“rent-seeking behavior”was induced,and above which the enterprises would crowd out their own innovation input,both of which negatively affected the innovation of enterprises.Specifically,the subsidy policy of China’s current green energy power generation enterprises was not reasonable,and most enterprises did not fall into the“optimal range”,which was the most serious in wind energy enterprises.By further dividing the samples into eastern,central and western regions,it is found that rent-seeking behavior was less pronounced in the eastern region compared to that in the central and western regions,and government subsidies mainly promoted innovation output in the eastern region,while there was still a subsidy gap in the central and western regions,which need more government support.The results of the study can provide reference for establishing a sound policy system for China’s green energy industry and improving the effectiveness of government subsidy policies.
