政府创新补助对工业企业碳强度影响路径研究——一个链式多重中介模型检验

Research on the Impact Path of Government Innovation Subsidy on Carbon Intensity of Industrial Enterprises——Test of a Chain Multiple Mediation Model

研究以政府创新补助为切入点考察政府创新补助对工业企业碳强度作用机理。结果表明:政府创新补助能够显著降低工业企业碳强度,通过激励企业开展技术创新、降低融资约束的独立中介渠道以及“降低融资约束→激励技术创新”的链式中介渠道降低工业企业碳强度,其中激励企业技术创新的独立中介效应占比最高。将政府非创新补助纳入对照研究表明,具有创新导向的政府补助激励工业企业开展技术创新并缓解融资约束作用更强,降低企业碳排放力度更大。进一步研究表明,提升环境压力有助于发挥政府创新补助对于工业企业的碳强度治理效应。研究结论对于完善政府补助政策,最大化发挥其激励工业企业技术创新、缓解融资约束并降低碳强度具有重要意义。

The research takes the government innovation subsidy as the starting point to investigate the mechanism of the government innovation subsidy on the carbon intensity of industrial enterprises.The results show that the government innovation subsidy can significantly reduce the carbon intensity of industrial enterprises.It can reduce the carbon intensity of industrial enterprises through the independent intermediary channel of encouraging enterprises to carry out technological innovation and reducing financing constraints and the chain intermediary channel of“reducing financing constraints→encouraging technological innovation”,among which the independent intermediary effect of encouraging enterprise technological innovation accounts for the highest proportion.The inclusion of government non innovation subsidies into the comparative study shows that the government innovation subsidy has a stronger role in encouraging industrial enterprises to carry out technological innovation and easing financing constraints,as well as reducing enterprise carbon emissions.Further research shows that increasing environmental pressure helps to give play to the carbon intensity governance effect of government innovation subsidies on industrial enterprises.The research conclusion is of great significance to improve the government subsidy policy and maximize its role in stimulating technological innovation of industrial enterprises,alleviating financing constraints and reducing carbon intensity.
