中国汽车产业环境技术创新影响因素实证研究

Influencing Factors of Environmental Technology Innovation on Chinese Auto Industry

基于动态计量模型,以我国汽车产业为对象,从产品创新和过程创新2个方面实证研究了环境政策、技术进步、市场结构、产业特征对汽车产业环境技术创新的影响。结果表明,环境政策中的环境影响评估制度和污染限期治理制度、技术进步中的R&D投入和人力资本存量、市场结构中的产品销售利润率与环境技术创新存在长期均衡关系,且长期均衡对产品创新短期波动的影响不大,仅有污染限期治理和R&D投入的长期均衡对过程创新短期波动的影响显著。此外,环境影响评估制度、R&D投入、人力资本存量、产品销售利润率均为产品创新和过程创新的格兰杰原因,而污染限期治理是产品创新的格兰杰原因,过程创新是污染限期治理的格兰杰原因。

Based on the dynamic econometric model,this paper takes the auto industry of China in 1999-2008 as example and empirically studies the impact of environmental policy,technological progress,market structure and industrial characteristics on environmental technology innovation from both product and process innovation.The result shows that： environment in environmental policy impacts on assessment system and pollution control system within a time limit,RD investment and human capital in technological progress and product sales margins of market structure have long term equilibrium relationship with environmental technology innovation.And its long-run equilibrium has little effect on the short-term fluctuations in product innovation other than the one of a pollution limit control and RD investment.Meanwhile,environmental impact assessment system,RD investment,human capital,product sales margins are all Granger causalities about product and process innovation,pollution within a time limit is Granger causality of product innovation,and process innovation is Granger causality the pollution of the deadline.
