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.
