The Yangtze River Economic Belt is the most important manufacturing economic belt in China. The level of manufacturing green innovation efficiency of the Yangtze River Economic Belt directly affects the overall competitiveness of China's manufacturing industry. With panel data from 11 provinces and cities along the Yangtze River Economic Belt in China for the period of 2008 to 2017, this paper applies the slacks-based measure (SBM)-data envelopment analysis (DEA) model and panel Tobit model to conduct an empirical study of the effects of government research and development subsidies and environmental regulations on the green innovation efficiency of the manufacturing industry of the Yangtze River Economic Belt. The results show that, firstly, government R&D subsidies and environmental regulations are both conducive to improving the green innovation efficiency of the manufacturing industry of the Yangtze River Economic Belt; secondly, because of the fact that the interaction terms between government R&D subsidies and environmental regulations failed to pass the significance test, the positive moderating effects of R&D subsidies on environmental regulations and green innovation efficiency of the manufacturing industry are not obvious; thirdly, in terms of control variables, strengthening agglomeration is the only factor that is positively correlated with green innovation efficiency improvement of the manufacturing industry. Enterprise scale and industrial structure have negative effects on green innovation efficiency improvement, and the openness of economy has no correlation with green innovation efficiency.
长江经济带是中国最重要的制造业经济带。长江经济带制造业绿色创新效率的水平直接影响中国制造业的整体竞争力。本文利用中国长江经济带 11 个省市 2008 年至 2017 年的面板数据，运用基于松弛的测度（SBM）-数据包络分析（DEA）模型和面板 Tobit 模型，对政府研发补贴和环境规制对长江经济带制造业绿色创新效率的影响进行了实证研究。结果表明：首先，政府研发补贴和环境规制都有利于提高长江经济带制造业的绿色创新效率；其次，由于政府研发补贴与环境规制的交互项未通过显著性检验，研发补贴对环境规制和制造业绿色创新效率的正向调节作用不明显；再次，在控制变量方面，加强集聚是唯一与制造业绿色创新效率提高呈正相关的因素。企业规模和产业结构对绿色创新效率的提高有负面影响，而经济开放度与绿色创新效率没有相关性。
