摘　　要：基于产业集聚的视角研究科技创新成果与绿色全要素生产率的关系对促进中国科技创新与绿色经济协同发展,保障产业发展和环境保护步调一致具有重要战略意义。文章基于2008—2019年中国30个省市的省级面板数据,运用SBM(slacks based measure)模型和GML(global malmquist-luenberger)指数测算30个省市的动态绿色全要素生产率变化,运用门限回归模型和调节效应模型探讨金融业集聚和制造业集聚对科技创新成果和绿色全要素生产关系的门槛效应和调节效应。结果表明:1)科技创新成果对绿色全要素生产率的系数显著为正;2)金融业集聚对科技创新成果和绿色全要素生产率关系有正向调节和单门槛效应;3)制造业集聚对科技创新成果和绿色全要素生产率关系有负向调节作用;4)地方财政一般公共预算支出、人均居民可支配收入、外商投资对绿色全要素生产率具有显著促进作用。基于此,提出应关注科技创新成果与绿色经济发展的匹配度,注重数字金融的发展打破金融业的空间壁垒,引导制造业转向高质量集聚,实现财政资源在环保领域的合理配置,加强对外商投资环保监管。Study of impacts of technical innovation on green total factor productivity from perspective of industrial agglomeration is of strategic significance to promoting a coordinated development between technical innovation and green economy in China and keeping same pace between industrial development and environmental protection.This paper,based on 2008 to 2019 provincial panel data of Chinese provinces(cities),uses SBM model and GML indicator to estimate the dynamic changes of green total factor productivity in 30 Chinese provinces(cities),and applies threshold regression model and adjusting effect model to discuss the threshold and adjusting effects of financing&manufacturing conglomeration on technical innovative achievements and green total factor productivity.Results show a strikingly positive coefficient of technical innovative achievements on green total factor productivity,a positive adjusting and sole threshold effect of financing conglomeration on technical innovative achievement and green total factor productivity,and a negative adjusting of manufacturing conglomeration,and an outstandingly adjusting of local public budget,residents usable income per capita and foreign investment on green total factor productivity.This paper presents suggestions on focusing on their match between technical innovative achievements and green economic development,enabling digital financing to break the spatial barrier of financing,converting manufacturing to a quality conglomeration,properly allocating financing resources in environmental protection sector,and boosting supervision of foreign investment in environmental protection.
