摘　　要：乳业作为食品行业中最长产业链,事关国计民生,肩负绿色低碳可持续发展的重任。本文基于2008―2021年中国28个省份的面板数据,采用超效率-基于ε的度量模型和全球马尔奎斯特-卢恩伯格指数测度乳业绿色发展水平。在厘清乳制品产业集聚的环境效应形成机理的基础上,构建基准回归模型和中介效应模型系统地检验乳制品产业集聚对乳业绿色发展的影响效果和作用机制。研究发现:1)乳制品产业集聚能显著促进乳业绿色发展,这一结果在更换绿色发展度量指标、改变聚类层级、工具变量估计和基于异方差构造工具变量方法等稳健性和内生性检验后仍成立;2)机制检验表明,乳制品产业集聚通过促进技术创新和信息化水平,对乳业绿色发展发挥积极作用;3)分组回归结果表明,对于未实施千万吨工程和拥有较低良好生产规范的省份,产业集聚对乳业绿色发展的正向激励作用更明显。本文还根据研究结论就如何推动乳业产业链融合集群发展和绿色发展,提出了相关政策建议。The dairy industry,with the longest supply chain in the food sector,plays a crucial role in national welfare and people’s livelihood and has significant responsibilities for green,low-carbon and sustainable development.Based on panel data from 28 Chinese provinces between the years 2008 and 2021,this paper assessed the green development of the dairy industry using the super-efficiency epsilon-based measure(EBM)model and the global Malmquist-Luenberger(GML)index.On the basis of clarifying the formation mechanism of the environmental effect of dairy industrial agglomeration,this paper established benchmark regression models and intermediary effect models to examine the impact and mechanism of industrial agglomeration in the dairy industry on its green development.It was found that(1)industrial agglomeration significantly promoted the green development of the dairy industry,and this finding still holds after robustness and endogeneity tests,such as replacing the green development metrics,changing the clustering level,performing instrumental variable estimation and using heteroscedasticity-based instrumental variable methods;(2)the mechanism test showed that industrial agglomeration played a positive role in the green development of the dairy industry by improving the level of technological innovation and informatization;(3)group-wise regression results showed that for provinces that had not implemented the“ten-millionton project”with low levels of good manufacturing practices,industrial agglomeration exerted a more positive effect on the green development of the dairy industry.Drawing on these findings,the study offers policy recommendations to advance the integration of industrial clusters and the green development of the dairy industry chain.
