选取中国30个省份为样本，构建数字经济与制造业绿色转型发展评价指标体系。运用耦合协调度模型测度了数字经济与制造业绿色转型耦合协调发展水平，并分析了动态演进、地区差异和空间效应。研究表明：2011—2020年我国数字经济与制造业绿色转型发展耦合协调度呈上升趋势，并存在明显的地区差异性；核密度显示全国以及东部、中部、东北地区数字经济与制造业绿色转型发展的耦合协调度存在明显的两极分化现象；Dagum基尼系数显示四大经济区域耦合协调度地区差异呈缩小趋势，地区差异主要来源于区域间差异；莫兰指数显示数字经济与制造业绿色转型发展的耦合协调度具有明显的空间效应。

This paper selects 30 provinces in China as samples to construct an evaluation index system for the development of digital economy and green transformation of manufacturing industry.The coupling coordination model is used to measure the level of coupling and coordinated development of digital economy and green transformation of manufacturing industry,and the dynamic evolution,regional differences and spatial effects are analyzed.The results show that from 2011 to 2020,the coupling and coordination degree of China’s digital economy and manufacturing green transformation and development showed an upward trend,and there were obvious regional differences.The kernel density shows that there is an obvious two-level differentiation in the coupling and coordination degree of digital economy and green transformation and development of manufacturing industry in eastern,central and northeastern regions of China.The Dagum Gini coefficient shows that the regional differences in the coupling coordination degree of the four major economic regions show a decreasing trend,and the regional differences mainly come from the regional differences.The Moran index shows that the coupling and coordination degree of digital economy and green transformation and development of manufacturing industry has obvious spatial effect.
