This study constructs the framework of regional ecological environment governance operation mode of “governance objective-governance power-governance subject-governance mode-governance object”. By constructing a comprehensive index of environmental regulation intensity and an index system of green economic efficiency，the eco-environmental governance performance and green development level of Beijing，Tianjin and Hebei “2+11” cities are measured. The following basic conclusions are drawn. The level of environmental regulation in Beijing-Tianjin-Hebei region has been continuously improving，showing an overall evolutionary characteristic of “convergence-differentiation-convergence”. From 2008 to 2017，the level of green development in Beijing-Tianjin-Hebei region has steadily improved. The whole region presents a “core-periphery” green economic pattern. The green economic efficiency of these cities of Beijing，Tianjin，Cangzhou and Tangshan is obviously better than that of other cities. Environmental regulation has a positive spillover effect on the green economic efficiency in Beijing-Tianjin-Hebei region. Science and technology innovation and regional industrial structure will both affect the regional green economic efficiency. However，the effectiveness of environmental governance in the three regions is still lagging behind that in the Yangtze River delta urban agglomeration and other regions，and a normalized mechanism of cross-regional cooperative governance has not yet been formed. To this end，this study from the expansion of green development space，to build a green governance system；According to local conditions，classify and implement policies to promote the transformation of the region to green and low carbon. To improve the ecological compensation mechanism，strengthen regional cooperative governance and other levels to put forward countermeasures and suggestions.
