Abstract
For achieving the sustainable development goals, green development has been raised to a high position for cities in China. The economic development in Northwest China is slow, the ecological environment is fragile, and the mineral resources are rich. Only through green development can we realize the comprehensive income of regional production development, rich life, and good ecology. This paper measures the green development efficiency of 30 prefecture-level cities in Northwest China by using DEA-SBM model of unexpected output, explores the differences and causes of green development efficiency from the perspective of time and space through convergence coefficient, coordination matrix, GIS, and other methods, and empirically tests the impact of industrial structure, technological progress, and other driving factors on green development efficiency by using panel Tobit model. The results show that, on the whole, the efficiency of green development in Northwest China is low, path dependence is serious and unbalanced, the coordinated development effect of different regions is weak, and the spillover effect of core urban agglomerations has not been effectively exerted; from the perspective of driving factors, economic development, population density, traffic situation, and education investment can significantly improve the efficiency of urban green development, and the second is that the proportion of industries significantly hinders the improvement of green development efficiency, while the impact of scientific and technological innovation is not significant. Based on the empirical results, this paper believes that the harmonious development of natural environment and economic society can be realized only by improving the coordinated development effect among cities, implementing the optimization and upgrading of industrial structure, introducing excellent talents, and promoting the technological upgrading.

In the 21st century, if China is to achieve high-quality economic growth and a winwin situation for ecological well-being, it must change its development model and take a green development path to promote a green economy [5]. erefore, it is important to evaluate the effect of green development from a quantitative perspective

Summary
Since the beginning of the 21st century, the ecological environment capacity and resource carrying capacity have gradually become the main factors restricting economic development. A green economy based on traditional industries, coordinated economic and environmental development, and market oriented has become an inevitable choice for China’s development strategy. British economist Pearce’s “Green Economy Blue Book,” published in 1989, first proposed the concept of a green economy. He believed that economic development must not be at the expense of environmental damage. The exhaustion of resources was never the cause of economic stagnation, and green development was a breakthrough in resources’ environmental constraints, transforming environmental advantages into development advantages, transforming the dynamic mechanism of economic growth, changing the way economic growth is focused, unifying economic growth, social development, and eco-friendliness to achieve highquality economic growth, and the coordination and fairness of society as a whole effective sustainable development. Green development is the era of China’s development, and it is a key move in the construction of ecological civilization
