Under the background that the concept of green development has gradually become the center of the reconstruction of the world economic order and global environmental governance.From adhering to the construction of ecological civilization,to energy reform,finally to the national strategy of "the combination of carbon peaking and carbon neutrality",China’s emphasis on environmental pollution and ecological environment balance has been always reflected.For a long time,we have been strongly aware that,in addition to the continuous advancement of the modernization process and the consistent updating of the technical system,the source of high-quality economic development in China is important to develop and focus on a road that balances steady economic development and ecological protection.After entering the new era of socialism with Chinese characteristics,the party and the country have made it clear that with the continuous improvement of China’s income level,the needs of people are gradually changing,the main contradiction has been transformed into the contradiction between the people’s growing need for a better life and the unbalanced development.A green ecological environment is an important part on the path of achieving a good life.Therefore,resolving the problem of environmental degradation has become one of the main contradictions in China’s economic development.Green development mainly refers to the process of transitioning from the massive growth that is highly dependent on mainstream energy input to reducing the input of nonrenewable energy and negative output of pollutant emissions.The essence of this process is to improve green total factor productivity.On the basis of total productivity,green total factor productivity takes into account resource and environmental constraints,and effectively measures the level of green economic development.Under the dual goals of economic transformation and pollution control,it is of great significance to explore a balanced development model that is compatible with environmental governance and green total factor productivity.In recent years,China’s environmental protection department has issued a number of governance plans and policy documents to solve the problem of environmental pollution,and the "new air quality standard" is an important part.Can the implementation of the "New Air Quality Standards" promote the growth of green total factor productivity while reducing the output of pollutants? Are the changes in green total factor productivity consistent in different cities in the face of "new air quality standards" ? In addition to directly affecting green total factor productivity,what is the main path for the "new air quality standard" to play its role? The above questions need to be explored from both theoretical and empirical aspects.This paper calculates the green total factor productivity of 283 cities from 2004 to2019 based on the SBM Super-Efficiency and Global Malmquist Luenberger index.Explore the impact of "new air quality standards" on urban green total factor productivity.In addition to the basic analysis,this paper explored the heterogeneity of the implementation effects of the "New Air Quality Standards".Then,proposed and verified three possible paths of "new air quality standard" on green total factor productivity.The research conclusions are as follows:(1)After the implementation of the "New Air Quality Standard",the green total factor productivity of urban will increase by about 0.028 units.(2)After the implementation of the "New Air Quality Standard".The order of coefficients is: Eastern Region>Western Region > Northeast Region;Mature city>Growth city>Regenerative city>Non-resource-based city;Central City>Non-Central City.(3)The "New Air Quality Standard" improves urban green production efficiency through green technology innovation,environmental protection administrative penalties and the promotion of industrial structure transformation. |
