Green Technology Acquisition and Air Pollution——The Analysis of Efficient Market and Effective Government
Under the background of ecological civilization construction,green technology acquisition is an important market means for enterprises to make up for the limitations of their environmental protection technology.Based on green patent transfer data,it examined the impact of green technology acquisition on air pollution in Chinese cities.The results show that green technology acquisition can reduce air pollution significantly,but this effect is heterogeneous across acquisition motivations and technology categories.Focusing on the direct use value of green technology acquisition and the derived value of knowledge spillover,it is found that green technology acquisition can restrain air pollution through the industrial structure upgrading effect and green knowledge expansion effect.Further research finds that from the perspective of pollution reduction,whether there is a synergistic effect between efficient market and effective government is related to government environmental regulation measures.Command-and-control environmental regulation and green technology acquisition can synergistically suppress air pollution,while market incentive environmental regulation and green technology acquisition do not show significant synergistic effect in reducing air pollution.It not only expands the application boundaries of open innovation theory and technology gap theory in green technology acquisition from the perspective of pollution reduction,but also provides theoretical support for the rational allocation of market means and administrative means under the pollution reduction target.
