Enterprise Technology Innovation Effect Of Environmental Regulation And China's Smog Pollution

Haze pollution with PM10 and PM2.5 as the main components frequently occurs in various cities in China for a long time and involves a wide range of areas.The hazy weather with large area has serious impacts on people's health and daily life.The externalities of environmental problems such as smog pollution make its governance depend largely on the formulation,implementation and supervision of government environmental protection policies.From the perspective of environmental policies of various countries,raising the standards of environmental governance and strengthening the enforcement of regional environmental policies are still the core means of environmental protection.The existing research on smog pollution rarely involves the technological innovation effect of environmental regulation under the spillover effect.The article holds that while environmental regulation directly reduces pollution,it also indirectly aggravates or reduces pollution through the technological innovation effect of enterprises,and the environmental regulation Of enterprise technological innovation effect is "follow cost effect" or "innovation compensation effect",which is related to the type,intensity and spillover of environmental regulation,which leads to the non-linear relationship between the enterprise technological innovation effect of environmental regulation and smog pollution.Therefore,under the threshold effect and the spillover effect of different types of environmental regulation,this paper studies the relationship between technological innovation effect of enterprises under environmental regulation and smog pollution.First,a theoretical model of the relationship between environmental regulation,technological innovation and smog pollution has been built on the basis of microeconomic theories such as production function at technical level,consumer budget constraint considering environmental regulation,and pollution function considering technical level.Secondly,it theoretically expounds the mechanism of environmental regulation on "following cost effect" and "innovation compensation effect" of enterprise technological innovation,and puts forward three propositions in this article.Finally,according to the theoretical needs,various types of interaction items between environmental regulation and technological innovation of enterprises are introduced.By using the spatial Dubin model(SDM),a corresponding econometric model is constructed for empirical analysis under the threshold of environmental regulation to verify the relevant theoretical propositions.The main conclusions drawn from the research are as follows:(1)The spillover effect exists in environmental regulation,technological innovation in enterprises and smog pollution.(2)The impact of environmental regulation with different types and intensities on the effect of technological innovation is different,resulting in a nonlinear relationship with the smog pollution.The technological innovation effect of enterprises with market-oriented environmental regulation and the smog pollution showed a "inverted U-shaped" development relationship.That is,the higher investment in environmental pollution control is more conducive to the occurrence of enterprise technology "innovation compensation effect";the market-based and mandatory Under the threshold conditions,the technological innovation effects of environmental regulation showed "U-shaped" and "N-shaped" development relations with the haze pollution respectively.This shows that in addition to the market-based environmental regulation of environmental pollution control investment,the intensity of the other two environmental regulatory tools Too large are not conducive to enterprise technology "innovation compensation effect" to play,but strengthened the "follow the cost effect",thereby aggravating the pollution.(3)Decomposition of space effect reveals that market-based environmental regulation has "path-dependent effect" on the neighboring areas of geographical and economic factors in the region,that is,the intensification of market-based environmental regulations in the neighboring areas will exacerbate smog pollution in the region.However,there is no "path-dependent effect" between the compulsory environmental regulations and the neighboring areas.Compulsory environmental regulations make the neighboring areas have a "radiation effect" on the region,thereby reducing smog pollution in the region.Accordingly,the enlightenments are:(1)The governance of smog pollution should promote the joint governance of all regions under the control of the central government to avoid the pollution deterioration caused by such factors as technology spillover and shadow economy.(2)To enhance the intensity of market-oriented environmental regulation and improve the current unreasonable collection of sewerage charges so as to make the establishment of levying standards more standardized,market-oriented and scientific;(3)The implementation of compulsory and marketbased environmental regulations should Remain within a reasonable threshold for enabling "innovative compensation effects" of enterprise technology to play.In promoting environmental regulation toward market-oriented at the same time focus on supporting the use of various environmental regulatory tools.The increasingly serious smog pollution in various regions has a bearing on people's health and interests as well as the technological innovation effect of China's urban green and sustainable development and environmental regulatory policies and reflects the perfection of government standards.Rather than smog pollution is a major test before the local governments,it is better to say that it is a more complete system of mechanisms for environmental governance at all levels of government in China.
