Trade integration is one of the manifestations of national integration，Traditional international trade theory believes that the impact of trade integration on the environment has a scale effect、Structural effects and technical effects。Unlike the trade between the country，The administrative division Bet365 lotto review faced by the integration of the country and region in the country、The relatively small differences in policy management and cultural differences，Regional integrated effect on environmental pollution is easier to observe。The active impact of regional integration on environmental governance has at least the following aspects。

First，Regional integration is conducive to the marketization of resource elements，Improve the efficiency of the use of resource elements，Reduce the cost of environmental protection technology transactions，Promoting the promotion and application of energy conservation and emission reduction technology。Integration of public services and transportation networks improves the sharing of public resources，Reduce the internal and external commuting distance and enhance the economic connection between the region，Reducing energy consumption and is conducive to energy saving and emission reduction。Industrial integration between regional industries is conducive to the professionalization of regional division of labor，Improve the space allocation efficiency of resources and industries，The scale economic effect and various overflow of pollution control。Policy management coordination in the process of regional integration continues to increase，Joint governance such as similar environmental regulations and pollution will be conducive to joint emission reduction。

Second，Regional integration is the process of gathering and decentralization of various elements and industries in space，The change in the degree of density of economic activities directly affects the demand for energy consumption and pollution emissions。The space concentration of economic activities will cause expansion of the output scale，A large -scale pollution effect，But economic agglomeration has various positive promotion effects on environmental quality，Give full play to the scale economy and various overflow effects of pollution governance，If the concentration of an enterprise is conducive to the centralized treatment of pollution，At the same time, the cost of pollution bet365 best casino games treatment of the enterprise can also be shared。Economic gathering is conducive to the sharing of gathering、matching and knowledge overflow effect，Improve the professional level of corporate pollution treatment，At the same time, it is also conducive to the centralized supervision of environmental protection departments and mutual supervision between enterprises。

third，The changes in the space economic structure in the process of regional integration will cause changes in energy efficiency and pollution emission demand，Different spatial economic structures and spatial tissue forms have different environmental effects。Regional integration will reduce the degree of fragmentation inside the city，Improve the compactness and connection between the internal sectors of the city。and optimize the structure of the internal space of the city，It is conducive to improving energy use efficiency，Improve the ecological environment of the city。Cancer is closely related to the attributes of land functions and economic activities and output density，Different land functions have different environmental effects。Compared to low -density decentralized cities，Compact cities with diversified land functions are more conducive to improving air quality。Land function and its spatial layout directly determines the spatial trajectory of human economic activities，The continuity of the land function in space has improved the internal and external connections of the city。

　　The main path for regional collaborative emission reduction

First, make full use of market integration energy saving and emission reduction effects。Current，China's environmental governance method is mainly administrative means，The market as the basic tool for resource allocation，It is the main direction of future pollution governance。This is necessary to promote the Yangtze River Delta area、The market integration process of Beijing -Tianjin -Hebei and the Guangdong -Hong Kong -Macao Greater Bay Area，Make full use of market integration to promote the dual policy bonus of regional market integration and regional collaborative emission reduction。Improve the market system of domestic bet365 best casino games products and factors resources，Accelerate the product market of key areas、Integrated process of factor energy market，Including raw materials、New Energy、Public Service、Finance、Technology、Traffic、Tourism and other key industries，Enhance the optimization effect of the integration of various industries on the configuration of factor space。Actively explore the new method of market -oriented pollution governance，Enhance the role of financial markets on pollution technology research and development and pollution governance，Actively develop green credit、Carbon Finance、Green Futures、Green Fund and other new products。Promoting the market -oriented reform of resources and energy price，Electricity、Coal、Petroleum、Minerals and other industries are key areas。Monetization of pollution emission rights，Constructing pollution emissions and energy trading markets at the national level，Determine the initial distribution right quota of pollution emissions at the regional level，Give full play to marketization of emission reduction incentives for economic entities。

Second, strengthen the emission reduction effect of micro -enterprises in the process of regional integration。Enterprise is the main body of economic activities and pollution emissions，It should play an emission reduction role in the process of regional integration。Current，The main body of pollution control in China is still local governments at all levels，Enterprises only pay attention to whether their environmental protection meets the standard，Low the willingness to participate in regional collaborative emission reduction。This will encourage enterprises to carry out cross -regional cross -industry technological innovation and environmental cooperation，Encourage private capital to participate in public pollution control projects，Accelerate the industrialization development of environmental pollution governance，Establish a government and enterprises、Input of environmental protection governance and environmental protection technical cooperation Bet365 lotto review between enterprises across regions、Risk sharing mechanism，Fully stimulates the enthusiasm of enterprises to participate in regional collaborative emission reduction。Establish a cross -regional enterprise cooperation development investment fund，Support the development cooperation of environmental protection technology across regions。Give play to the role of pollution governance of large enterprises，Strictly require large enterprises to fulfill the obligation to reduce emission reduction，Forced required key enterprises to disclose pollution emission information，Accept social supervision。Implement the pollution discharge credit collection system for key enterprises，Use environmental credit information as a variety of qualification review、Enterprise financing and obtaining the front conditions of the green guidance fund。

Third is the public interest based on collaborative emission reduction，Establish global consciousness of pollution governance。Under the incentive system of fiscal decentralization and official promotion，Local governments take their own interests to maximize their own interests as the main goal，Local officials may tend to adopt localized protection policies for local public interests。So，Collaborative emission reduction between regions needs to build a foundation that meets the public interests of the whole region，The realization of this foundation depends on the integration of regional economy，Economic integration is the basis for mutually beneficial and win -win between regions。This is necessary to form a consciousness of co -prevention and co -governance on the issue of dealing with global pollution，A goal with global public benefits，Carry out joint pollution treatment。Constructing a cross -border pollution source accounting system，Clarify the responsibility for governance of cross -border pollution in various places，It to weaken the negative incentive of local governments for cross -border pollution control。At the same time，Unified environmental protection standards in various places as soon as possible，Cross -ground bet365 Play online games transfer to prevent pollution。

Fourth is to fully study and judge and use the energy -saving and emission reduction effects optimized by space structure。Regional integration process can be regarded as resetting of regional space economic structures，Different spatial structures have different energy consumption and emission requirements。The changes in the regional space structure are accompanied by the population and industry、Traffic Network、Land function、A series of changes in urban residence balance。Strengthening spatial management is an important content for refined management，It is a new idea to achieve energy conservation and emission reduction by optimizing the regional spatial structure。First，Strengthen the concept of energy conservation and environmental protection in regional and urban planning，Construct a energy -saving and environmentally friendly urban internal space structure。Traditional urban landscape and architectural design more concerned about the aesthetics and energy -saving and environmental protection indicators of local urban space，Ignoring the environmental effect of the overall space layout of the city，Especially land function、Population and industrial space layout、Environmental effects of different cities such as transportation road network layout，and the energy efficiency and pollution emission requirements generated by the associated combination of these space forms。Therefore, the energy consumption and pollution emissions needs of different space structures must be judged in advance。Next，Pay attention to the environmental effect of regional space network structure。With the rise of urban agglomeration economy，The economic connection between cities is increasingly close，Urban development shows a network trend。Different control and influence of different cities in urban networks，Cities at important urban networks can gather more factor resources，It is conducive to improving the factor circulation efficiency of the entire city's network channel，Give full play to economic agglomeration and regional professional energy saving and emission reduction effects。Visible，Multi bet365 best casino games -central cities structure is more helpful to improve energy -saving and environmental benefits in the region compared to the single central city structure。
