The problem of urban spatial differentiation with bet365 apuestas areas as the main body，It is urban sociology at home and abroad、A hot topic of long-term concern in urban geography and other disciplines。Especially for megacities with a population of tens of millions，How to leverage the dual power of a promising government and an effective market，Strengthening the leading role of urban planning，Make it as fair as possible、Multiple、Tolerance、Harmonious urban living space structure，To promote the all-round development of people、Social fairness and justice，Prevent major social risks，Has outstanding strategic significance。

　　Create a high-quality living bet365 apuestas

Some megacities in Western countries are in the process of urban renewal，Due to improper planning and spatial design of urban bet365 apuestas areas，Resulting in some originally good bet365 apuestas areas，Become a concentrated outbreak place of urban social problems。Severe spatial repulsion、The reality of bet365 apuestas isolation，It goes against people’s desire for a better life in the city。

After more than 20 years of housing market reform，Residential differentiation also occurs in some of my country’s megacities。To this，Domestic scholars have conducted research using population data。But in terms of a specific megacity with thousands of residential areas，What is the relationship between spatial differentiation of residential areas and bet365 apuestas？Different planning and design solutions，What kind of impact will it have on the actions of people in the community？For residential communities with different degrees of differentiation，What kind of differentiated planning strategy should be adopted？What kind of bet365 apuestas is fair and inclusive and good planning？For these questions，We may not necessarily understand it very clearly。

"The Fourteenth Five-Year Plan for National Economic and Social Development of the People's Republic of China and the Outline of Long-term Goals for 2035" emphasizes，Adhere to the path of new urbanization with Chinese characteristics，Deeply promote the new urbanization strategy with people as the core，Optimizing and improving the functions of central urban areas in megacities，Improving the livable and business-friendly functions of large and medium-sized cities，Enable more people to enjoy a higher quality of urban life。Comply with the laws of economic and social operation of megacities and the laws of urban renewal，In objective evaluation of the social impact of urban bet365 apuestas、On the basis of clarifying the dynamic process and level of spatial differentiation in residential areas，Continuously optimize existing urban bet365 apuestas plans and strategies，Minimize the isolation or spatial polarization of urban residential space，Creating fairness、Tolerance、Multiple、Colorful high-quality living community，It is a new stage of development for my country’s megacities、Implement the new development concept、Major issues that require great attention in the process of building a new development pattern。

　　Beware of poverty agglomeration and bet365 apuestas exclusion from residence

In our country, we are fully entering into the pursuit of high-quality development、High quality life、A new development stage of high-efficiency governance，For more accuracy、Answer the above question in more detail，We are delighted to see the book "Social Impact Assessment of Urban bet365 apuestas" (China Social Sciences Press, October 2020 Edition) completed by Zhang Jun based on years of research，Officially published。The book is divided into 11 chapters，The research objects cover 7,000 residential areas in Shanghai，Utilizing big data、Questionnaire Survey、Various research methods such as field surveys，Planning and spatial differentiation for urban residents、Community recognition、Community Participation、The relationship between community conflicts，And the social influence mechanism of urban bet365 apuestas、Evaluation mode、Evaluation methods, etc.，Carry out all aspects、Systematic research。The author intends to create a continuous optimization strategy for urban bet365 apuestas、Innovative grassroots community governance model、An action guide for building a high-quality, inclusive and harmonious residential community。

According to the book，Different types of bet365 apuestas areas have different degrees of differentiation，High degree of differentiation in low-level bet365 apuestas areas，May lead to concentrated bet365 apuestas poverty and social exclusion，It should arouse the alarm of government departments and society。The author uses big data to point out，With the continuous expansion of cities and the in-depth market-oriented reform of housing，The rapid agglomeration of low-income bet365 apuestas space in Shanghai。In the past ten years, Shanghai’s low-level bet365 apuestas space has differentiated faster than high-level bet365 apuestas space，The degree of differentiation in high-level living spaces has decreased。At the same time，Low-level bet365 apuestas areas located in urban suburbs and old communities in central urban areas (mainly migrant population) have higher community identity。Under the effect of the poverty reproduction mechanism of the living environment space，These low-level bet365 apuestas areas are more likely to cause poverty agglomeration and social exclusion。This is a valuable discovery。

Urban bet365 apuestas has comprehensive social impact，And has a relatively complex internal mechanism。The social impact of differentiated urban residential planning，Not only reflected in the social differentiation of living space，It is also reflected in community recognition、Community Participation、Community conflicts and other areas，And the community location、Scale、Density (three levels of residential density)、Spatial mixing degree, etc.，Is the main variable factor that produces the social impact of bet365 apuestas。From the perspective of interaction mechanism，Social influence mechanism of urban bet365 apuestas，Mainly includes spatial planning of residential areas，The degree of spatial differentiation that affects residential areas；Differences in bet365 apuestas，Influence the role of neighborhood effect；Differences in urban residential areas，Have a direct impact on community creation；bet365 apuestas，Directly affects residents’ quality of life。

　　Building a grassroots bet365 apuestas governance community

Social Impact Assessment of Urban bet365 apuestas，It is a professional evaluation method system that is different from general social impact evaluation，We must stand in line with China’s national conditions、Perspective of meeting people’s needs for a better life，Construct and practice it。Proposed by the author，Urban bet365 apuestas evaluation procedures should include prior evaluation、Evaluation during the event、“Full process evaluation” of post-event evaluation。The social impact assessment procedures for different types of bet365 apuestas are not exactly the same，There should be some focus and differentiation。Pointed out in the book，Important methods for social impact assessment of urban bet365 apuestas，Should reflect “emphasis on procedures over indicators、Open source、High operability under openness” with the feature of “upgradability”，Adopt classification、Open、Key social impact assessment model for bet365 apuestas。At the same time，The author selects some representative bet365 apuestas schemes，Evaluation process and methods according to design，Carry out empirical evaluation and test。

The author thinks，Megacity Science、Fair、Inclusive bet365 apuestas，To promote the inclusive development of urban society、Fair development、Safe development and harmonious development play an important role，Especially the planning of low-level residential areas has huge potential for continuous optimization and improvement。The author proposes that domestic large and medium-sized cities proactively carry out social impact assessment of urban bet365 apuestas，And in view of the contradictions and outstanding problems faced by low-level residential areas，Propose countermeasures and suggestions to improve and improve bet365 apuestas。Specifically including improving transportation convenience and spatial connectivity、Equipped with better education, medical, greening and other supporting facilities construction、Reduce the floor area ratio of residential areas、Appropriate residential area size, etc.，To protect residents’ employment、Interaction、Opportunities to integrate into the city，Increase active recognition，Enhanced interaction、Resolving conflicts，Actively build a grassroots social governance community that is co-constructed, co-governed and shared。

The social impact assessment of urban bet365 apuestas has features that can be learned、Can be copied、Distinctive characteristics that can be promoted，More large, medium and small cities have the feasibility of carrying out equivalent evaluation activities。For this，The author uses theoretical research、Literature materials and empirical evaluation，Attached at the end of the book is the "Social Impact Assessment Manual for Urban bet365 apuestas"，Form a set of universal evaluation procedures、Methods and indicator systems，Provides a guidance tool for large and medium-sized cities across the country to independently carry out evaluation work，Also continuously optimize urban bet365 apuestas solutions for large and medium-sized cities，Indicated the direction and path。
