The Measurement And Sharing Mechanism Of The Comprehensive Benefit Of Old Community Renewal

In recent years,the continuous promotion of the renewal of old communities in our country has led to the emergence of a large number of renewal projects for old communities.It has been continuously bringing positive effects as expanding domestic demand,optimizing urban renewal and transformation of development and construction methods,and promoting highquality economic development.Old community renewal has become an important livelihood project in China.These projects have brought a large number of comprehensive benefits such as economic,social and environmental benefits to the society,but the evaluation of benefits mostly stays in qualitative research,lacking quantitative benefit measurement methods.It is difficult to support the establishment of a comprehensive benefit sharing mechanism and attract more social intervention to transform.In order to solve the above problems,this paper constructs the research framework of the comprehensive benefit measurement and sharing mechanism of the old community renewal by introducing the emergy analysis method and the Shapley value method.First,26 comprehensive benefits of the old community renewal are identified and divided into three categories:economic benefits,social benefits and environmental benefits,through the sorting and analysis of existing policies and literature research combined with the survey to the participating subjects.Then,the emergy analysis method is used to build a comprehensive benefit measurement model for the old community renewal.The model is to calculate and evaluate the comprehensive benefit content on the basis of emergy.Next,the Shapley value method is used to construct a benefit sharing model,in which three correction factors of “policy support”,“cooperative relationship” and “exploitable space” are introduced to revise the model.By the revised benefit sharing model,benefit content under different renewal modes can be calculated and benefit sharing mechanism for the renewal of old communities is proposed.Finally,the case study finds that the comprehensive benefit value of the old community renewal reaches2.35E+19 sej(equals to 48 million CNY),accounting for 74.1% of the investment value of the renewal project.Under the "Government-led implementation" renewal mode,the benefit sharing value between government,residents,and participating enterprises can reach 6.02E+18sej,4.56E+18 sej and 6.54E+18 sej(approximately 9.71 million CNY,7.36 million CNY,10.5million CNY).Under the renewal mode of "Government guidance-enterprise implementation",the government’s benefit sharing energy value can be further increased by 5.9%.To achieve the comprehensive benefit sharing of the old community renewal,it is necessary to implement the empowerment mechanism,the realization mechanism,the circulation mechanism and the guarantee mechanism,four types of benefit sharing mechanisms,for the renewal of old communities.This article introduces the emergy analysis method into the research on the renewal of old communities,expands the application scenarios of the emergy analysis method,and enriches the research methods of the transformation of old communities.It also provides a relatively novel idea for the relevant research on comprehensive benefits of the renewal of old communities.At the same time,the benefit measurement method and benefit sharing mechanism proposed in this article will help the government absorb social capital and strengthen public participation,and help residents have a more comprehensive and detailed understanding of the positive effects of old community renewal activities on their own living environment and social environment.For relevant enterprises,this can improve the quality of the renewal of old communities and improve the project yield and renewal efficiency.This paper will be helpful for promoting the realization of a major national strategy for the renewal of old communities.
