Research On The Cost Sharing Compensation Model And Mechanism Of Adding Elevators In Existing Residential Buildings

In the 1980s and 1990s,in order to solve the housing shortage of urban families,China built a large number of 4-6-storey non elevator houses.The comprehensive safety,convenience and comfort of such houses have not matched the conditions required by the current home-based care,It is of great significance to promote the work of adding elevators in existing residential buildings to improve the existing quality of life of the elderly.Support for the addition of elevators has been included in the government work report for three consecutive years,and many local governments have also launched policies and guidance on the addition of elevators.However,due to the difference of interest demands of residents on different floors and the difficulty in unifying opinions on the cost sharing scheme,it is difficult to add elevators.In addition,in the process of adding elevators,there is a lack of effective communication and cooperation among stakeholders,and there are problems in the source of funds,investment and financing subjects,which make the work of adding elevators unable to be carried out in depth and need to be solved urgently.In view of the above problems,this study has done the following work:Based on the life cycle perspective,this paper analyzes and identifies the stages of the existing residential elevator project,divides it into three stages:preparation,transformation implementation and maintenance operation,and expounds the main work contents of each stage in detail.This paper introduces the life cycle cost theory,identifies and quantifies the life cycle incremental cost and incremental benefit of the existing residential elevator project based on the systematic principle,hierarchical principle and incremental principle,and determines the life cycle cost estimation method of the existing residential elevator project based on the capital time value theory.Through random interceptive interviews with the residents of the community planning to add elevators,it is found that the residents of different floors have different interest demands for adding elevators:high-rise residents,especially the elderly,have strong willingness to add elevators for safety and convenience;Most middle-level residents hold a wait-and-see attitude because of the proportion of investment;However,the low-rise residents are not willing to add elevators,and even resist to add elevators from various angles.Based on the interview results and conflict management theory,from the perspective of the interest demands of residents on different floors,this paper establishes a theoretical model of cost sharing compensation for adding elevators in existing residential buildings under the balance of interests,and obtains the cost sharing compensation scheme among residents on different floors,which is verified by the survey data of a community in Xi'an.In order to effectively solve the financial problem of adding elevators to existing residential buildings,from the perspective of stakeholders,a diversified,market-oriented and normalized cost mechanism is established,which is elaborated from two dimensions of cost raising channel and cost payment mode,and relevant suggestions on the implementation of adding elevators are put forward.
