Abstract

Abstract:

The problem of elevator retrofitting has restricted the smooth implementation of old neighborhood renovation in China and intensified the contradiction between the aging population and the growing demands of the people for a better life. Therefore， designing a new model to solve the problem of elevator retrofitting in old neighborhoods has become an important and urgent practical problem. Firstly， the traditional model of elevator retrofitting in old neighborhoods is analyzed， and on this basis， the project cooperation model of elevator retrofitting is improved and designed in old neighborhoods and a profitability model of the project is constructed from the perspective of social capitalists. Secondly， the two profitability functions of such projects and their variation laws have been obtained through differential analysis. Finally， Monte Carlo simulation is used to simulate the profitability of the project under this model， and the applicable intervals of key parameters are obtained. The results show that：（1） the amount paid by the residents for using elevators is a key parameter to ensure the profitability of the project， which is a prerequisite for the effective participation of the social capital party in the project. （2） Payments from residents for the use of elevators and government subsidies have a great influence on the functional form of corporate income. This shows that， on the one hand， a reasonable amount of residents' payment should be formulated to provide the precondition and motivation for the social capital party to participate in the project； On the other hand， the government should adjust the amount of residents' payment and government subsidies through discussion， so as to influence the functional form of enterprise income to ensure that the old residential area elevator project will ultimately achieve the results of enterprise profitability， residents' willingness and government satisfaction.A valuable reference for solving the problem of installing elevators in old residential areas is provided. All stakeholders can re explore and reach favorable cooperation under the new model， which to some extent helps to eliminate the hidden dangers that the inability to install elevators brings to the reconstruction of old residential areas in China.

Key words: old neighborhoods, elevator retrofitting, PPP, model design
