摘要:

加装电梯难题制约了我国老旧小区改造的顺利实施,加剧了人口老龄化与人民日益增长的美好生活需要之间的矛盾。因此,设计新模式以解决老旧小区加装电梯难题就成为了重要且迫切的现实问题。首先,本文对老旧小区加装电梯的传统模式进行解析,在此基础上改进、设计了老旧小区加装电梯的项目合作模式并构建了社会资本方视角下的项目盈利能力模型。其次,基于微分分析得到此类项目的两种盈利函数及其变化规律。最后,利用蒙特卡洛模拟对该模式下项目盈利能力进行了仿真,得到了关键参数的适用区间。结果显示:(1)居民有偿使用电梯付费额是保证项目具有盈利空间的关键参数,居民付费额达标是社会资本方有效参与项目的前提条件。(2)居民有偿使用电梯付费额与政府补贴力度对企业收益的函数形式具有显著影响。结果表明,应制定合理的居民付费额,为社会资本方参与项目提供前提条件和动力;政府应通过商讨调节居民付费额和政府补贴力度,从而影响企业收益的函数形式,以确保老旧小区加装电梯项目最终达到企业盈利、居民愿意、政府满意的结果。本文为老旧小区加装电梯问题的解决提供了有价值的参考,各利益相关方在新模式下能够重新探索、达成有利协作,有助于消除无法加装电梯给我国老旧小区改造带来的隐患。

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.
