When we talk about urban renewal, the concept of "sunk costs" in economics can't help but come to mind.
Sunk costs, which are those costs that have already been incurred and cannot be achieved.
In the context of urban renewal, many people may see the renovation of old neighborhoods as a sunk cost, but this is far from the case.
In particular, the issue of installing elevators in old residential areas covers economic and sociological principles that are far more complex than they seem on the surface.
First of all, the installation of elevators in old communities is not a simple physical addition, but a complex social project.
It involves not only technical issues, but also major issues related to the interests of residents, urban planning and social development.
In the context of China's rapid urbanization,The existence of old residential areas actually carries the historical context of urban development, and they have witnessed the rapid expansion of the city from the early stage to the current mature development.
However, this problem is not just a social problem, it also involves the theories of "public goods" and "externalities" in economics.
Public goods are characterized by non-competition and non-exclusivity, and the installation of elevators fits this definition exactly.
From an economic point of view, the construction and use of elevators creates positive externalities, i.e., benefits to residents who are not directly involved in the payment.
The existence of this externality makes the installation and maintenance of elevators a typical collective action problem.
Further, it involves urban renewal and the rebalancing of the real estate market.
From the perspective of microeconomics, the renovation of the old community is actually an adjustment of market supply, which not only enhances the value of the house itself, but also has an impact on the surrounding real estate market.
By improving the living environment of the old community, the population density problem in the urban center can be alleviated to a certain extent, and at the same time, it also provides a new impetus for the balanced development of the city as a whole.
In addition, the elevator installation project also reflects the modernization of urban governance and community management.
It requires consultation between residents, communication between the people and the balance of multiple interests, and is the embodiment of a new type of urban governance model.
Finally, the seemingly unrelated question of this article is: in the future, with the development of technology, it is possible for us to see a completely different way of renovating old communities
For example, the use of advanced building technology, or the complete redesign of living spaces.
This question actually points to the future trend of urban development. With the advancement of technology, such as the development of 3D printed buildings or modular buildings, it is entirely possible that we will see more efficient, economical and environmentally friendly ways of urban renewal.
This will not only solve the current problems faced by old communities, but may also bring about fundamental changes in the urban living environment.
Such changes will further affect the economic structure of the city, the lifestyle of residents, and even the social and cultural pattern.
Therefore, in addition to the practical significance of the renovation of old communities, we should also focus on the broader impact that may be brought about in the future.
