Abstract
In order to investigate the formulation of appropriate environmental regulations in construction and demolition waste (CDW) recycling, this paper establishes a CDW recycling decision-making system consisting of a contractor, a developer, and the government and analyses the decision-making results and influencing factors of the various stakeholders. Three different types of environmental regulations have been considered in the model: (i) no regulation, (ii) incentive regulation, and (iii) punitive regulation. The research shows that the incentive regulation offers the constructor greater incentives to recycle CDW and yields higher profits for members of the system, and however, when recycling is very costly and CDW is highly damaging, punitive regulation should be implemented, as the incentive regulation leads to lower social welfare. In addition, governments should be more cautious when adopting incentive regulation, because social welfare may be negative under this condition whereas there is no such possibility under the punitive regulation.
Highlights
With the rapid development of China’s urbanization process, the construction of housing and municipal infrastructure has accelerated, which meets the needs of economic development and the public use and generates a large amount of construction and demolition waste (CDW)
Compared to the incentive regulation, the punitive regulation yields a higher social welfare only when CDW recycling is costly and the degree of damage is high. erefore, we get a similar enlightenment as Proposition 6: the government should fully consider the degree of damage and recycling cost when formulating environmental regulation
Compared with the punitive regulation, the recycling amount under the incentive regulation is larger, which suggests that the incentive regulation can better promote CDW recycling
Summary
With the rapid development of China’s urbanization process, the construction of housing and municipal infrastructure has accelerated, which meets the needs of economic development and the public use and generates a large amount of construction and demolition waste (CDW). Under the social background of ecological construction and sustainable urban development, the Chinese government began to attach greater importance to CDW recycling by issuing diverse environmental regulations in recent years. (3) Under different environmental regulations, how do the government, constructor, and developer determine their optimal decisions? To the best of our knowledge, this paper makes the first attempt to compare the implementation performance of different environmental regulations in consideration of the dynamic impact of various stakeholders in the waste recycling process. It is anticipated that this study will enrich the existing body of knowledge on CDW recycling and provide a theoretical basis for the formulation and optimization of government regulations.
