Abstract
Since 1 January 2021, China has banned nondegradable disposable straws in the catering industry. To promote the enforcement of the ban of plastic straws and improve the relationship between economic development and environmental protection, based on the evolutionary game method, this paper constructs the game model from the supply side and the demand side, respectively. Subsequently, through the dynamic equation, stable system evolution strategy is obtained. Furthermore, simulation is conducted to test the influence of the main parameters in the model on the evolution of system strategy. The results show that (1) the change of the government strategy mainly depends on its regulation costs and revenue, while the production strategy of a company is affected by the government and consumer strategies. (2) From the perspective of enterprise supply, government subsidies can promote technological innovation and develop new plastic straw substitutes. However, government penalties have little effect on violating enterprises. In addition, from the perspective of enterprise demand, with the collaboration of enterprises and consumers, it is easier for enterprises to carry out technological innovation. (3) Consumer acceptance of the substitutes for disposable plastic straws as well as online comments have a decisive influence on the enterprises’ selections for research and development (R&D) strategies.
Highlights
At present, plastics are widely used in various fields of our life, but their irregular production, utilization, and disposal cause waste of resources and pollution of the ecological environment and even affect public health
This paper studies the plastic straw ban at first, determines the crawling content and time range of online comment data based on the policy content and analyzes the emotion of comments
The results showed that a single-use plastic ban would decrease plastic marine pollution in the European Union (EU) by 5.5% which equated to a 0.06% decrease globally
Summary
Plastics are widely used in various fields of our life, but their irregular production, utilization, and disposal cause waste of resources and pollution of the ecological environment and even affect public health. To reduce plastic pollution and protect the environment, it is necessary to study the relationship between the production strategy of straw companies, consumer use strategies, and government regulation strategies so as to provide a basis for the formulation and implementation of the company’s production plan. This paper focuses on how to guide enterprises to carry out technological innovation, change production strategies, and promote them to produce plastic straw substitutes with good functionality and environmental protection. At the same time, based on the government–enterprise model, the government–enterprise–consumer model introduces the factors of consumer acceptance and network comments on plastic straw substitutes and discusses the changes of the enterprise production strategy as well as the impact of government measures, consumer acceptance, and network comments on the production strategy when enterprises consider their own production capacity and consumer demands. The structure of the paper is organized as follows: Section 2 is literature review, Section 3 introduces research framework of this paper, Section 4 introduces global regulations on plastic and analyzes the ban of plastic straws, Section 5 uses online review data to analyze consumers’ emotional tendencies towards the new “plastic ban” and plastic straw substitutes, Section 6 constructs two game models of a multi-stakeholder strategy and simulation analysis under the plastic straw ban, Section 7 is the results and discussions, and Section 8 is the conclusions
