Water-Saving Technology Development and Collaboration Strategies for High Water-Consuming Enterprises—Game Research Under Water Resource Tax Regulation
Implementing water resource tax policies and enhancing the level of water-saving technology in high water-consuming enterprises are crucial paths to developing water-saving industries and building a water-saving society.However,how government resource regulation policies affect the water-saving technology cooperation and R&D strategies among high water-consuming enterprises remains to be thoroughly explored.In light of this,it constructed non-cooperative R&D decision,two-stage R&D shared incentive cooperation decision,and fully collaborative R&D decision for enterprise water-saving technology under the background of water resource tax,based on differential game theory.Through these strategies,it explored the time evolution trajectory of enterprises'equilibrium water-saving volume and technology level,and conductd a comparative analysis of enterprises'equilibrium profits.Furthermore,it utilized the Rubinstein bargaining model to allocate the profits generated by water-saving technology and conducted a simulation analysis and discussion for high water-consuming enterprise A in the pilot area of water resource tax.The results show that under the non-cooperative strategy,there is room for Pareto efficiency improvement in enterprises'decisions;while the R&D incentive strategy significantly enhance enterprises'investment in the development of water-saving technology,improve the maturity of water-saving technology,and increase enterprise profits.The degree of effort in water-saving technology R&D is positively correlated with the proportion of profit distribution,and a reasonable profit distribution mechanism is crucial for ensuring continuous enterprise investment in R&D.Additionally,despite being subject to certain conditions,the water resource tax still plays the leverage effect of green taxation,stimulating investment in technology R&D by high water-consuming enterprises.The research findings reveal the driving mechanisms and key factors of water resource tax on the cooperative R&D of water-saving technology in high water-consuming enterprises,offering valuable insights for the sustainable development of high water-consuming enterprises under the background of water resource tax.
