بررسي رقابت ميان زنجيره هاي تأمين خودروهاي برقي، فسيلي و با سوخت تركيبي با در نظر گرفتن سيست هاي حمايتي دولت با استفاده از رويكرد نظريه بازي

Abstract In recent years, increasing environmental pressures, the growing deman‎d for clean vehicles, an‎d the strategic orientation of governments toward sustainable development have presented the automotive industry with novel challenges an‎d opportunities. In this context, the competitive lan‎dscape among fossil-fuel, electric, an‎d hybrid vehicle supply chains—particularly within the framework of government supportive policies—has emerged as a critical an‎d multidimensional issue. Furthermore, the simultaneous decisions of key players in these chains, including the government, the vehicle manufacturer, an‎d two energy suppliers, have a direct impact on economic, environmental, an‎d social efficiency. This research utilizes a game-theoretic approach to develop a competitive model among the supply chains of three vehicle types. The decision-making structure of the chain incorporates a vehicle manufacturer, two energy suppliers (electricity an‎d fossil fuels), an‎d end-consumers, while government supportive policies are integrated as a regulator an‎d policymaker. These policies include direct production subsidies, tax credits, technology investment grants, an‎d consumer purchase incentives. By designing an‎d analyzing several policy scenarios, this study examines the impact of each policy on variables such as deman‎d, price levels, supply chain membersʹ profits, an‎d government utility (Social Welfare). Numerical analysis conducted using simulated data indicates that the implementation of intelligent government policies can not only shift the competitive balance toward clean vehicles but also lead to simultaneous improvements in economic an‎d environmental indicators. This research fills the existing gap in the literature regarding supply chain competition with a dual-supplier structure an‎d multi-vehicle manufacturing, providing a decision-oriented an‎d analytical framework for optimizing government policies. The findings an‎d results of this study can effectively inform the decision-making of policymakers, manufacturers, an‎d energy suppliers to achieve sustainable development goals an‎d social welfare.
