Abstract The competitiveness of reverse-innovated products by emerging market firms in overseas markets is constrained by the scarcity of high-value patents.Adopting an ecological perspective,this study proposes a theoretical framework to analyze the value relationships and evolutionary pathways of high-value patents across three dimensions including technology,law and market.A three-dimensional Lotka-Volterra model is developed to explore the evolution of patent value and its optimal formation conditions in reverse innovation.Using BYD as a case study,the findings reveal that technological,legal,and market values jointly influence high-value patent evolution.Firms can develop high-value patents during reverse innovation,particularly in overseas markets.Moreover,the evolutionary path adapts to market changes,ultimately reaching an optimal high-value patent state through a prolonged evolutionary cycle.
