Abstract:Comprehensively addressing “involutionary competition” has emerged as a critical practical challenge. However, existing studies largely remain at the level of holistic attribution or superficial classification of behavioral manifestations, lacking in-depth analysis of its differentiated formation pathways. This study employs the grounded theory approach, following theoretical sampling principles, and selects three representative industries which are new energy vehicle industry, biopharmaceutical industry and steel industry for cross-case comparative analysis, aiming to deeply revel the formation mechanisms of “involutionary competition”. The findings indicate: (1) Three types of manufacturing “involutionary competition” based on different core drivers are identified: policy-induced, technology lock-in, and stock stalemate types. These three involution types are respectively dominated by distorted industrial policy incentives, systemic innovation capacity constraints and structural rigidity on both the supply and demand sides, exhibiting significant differences in core contradictions, competitive interaction patterns, and evolutionary pathways. (2) The formation mechanisms of manufacturing “involutionary competition” also exhibit differentiated characteristics depending on the type: Policy-induced involution follows the logic of "incentive distortion—competition response" , manifested as enterprises pursuing policy dividends and falling into homogeneous expansion and price wars; Technology lock-in involution follows the logic of "capability constraint—imitation lock-in", reflected in firms clustering in low-risk tracks due to insufficient innovation capacity; Stock stalemate involution follows the logic of "structural rigidity—survival game", presenting as enterprises trapped in the dilemma of price cuts to maintain sales volume under the dual pressures of high exit barriers and shrinking demand. (3) Although the formation mechanisms differ across types of involutionary competition, their evolutionary processes follow a certain common logic. This process begins with the combined effect of incentive distortions and capacity or resource constraints, triggering the alienation of firms" competitive behaviors, specifically manifested as price wars, resource misallocation and innovation deviation; Subsequently, under the effect of a self-reinforcing negative cycle, the industry is ultimately locked into a low-level equilibrium. By identifying the types of involution-style competition and constructing a mechanism model, this study provides a research foundation for accurately identifying and categorically governing involutionary competition and deepening relevant theories, while also offering decision-making references for enterprises to avoid competitive traps and promote sustainable industrial upgrading.
