The Impact of Market Integration Construction on the Innovation of Key Core Technologies of Enterprises: From the Perspective of Complex Adaptive System Theory

Achieving breakthroughs in key core technologies is an inherent requirement for attaining a high level of scientific and technological self-reliance. The construction of a unified market (market integration construction) reshapes the rules of the innovation system and drives enterprises to tackle key core technologies. Based on the theory of complex adaptive systems, this paper uses the data of China’s A-share listed companies from 2008 to 2023 and the statistical yearbook to study the impact of market integration construction on the key core technological innovation of enterprises and its mechanism. The empirical research results show that: (1) Market integration construction reconstructs the rules governing resource flow, competitive incentives, and collaborative networks, guiding enterprises to achieve the emergence of key core technologies through nonlinear interactions. (2) Market integration construction exerts distinct effects on key core technological innovation by enhancing industrial investment and financial investment. (3) Agile responsiveness positively moderates the relationship between market integration construction and key core technological innovation. (4) The positive impact of market integration construction on key core technological innovation is more pronounced in non-state-owned, follower, and large enterprises. This study provides a theoretical basis and practical insights for advancing market integration construction and tackling key core technologies.
