Research on the Mechanism and Enhancement Path of the Domestic Economic Circulation's Impact on the Controllability of High-Tech Industrial Chains

Abstract

Against the backdrop of global industrial chain restructuring and intensified technological blockade, enhancing the controllability of key links in high-tech industrial chains has become a crucial strategic task in building my country's new development pattern. The domestic economic cycle, as a core support for the smooth operation of the national economic system in the new development stage, may become a significant mechanism driving the self-reliance and resilience of industrial chains through its structural functions in promoting factor flows, strengthening industrial support, and expanding domestic demand. However, existing research lacks a systematic theoretical framework and mechanism identification for "how the domestic economic cycle affects the controllability of high-tech industrial chains." Based on this, this paper constructs a domestic economic cycle index from the three-dimensional structure of supply, demand, and circulation, and designs an evaluation system for the controllability of industrial chains around the controllability of independent technologies, the localization rate of key links, and the risk of external dependence. On this basis, it constructs a framework of the mechanism of "domestic economic cycle → resource allocation efficiency → self-reliance enhancement," analyzing the inherent logic of the cycle-driven formation of controllability. The study further points out that policy tools such as fiscal subsidies, government procurement, and guidance funds have significant reinforcing or mediating effects in the mechanism chain, and can further enhance controllability by improving innovation capabilities, improving industrial synergy, and reducing external dependence. Finally, based on the mechanism identification results, this paper proposes three paths to enhance the controllability of high-tech industrial chains: localization of supply-side development, coupling of innovation chains and industrial chains, and optimization of policy support systems. This research provides a new analytical framework for understanding the structural role of the domestic economic cycle in industrial chain security, and also offers policy references for the government to promote the independent control and security governance of high-tech industrial chains in the new era.
