A Study of the Spatial Effects of Financial Support and Economic Growth under Optimal Control of Nonlinear Generalized Complex Systems

This paper provides an in-depth analysis and study of the spatial effects of financial support and economic growth with the help of nonlinear generalized complex systems. Taking the industrial sector as the research object and combining the relevant contents of neoclassical investment theory, information economics, and institutional economics, this paper clearly defines and argues that the main feature of current financial policy is financial constraint rather than financial inhibition based on an in-depth understanding of the theoretical connotation and policy rationality of financial constraint and, as a premise, further analyzes the financial constraint policy causing excessive investment and capital mismatch in the corporate sector. It further analyzes the mechanism of the role of financial constraint policies in causing overinvestment and capital mismatch in the corporate sector and conducts empirical tests from three research perspectives of measuring investment efficiency, output efficiency of investment, allocation efficiency of industry capital, and investment behavior of microenterprises, and finally puts forward relevant policy recommendations in conjunction with the evaluation of the efficiency of financial constraint policies. This paper selects three dimensions of the financial system, namely, financial structure, financial efficiency, and financial scale, and studies the adaptability between these three dimensions and the development of the real economy, respectively, and then uses different empirical methods to analyze the dynamic adaptability effects between the development of the real economy and these three dimensions of the financial system and finally explores the way of adaptability between the financial system and the development of the real economy. This paper provides a medium and micro theoretical basis and new empirical evidence for understanding the importance of financial system reform on economic growth and also opens up a space for exploring the exit path of financial constraints and using interest rate marketization as a general grip to reasonably guide financial resources to achieve economic transformation and upgrading and sustainable and healthy development through supporting high-quality investment, using more interprovincial level data in the analysis, so it is more comprehensive and detailed than previous scholars’ studies. The examination is more comprehensive and detailed than previous scholars’ studies.
