Core Viewpoint - The article emphasizes the importance of the deposit insurance system as a crucial component of financial security in China, highlighting its role in maintaining financial stability and protecting depositors' interests, particularly in the context of its ten-year implementation since 2015 [1][4]. Summary by Sections Deposit Insurance Pricing Mechanism - The book systematically studies the deposit insurance pricing issue from three dimensions: regulatory penalties, interval pricing, and macroeconomic policy considerations. It introduces a tolerance coefficient into Merton's classic model, showing that increased regulatory penalties lead to lower risk preferences among banks and subsequently lower deposit insurance rates [1][2]. - The research also incorporates fuzzy mathematics into the deposit insurance pricing model, demonstrating the theoretical significance and practical necessity of interval pricing, ultimately deriving deposit insurance prices based on triangular intuition fuzzy numbers [1][2]. - The impact of tax reduction policies on the real economy and financial sector is analyzed, revealing that a decrease in income tax rates leads to lower deposit insurance premiums, with empirical evidence indicating that higher bank income tax rates increase risk-taking and thus raise deposit insurance rates [1][2]. Risk Effects of Deposit Insurance System - The study investigates the impact of the deposit insurance system on banks' risk-taking behavior through four dimensions: the influence mechanism, differentiated rates, early corrective actions, and prudent regulatory policies. It finds that the implementation of the deposit insurance system effectively reduces risk-taking levels among small and medium-sized banks [2][3]. - The research expands on classic theoretical models, proving that differentiated deposit insurance rates have a suppressive effect on banks' risk-taking, particularly in the context of rural commercial banks' reforms [2][3]. - The book constructs indicators to characterize the early corrective actions of the deposit insurance system, confirming its effectiveness in early risk correction through unique data on real deposit insurance rates for small and medium-sized banks [2][3]. Policy Recommendations for Improvement - The author proposes four policy recommendations to enhance China's deposit insurance system: accelerating the legislation of the Deposit Insurance Law to improve its role and independence; strengthening regulatory collaboration to enhance efficiency; establishing a financial firewall between small and large banks to reinforce oversight; and utilizing big data to improve risk management and public supervision mechanisms [3][4]. Overall Assessment - The book presents a comprehensive study of the deposit insurance pricing mechanism and the effects of the deposit insurance system, characterized by a framework that integrates empirical facts, pricing mechanisms, risk effects, and mechanism design. It effectively combines theoretical and empirical research, addressing both pricing mechanisms and risk effects in detail [4][5]. - The theoretical contributions include integrating prudent regulation and macroeconomic policies into deposit insurance pricing models, enriching the theoretical landscape of deposit insurance [4][5]. - The empirical focus on small and medium-sized banks provides valuable insights into the effects of the deposit insurance system, offering a scientific evaluation that can inform future improvements [4][5].
