Abstract: This paper examines the historical evolution，institutional characteristics，and academic debates surrounding the tax-sharing system reform，aiming to clarify the reforms institutional effects on local government debt governance and to outline potential pathways for further reform Amidst the pursuit of highquality development，it is imperative to advance local government debt governance It not only concerns the strategic outlook of preventing and resolving major economic and financial risks，it also underscores its theoretical value There are practical significances in nurturing financial resources and fostering new development impetus Furthermore，it plays a significant role in constructing a highlevel socialist market economy system
It posits that the tax-sharing system reform effectively leverages the “dual incentives” of central and local governments，thereby laying the groundwork for a decentralized governance framework aligned with the socialist market economy From an institutional economics perspective，the reform of the taxsharing system primarily influences the policy direction of local government debt governance through fiscal and political incentives This paper aims to address three key academic debates Firstly，it argues that the financing patterns of local government debt prior to the taxsharing system reform do not diminish the institutional impacts brought about by the reform Secondly，it suggests that vertical transfer payments not only fail to mitigate the fiscal incentives of the taxsharing system reform but also exacerbate the “common pool” effect on local government debt governance Thirdly，following the implementation of the taxsharing system reform，there has been a notable shift in the motivational dynamics driving local officials towards debt financing，transitioning from “a profitdriven orientation” to “one predominantly focused on risk mitigation and avoidance strategies” Furthermore，this paper analyzes the implications of the taxsharing system reform，finding that it effectively harnesses the “dual incentives” of central and local governments，thereby encouraging local governments to issue debt for the construction of municipal infrastructure By integrating administrative mobilization capabilities with market enhancement abilities，the reform has spurred considerable infrastructure development at the local level However，the focus on “respond to superiors” rather than “respond to subordinates” in the responsibility constraint mechanism has also led to the continuous generation，expansion，and concealed accumulation of local government debt risks 
This paper provides strategic reform directions for fiscal power division，authority allocation，administrative supervision，and market constraints to promote the taxsharing reform and local government debt governance under the context of highquality development，with the aim of building a highlevel socialist market economy system
