“…In the past, the literature mostly used static and regression methods to analyze influencing factors, ignoring the optimal allocation efficiency of central subsidies (the local government maximizes self‐raised financial resources and central financial resources under the optimal scale of current expenditure and capital expenditure to achieve the goal of minimizing debt). Some scholars study the relationship between government debt and national economic growth, such as Chorafas (2014), Casalin et al (2019), Croce et al (2019), Bal and Rath (2014), Nakamura (2017), Rathnayake (2020), Afonso and Jalles (2020), Chen and Wu (2018), De Jong and Gilbert (2020), and Qureshi and Liaqat (2020). Studies have pointed out the impact of fiscal decentralization on regional health policies (Di Novi et al, 2019), and some scholars have explored the benefits of government tax collection on fiscal decentralization to local governments and residents' poverty (Bellofatto & Besfamille, 2018; Sanogo, 2019), but these studies still focus on the static and causal relationship.…”
