Fiscal decentralization and the transformation of regional energy structures in China: Spatial spillover effects and the mediating role of technological innovation
Abstract
The transformation of regional energy structures plays a pivotal role in enhancing ecological quality and advancing national green development efficiency. However, this transformation is characterized by dual externalities, necessitating governmental intervention to rectify market failures. Therefore, this study focuses on the critical influence and mechanisms through which local governments affect regional energy structure transformation, particularly within the context of China's unique fiscal decentralization. This study explores the impact of fiscal decentralization on the transformation of China's regional energy structures and its spatial correlations. Employing a bidirectional fixed-effect model and a spatial Durbin model, we analyze Chinese provincial panel data from 2002 to 2021 to explore the effects of fiscal decentralization on regional energy structure transformation and its spatial spillover. Findings reveal that fiscal decentralization significantly enhances the efficiency of regional energy structure transformation, with an effect coefficient of 0.127. Additionally, the fiscal decentralization mechanism positively influences spatial spillover effects on regional energy transformation, with these effects becoming more pronounced alongside higher degrees of economic agglomeration. Moreover, local governments are found to foster regional scientific and technological innovation, thereby facilitating adjustments in the regional industrial structure and promoting energy structure transformation. The intermediary effect test highlights the role of local governments in promoting scientific and technological advancements that drive industrial restructuring and energy transformation. The study recommends for a long-term strategy to balance central and local financial development, aiming to enhance the efficiency of regional energy structure transformation. These findings offer a theoretical foundation and policy recommendations for optimizing and transforming energy structures in pursuit of China's green and high-quality development goals. These findings offer globally relevant insights into leveraging fiscal decentralization for energy structure transformation, supporting sustainable development and green growth worldwide.
