Abstract

One of the secrets for China's economic growth miracle is continuous investment in infrastructure, and the role of power infrastructure is irreplaceable. However, previous studies mostly focused on generation-side indicators rather than grid-side indicators, ignoring the importance of the mega-grid established in China. As a result, this paper is committed to exploring the economic growth pulling effect of power grids with different voltage levels in the nonlinear framework. On the premise of determining the robustness of estimation parameters by instrumental variable method, the panel smooth transition regression (PSTR) model is used to capture panel heterogeneity. To be exact, the regional economic growth driven by extra-high voltage (EHV) and ultra-high voltage (UHV) power grids presents a regime transition accompanied by the growth of regional power generation and electricity consumption per capita. This means that the mega-grid is more conducive to the economic growth of energy bases and load centers. To further build and improve the state-leveled mega-grid into a nationwide basic platform for trans-regional renewable energy transmission and distribution is a key measure to enhance China's sustainable economic growth under the constraints of carbon peak and carbon neutrality targets.

巨型电网对区域经济增长的推动作用:基于面板平滑过渡回归模型的中国证据

中国经济增长奇迹的秘诀之一，就是对基础设施的持续投入，而电力基础设施的作用是不可替代的。然而，以往的研究大多侧重于发电侧指标，而不是电网侧指标，忽视了中国建立特大电网的重要性。因此，本文致力于探讨在非线性框架下不同电压水平电网的经济增长拉动效应。在工具变量法确定估计参数稳健性的前提下，采用面板平滑过渡回归(PSTR)模型捕捉面板异质性。确切地说，特高压和特高压电网带动的区域经济增长，伴随着区域发电量和人均用电量的增长，呈现出一种制度变迁。这意味着大电网更有利于能源基地和负荷中心的经济增长。在碳峰值和碳中和目标约束下，进一步建设和完善国家级大电网，使其成为全国性的跨区域可再生能源输配基础平台，是促进中国经济可持续增长的关键举措。

期刊介绍： Energy & Environment is an interdisciplinary journal inviting energy policy analysts, natural scientists and engineers, as well as lawyers and economists to contribute to mutual understanding and learning, believing that better communication between experts will enhance the quality of policy, advance social well-being and help to reduce conflict. The journal encourages dialogue between the social sciences as energy demand and supply are observed and analysed with reference to politics of policy-making and implementation. The rapidly evolving social and environmental impacts of energy supply, transport, production and use at all levels require contribution from many disciplines if policy is to be effective. In particular E & E invite contributions from the study of policy delivery, ultimately more important than policy formation. The geopolitics of energy are also important, as are the impacts of environmental regulations and advancing technologies on national and local politics, and even global energy politics. Energy & Environment is a forum for constructive, professional information sharing, as well as debate across disciplines and professions, including the financial sector. Mathematical articles are outside the scope of Energy & Environment. The broader policy implications of submitted research should be addressed and environmental implications, not just emission quantities, be discussed with reference to scientific assumptions. This applies especially to technical papers based on arguments suggested by other disciplines, funding bodies or directly by policy-makers.
