英文摘要
Reducing energy poverty has been recognized as an effective way to eliminate overall poverty and achieve sustainable development for individuals, which are two major global challenges. This study investigated how migration affected household energy poverty in rural China. Drawing on data from the China Family Panel Studies, we adopted the instrumental variable method to examine the causal relationship between internal migration and energy poverty and probe its mechanisms. We found that internal migration significantly reduced the likelihood of family energy poverty. Specifically, the probability of energy poverty in a family with labor migration was 13.1% lower than in a family without labor migration, and the probability of energy poverty decreased by 6.4% when each additional laborer in the family migrated. Furthermore, a heterogeneity analysis revealed that labor migration had a particularly significant impact on families in central and western regions and villages near counties. Migration also plays a more important role for low-income households with less educated male heads. The mechanism analysis revealed that labor migration could reduce the probability of family energy poverty by increasing family income, which outweighed the negative effects of the increased share of elderly and children left behind by migration. These findings offer important policy insights for countries undergoing development and transformation.
文章概要
减轻相对能源贫困被认为是消除整体贫困和实现个人可持续发展全球两大挑战的有效途径。本文研究了劳动力流动对于中国农村家庭相对能源贫困的影响。本文运用工具变量法，基于中国家庭追踪调查（CFPS）数据，实证研究了劳动力流动对于家庭相对能源贫困的影响及其机理，并对跨区域流动和本地就业非农的效用做了区分。通过研究发现，劳动力流动可以显著降低家庭的相对能源贫困，相比于没有劳动力流动的家庭，有劳动力流动的家庭相对能源贫困程度降低13.1%；每当家庭有一个劳动力外出时，家庭相对能源贫困程度降低6.4%。进一步地，通过异质性分析发现，劳动力流动在中西部地区和距离县城较近的农村对于减轻家庭相对能源贫困程度的效果更明显；在户主为男性的低收入家庭中这一效用也更为显著。机制分析表明，劳动力流动主要通过增加家庭收入、改变家庭留守人口结构来减轻家庭的相对能源贫困程度。本文的研究结论对其他发展中国家以及面临能源结构转型的国家具有重要的政策启示。
该研究成果曾在The Sustainability and Development Conference（2022）以及第一届“发展·共享”论坛等学术会议上进行交流，收获同行专家评审意见，并荣获第二届全国大学生发展经济学大赛三等奖。
