High Temperature, Multidimensional Poverty, Rural Revitalization, Counties in Northern Jiangsu.Abstract
Against the backdrop of intensifying global climate change and the in-depth implementation of the rural revitalization strategy, the contradiction between climate shocks and sustainable rural development has grown increasingly prominent. Taking counties in northern Jiangsu as the research sample and utilizing panel data from 2000 to 2023, this paper first constructs a county-level multidimensional poverty index (MPI) encompassing economic development, educational resources, and medical resources via the entropy method. From the three dimensions of agricultural production, labor supply, and living costs, it then empirically examines the transmission mechanisms through which high temperature affects county-level multidimensional poverty, using a two-way fixed effects model and a mediation effect model. The results indicate that high-temperature weather significantly aggravates multidimensional poverty in counties of northern Jiangsu. The impact is transmitted through three main channels: the core pathway is the suppression of agricultural output; additionally, high temperature reduces the effective labor supply in agriculture, forestry, animal husbandry and fishery, and drives up residential electricity costs for urban and rural residents, jointly amplifying the poverty effect. Accordingly, this paper proposes targeted strategies including industrial structure optimization, rural financial innovation, and infrastructure upgrading, providing practical references for northern Jiangsu to address climate risks and achieve sustainable rural revitalization.
