Abstract

This study aims to investigate the spatiotemporal evolution of China's agricultural carbon emissions intensity and their influencing factors from 2001 to 2022. It employs analytical methods such as kernel density estimation, Gini coefficient, Moran's index, spatial Markov analysis, and spatiotemporal geographically weighted regression (GWTR) to visualize the data and analyze the results. The study ultimately draws the following. Conclusions (1) China's agricultural carbon emissions intensity shows a decreasing trend, a noticeable decrease in the number of provinces below the medium level. Gini coefficient analysis indicates a significant disparity between eastern and western China, with agricultural carbon emissions intensity exhibiting the spatial pattern: east > central > west. (2) China's agricultural carbon emissions intensity exhibits clear spatial clustering characteristics and a stable transfer trend. High-high agglomeration areas are primarily located in the Northwest and Northeast, while low-low agglomeration areas are mainly found in Guangdong and Fujian provinces. Furthermore, the transfer of agricultural carbon emission levels is stable. (3) Financial support and the development level of technology markets positively impact China's agricultural carbon emissions, while research and development intensity, openness to the outside world, human capital level, and urbanization negatively affect these emissions.

摘要

本研究旨在探讨2001年至2022年中国农业碳排放强度的时空演变及其影响因素。它采用核密度估计、基尼系数、莫兰指数、空间马尔可夫分析和时空地理加权回归(GWTR)等分析方法对数据进行可视化并分析结果。该研究最终得出以下结论:(1)中国农业碳排放强度呈下降趋势,中等水平以下省份数量明显减少。基尼系数分析表明中国东西部之间存在显著差异,农业碳排放强度呈现出东部>中部>西部的空间格局。(2)中国农业碳排放强度呈现出明显的空间集聚特征和稳定的转移趋势。高高集聚区域主要位于西北和东北地区,而低低集聚区域主要分布在广东和福建等省份。此外,农业碳排放水平的转移是稳定的。(3)财政支持和技术市场发展水平对中国农业碳排放有正向影响,而研发强度、对外开放程度、人力资本水平和城市化对这些排放有负向影响。
