摘要:

【目的】 科学揭示新旧动能转换背景下耕地低碳利用效率时空演变特征,深入辨析耕地低碳利用效率提升的差异化组态路径,以期为耕地高效可持续利用、农业新质生产力培育乃至农业高质量发展提供决策依据。【方法】 在界定新旧动能转换背景下耕地低碳利用效率内涵及构建其组态路径理论框架基础上,基于广东省2010—2021年间21个地级市的面板数据,采用非期望产出的Super-SBM模型评估新旧动能转换背景下的耕地低碳利用效率并刻画时空演化特征,运用模糊集定性分析法(fsQCA)探讨耕地低碳利用效率提升的差异化组态路径。【结果】 (1)从时序特征看,2010—2021年广东省耕地低碳利用效率呈现在波动中缓慢上升的特征,均值为0.947;珠三角和粤北地区的演变特征与省级层面类似,粤东波动较小,粤西则呈现在波动中下降的态势,只有珠三角效率均值大于1;从空间分布看,广东省耕地低碳利用效率空间分异特征显著,呈高、低效率区多核心成片分布,尤以珠三角高效率及粤北低效率现象突出。(2)广东省耕地低碳利用效率提升路径可归纳为社会经济或政府支持单因素、技术赋能-政府支持或社会经济-政府支持双因素、资源禀赋-社会经济-政府支持多因素主导三类组态路径。(3)社会经济发展水平和政府支持程度是影响耕地低碳利用效率的最具普遍性因素,而耕地资源禀赋条件和农业技术投入水平的影响相对较弱。这些因素在特定的条件下能发生等效替代,耕地资源禀赋能够被其他三类因素单独或形成的组合所取代,构成提升耕地低碳利用效率“殊途同归”的路径。【结论】 耕地低碳利用是一个受“资源-经济-技术-政策”复杂系统因素交互影响的组态问题,实际中应注重其提升路径设计的整体谋划和因地施策。当前耕地数量受到严重威胁,持续在社会经济发展、财政支农力度以及农业生产技术水平等方面发力应成为促进耕地低碳高效利用长期坚持的方向。

Abstract:

【Objective】 To scientifically reveal the spatio-temporal evolution characteristics of the low-carbon use efficiency of cultivated land under the background of new and old kinetic energy conversion, and deeply analyze the differentiated configuration paths for improving the low-carbon use efficiency of cultivated land, so as to provide decision-making basis for the efficient and sustainable use of cultivated land, the cultivation of new agricultural productive forces, and even the high-quality development of agriculture.【Method】 Based on defining the connotation of the low-carbon use efficiency of cultivated land under the background of new and old kinetic energy conversion and constructing a theoretical framework for its configuration path, using the panel data of 21 prefecture-level cities in Guangdong Province from 2010 to 2021, the Super-SBM model with undesired outputs was adopted to evaluate the low-carbon use efficiency of cultivated land under the background of new and old kinetic energy conversion and depict the spatio-temporal evolution characteristics, and the fuzzy-set qualitative comparative analysis (fsQCA) was used to explore the differentiated configuration paths for improving the low-carbon use efficiency of cultivated land. 【Result】 (1) From the perspective of temporal characteristics, the low-carbon use efficiency of cultivated land in Guangdong Province showed a slow upward trend with fluctuations from 2010 to 2021, with an average value of 0.947; the evolution characteristics of the Pearl River Delta and Northern Guangdong were similar to those at the provincial level, Eastern Guangdong had small fluctuations, while Western Guangdong showed a downward trend with fluctuations, and only the Pearl River Delta had an average efficiency value greater than 1; from the perspective of spatial distribution, the spatial differentiation characteristics of the low-carbon use efficiency of cultivated land in Guangdong Province were significant, showing a multi-core and contiguous distribution of high and low efficiency areas, especially the prominent phenomena of high efficiency in the Pearl River Delta and low efficiency in Northern Guangdong. (2) The paths for improving the low-carbon use efficiency of cultivated land in Guangdong Province could be summarized into three types of configuration paths: single-factor dominated by socio-economic or government support, two-factor dominated by technological empowerment-government support or socio-economic-government support, and multi-factor dominated by resource endowment-socio-economic-government support. (3) The level of socio-economic development and the degree of government support were the most universal factors affecting the low-carbon use efficiency of cultivated land, while the influence of cultivated land resource endowment conditions and the level of agricultural technology investment was relatively weak. These factors could undergo equivalent substitution under specific conditions, and cultivated land resource endowment could be replaced by other three types of factors alone or in combination, forming the "same goal through different paths" for improving the low-carbon use efficiency of cultivated land.【Conclusion】 The low-carbon use of cultivated land is a configuration problem affected by the interaction of factors in the "resource-economy-technology-policy" complex system. In practice, attention should be paid to the overall planning of the design of improvement paths and policy implementation according to local conditions. At present, the quantity of cultivated land is under serious threat, and continuous efforts in socio-economic development, financial support for agriculture, and the level of agricultural production technology should become the long-term direction for promoting the low-carbon and efficient use of cultivated land.
