Research on the Spatio-Temporal Evolution and Differentiated Improvement Path of Low-Carbon Utilization Efficiency of Cultivated Land Under the Background of New and Old Kinetic Energy Conversion——A Case Study of Guangdong Province
摘要
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.关键词
