Abstract

In the context of tightening resource and environmental constraints, quantitative measurement and influencing factors of cultivated land use eco-efficiency (CLUE) have become hot topics in current academic research. Existing studies primarily focus on the influence of natural, social, and economic factors on CLUE but ignore exploring the impact mechanism and effect of environmental policies on CLUE. Therefore, this study aims to explore the impact of environmental regulations on CLUE. To achieve this objective, a super-efficiency slack-based measure (super-SBM) model is used to calculate the CLUE for 31 provinces (municipalities and autonomous regions) in China from 2000 to 2009. Additionally, the intermediary effect model and the threshold effect model are used to empirically investigate the transmission mechanism and nonlinear characteristics between environmental regulation and the CLUE. The results show that: (1) the temporal dynamics of CLUE exhibit a pattern of initial fluctuating decline followed by gradual growth in China as a whole and across its eastern, central, and western regions. (2) Environmental regulation has a significant negative impact on CLUE, and the effect exhibits a nonlinear characteristic of decreasing marginal effects. (3) Agricultural technological innovation and agricultural industrial structure play a mediating role between environmental regulation and CLUE, reducing the negative impact of environmental regulation on CLUE. This study provides some implications for formulating scientifically sound environmental policies to optimize land use and enhance resource utilization efficiency.

环境规制对耕地生态效率的影响:来自中国的证据

在资源环境约束趋紧的背景下，耕地利用生态效率的定量测度及其影响因素已成为当前学术界研究的热点。现有研究主要关注自然、社会和经济因素对CLUE的影响，忽视了环境政策对CLUE的影响机制和效果。因此，本研究旨在探讨环境法规对CLUE的影响。为了实现这一目标，采用超效率的基于松弛测度(super-SBM)模型对中国31个省(市、自治区)2000 - 2009年的CLUE进行了计算。此外，利用中介效应模型和阈值效应模型实证研究了环境规制与CLUE之间的传导机制和非线性特征。结果表明:(1)中国整体和东、中、西部地区CLUE的时间动态表现为先波动下降后逐渐增长的格局。(2)环境规制对CLUE具有显著的负向影响，且边际效应呈现递减的非线性特征。(3)农业技术创新和农业产业结构在环境规制与CLUE之间起中介作用，降低了环境规制对CLUE的负面影响。本研究为制定科学合理的环境政策以优化土地利用，提高资源利用效率提供了参考。

期刊介绍： Agriculture (ISSN 2077-0472) is an international and cross-disciplinary scholarly and scientific open access journal on the science of cultivating the soil, growing, harvesting crops, and raising livestock. We will aim to look at production, processing, marketing and use of foods, fibers, plants and animals. The journal Agriculturewill publish reviews, regular research papers, communications and short notes, and there is no restriction on the length of the papers. Our aim is to encourage scientists to publish their experimental and theoretical research in as much detail as possible. Full experimental and/or methodical details must be provided for research articles.
