The No.1 Central document for 2026 emphasizes enhancing soybean production capacity, expanding the cultivation space for rapeseed, peanuts, Camellia oleifera, and other oil crops, and increasing the diversified supply of oilseeds. On this basis, how to further enhance the competitiveness of Guangdong's oilseed industry and achieve its high-quality development is of great significance for ensuring the supply of oil crops and the production of edible oil in China. This study analyzes the current situation of oil crop production, cost-benefit, mechanization and processing levels, and policy support in Guangdong Province. The results indicate that: (1) As a major producer of oil crops in China, Guangdong Province has maintained the third-largest peanut sown area in the country for years. Peanuts accounted for 50% of the increase in total sown area of oil crops in Guangdong Province, with western and northern regions contributing 70% of the province's total peanut production. (2) Oil crop production in Guangdong still requires substantial improvement, as peanut yields per mu and net profits remain relatively low, while production costs have risen excessively. Moreover, compared with Henan and Shandong Provinces, Guangdong exhibits a markedly lower level of comprehensive mechanization in oil crop cultivation. (3) Guangdong is a leading province in peanut and soybean breeding, and has been actively promoting "green, high-yield, and efficient" cropping systems. It ranks first nationwide in the number of edible oil processing enterprises and has been implementing multi-tier agricultural insurance schemes for oil crops. On this basis, the challenges faced by the oil industry in Guangdong Province were discussed as follows: Limited space promotion, slow selection and breeding of improved varieties, difficulty in promoting new varieties; The planting benefit is low, and the cost of labor and agricultural materials rises; Policy support system and farmers' awareness of policy need to be improved; Low degree of organization, insufficient extension of industrial chain; The construction of policy support system for oil crops needs to be improved. Accordingly, relevant policy suggestions were put forward for the development of oil industry in Guangdong Province: Strengthen the support of oil crop science and technology and equipment; Innovate the organizational forms and value chain extension of the oilseed industry; Enrich the financial and financial policy support system of the oil industry; Promote industrial spatial agglomeration and chain collaboration, and build modern oilseed industrial clusters.

Land distribution is intricately linked to economic quality and sustainable growth, influenced by administrative division adjustment (ADA), which can be categorized into various forms, with the township-town merge (TTM) reform being the most common. This study evaluates the effect of TTM on local governments' dependence on polluting industries from a fiscal decentralization angle, using the differences-in-differences model with transaction data from China's land market. Findings reveal that TTM increases local governments' dependence on polluting industries, especially in districts/counties with weaker economic conditions before the COVID-19 pandemic. Evidence also highlights a notable boundary effect of TTM, though its impact is minimal in districts/counties at provincial borders due to their potentially lower public investment inclination. TTM also increases the decentralization level of districts/counties, thus explaining the increase in local government's dependence on polluting industries. The empirical results have confirmed such a mechanism. However, top-down supervision limits the effect of the reform to a certain extent. This conclusion offers fresh policy insights for leveraging land supply mechanisms to advance environmental governance in centralized developing nations through the lens of ADA.

China aims to reduce carbon emissions but faces challenges from small-scale farmer operations. Previous studies have predominantly examined carbon density using macro-level data. This study employs a primary field survey involving 916 rice farmers, along with input–output data from their typical paddy plots, to calculate micro-level carbon emissions and assess the impact of land operation scale. The results indicate that operational scale enhances carbon emission productivity and has a nonlinear relationship with carbon emission intensity. From survey data, the carbon emission intensity of late rice is 4648.77 kg CO2eq·ha−1 in Guangdong province China, which differs by a mere 1.14% from the figure derived from yearbook macro data. The yield carbon emission productivity and yield value carbon emission productivity of rice production are 1.347 kg·kg CO2eq−1 and 2.166 CNY·kg CO2eq−1, respectively. The operational scale significantly positively enhances indirect carbon emission productivity, a key indicator of economic growth and environmental sustainability. However, it exhibits a U-shaped effect on carbon emission intensity. Our results underscore the critical role of expanding the operational scale among individual farmers to boost carbon emission productivity, facilitating the simultaneous development of grain crops and a reduction in carbon emissions.

Urban land marketization is a strategy to alleviate land resource misallocation caused by government intervention, but there has been a debate regarding its effectiveness in reducing carbon emissions. This study examines the impact of market-oriented allocation of land resources on carbon emissions using panel data from 284 Chinese cities from 2007 to 2021. The results indicate four findings: (1) Urban land marketization can effectively reduce both the total carbon emission and carbon emission intensity, especially in the central and western cities, non-provincial capital cities, and resource-dependent cities. (2) Promoting land financing, expanding trade openness, and stimulating entrepreneurship are all significant mechanisms for the carbon emission reduction effect of urban land marketization. (3) As per capita income and environmental regulation increase, the impacts of land marketization on carbon emissions are nonlinear. (4) Surrounding cities’ carbon emissions are not mitigated due to administrative border barriers and regional protectionism. This paper sheds light on the role of land marketization in carbon emission reduction and thus provides practical policy implications for promoting economic transition and low-carbon development.

The rent-free farmland transfer that exists widely in China’s rural areas is a topic worthy of attention. Particularly, the regional heterogeneity of its occurrences implies regional cultural heterogeneities. Using local dialects to proxy regional cultural features, this study applies econometric methods to examine the impacts of dialect diversity on rent-free farmland transfers. It also considers possible mechanisms through a mediation analysis, based on a combined two-year rural household survey dataset from the Guangdong and Jiangxi Provinces in 2015 and 2016. Robust estimation results reveal that dialect diversity increases the probability of rent-free farmland transfers at the household and village levels. According to the mediation analysis, dialect diversity influences villages’ farmland abandonment, rural farmland market development, and the flexibility of farmland transfer contracts, which further affects rent-free farmland transfer. Rent-free farmland transfer depends on social trust and contracts’ self-fulfilling advantages. Therefore, cultural and traditional factors should be taken into consideration, which would form beneficial interactions between the selections of rural farmland institutional arrangement and land rights policy implementations.

The capitalization of agricultural subsidies is highly relevant to sustainable agricultural development. This study applies meta-analysis to systematically investigate the overall mean effects of capitalization of agriculture subsidies in China, the EU, and the USA. We explore capitalization rates across different types and recipients, including potential sources of heterogeneity. Our primary objective is to address the debate of whether agricultural subsidies are ultimately capitalized into land rental prices. Results show that the overall mean effect of subsidies on land capitalization in the European Union (5.5%) is greater than that in the United States (2.9%), with no significant and positive effects observed in Chinese markets. Additionally, we conclude that decoupled payments may not reduce the capitalization of agricultural subsidies in the European Union and the USA. Notably, agricultural subsidies received by landowners/contractors tend to be lower than those received by tenants. Finally, the capitalization of agricultural subsidies is influenced by several potential sources of heterogeneity, including farmland scales, aggregated data, sample sizes, lagged subsidies, and the starting and ending dates of publications. These findings provide comprehensive insights into the capitalization of agricultural subsidies and offer practical policy recommendations for the effective mitigation of capitalization rates.

集体经营性建设用地入市改革是建立城乡统一的建设用地市场的重要举措.文章基于2008—2022年中共中央、国务院等相关部门发布的184份政策文件,在描述政策数量和结构等基本特征的基础上,结合政策试点三阶段理论将集体经营性建设用地入市政策演变过程划分为前试点(2008—2014年)、试点(2015—2019年)和试点后(2020—2022年)三个阶段,并使用ROST分析工具探讨政策的演变特征.结果发现,在改革的各阶段,中央的政策目标一致,但治理体系和协同项目根据实践暴露出的问题持续改进.据此,文章对集体经营性建设用地入市政策在土地增值收益分配制度、融资制度建立、交易平台建设以及改革协同等方面提出建议.

Digital transformation has become the most important path for enterprise transformation and upgrading. Existing research has deepened the society and entrepreneurs’ cognition of digital transformation. However, no scholars have paid attention to the relationship between enterprise digital transformation and investment efficiency, and few scholars have examined the economic effect of digital transformation from a non-linear perspective. Taking listed companies in China’s manufacturing industry since 2012, this paper analyzes the impact of different types of digital transformation on the investment efficiency of enterprises, and examines the intermediary effect of enterprise professional development and the adjustment effect of senior executives’ cognitive ability. The analysis found that digital transformation has a “inverted U”impact on the investment efficiency of enterprises. At the present stage, most enterprises have a low level of digital transformation, and the depth of digital transformation corresponding to the maximum investment efficiency has not yet been reached, indicating that the right negative effect of “inverted U” type mainly comes from a few extreme values. Professional development plays a significant intermediary role between digital transformation and investment efficiency. Digital transformation promotes the professional development of enterprises, and there is a “U-inverted” relationship between professional development and investment efficiency. The cognitive ability of senior executives has a regulatory effect on the relationship between digital transformation and investment efficiency, but it mainly occurs in the positive correlation stage of the two. The higher the cognitive ability of senior executives, the stronger the positive impact of digital transformation on investment efficiency. In addition, the heterogeneity analysis shows that the impact of the digital transformation on the investment efficiency only exists in the enterprises that actively implement the digital transformation, and the passive implementation of the digital transformation cannot improve the investment efficiency of the enterprises.

作为国家空间治理的重要手段,行政区划调整涉及地区资源和权力的再配置,对土地利用尤其是耕地征收有着重要影响.本文利用2003-2019年全国地级以上城市数据,构建准自然实验,分析撤县设区改革对耕地征收规模的影响发现:(1)撤县设区改革在短期内显著抑制了耕地征收规模且结果稳健,异质性检验表明其抑制作用在东部地区和粮食主产区更为明显.(2)围绕土地利用变化以及土地监管等方面的机制分析表明,撤县设区改革促进了建成区扩张,建成区扩张对改革效果具有遮掩效应;改革通过推高一级土地市场价格、增加城投债的发行规模、提高土地管制等途径抑制了耕地征收.本文重新审视了行政主导型城镇化模式的土地利用效应,有助于为强化耕地保护提供新的政策思路.

小农户退出农地经营,不仅涉及中国农业经营主体转换与基本经营制度变革的基础性问题,而且关联到国家农业安全特别是粮食安全等重大议题.农机服务市场发育对小农户农地经营是否存在着"挤出"效应,尚未得到一致结论.利用河南省小麦种植样本农户数据进行实证分析,结果表明:(1)外包服务促进了小农户退出农地经营,主要表现为促进农地转出而不是农地撂荒,且对均值规模以下的农户退出行为的影响更为明显.(2)异质性分析并未改变外包服务对农地经营影响的主效应,且要素市场发育亦有利于推动农地转出,并有效抑制农地撂荒.(3)进一步的分析表明,服务价格上涨推动了农户退出农地经营,但外包服务的本地化则减缓了农地经营的退出.文章认为,应该关注外包服务的"双刃剑"作用,加快相关要素市场的发育及其匹配,搭建农机服务信息平台,稳妥推进小农户农地经营退出的相关制度建设.

乡村生态振兴对于推进农民走向共同富裕至关重要,但作用机理并不清晰.文章构建"农民收入—要素配置—生态环境"的分析线索,使用中国劳动力动态调查数据(CLDS),揭示生态振兴赋能农民共富的实现路径.结果表明:(1)经济收入对农民幸福感产生"倒U型"影响.但在拐点来临之前,促进收入增长仍是提升幸福感并推进共同富裕的重要措施.(2)收入具有结构性差异.其中,由外出务工获得的非农收入隐含"人户分离"及情感缺失,对农民家庭幸福产生"倒U型"影响,农业收入则能够持续地增进幸福感.(3)农业具有生态依赖性.特别地,生态振兴通过促进农地经营规模、农业劳动力供给与农业长期投资进而实现农业增收.进一步的分析表明,生态环境显著地缩小了城乡收入差距并有助于实现全局意义上的共同富裕.文章认为,单纯以非农收入为导向不利于增进农户幸福感,有必要通过生态振兴促进农业经营性增收以诱导他们走向共同富裕.

一、问题的提出 农村劳动力非农转移是社会经济发展中的必然现象.在中国工业化城镇化的转型发展过程中,亿万劳动力从农村涌向城市成为一种重要的社会经济现象.数据显示,2010年之后中国的农民工数量持续稳定在2.5亿人以上,2020达到了 2.86亿人,大约占到了全国总人口的1/5.事实上,农村劳动力非农转移并非是要素市场发育的独立事件,而是与农业制度尤其是与地权制度变革紧密关联[45-46].自改革开放以来,中国政府在农村土地制度层面不断强化农地产权的稳定性.地权从模糊走向明晰、从调整走向稳定,农地产权从弱化走向强化成为新时期中国农村地权制度改革的基本特点,由此也诱发了农业劳动力市场的转变.正是由于农村地权稳定的政策努力及其动态变化,对农村劳动力非农转移的影响呈现出鲜明的阶段性特征.

农业“走出去”战略为我国种业发展提出了新的挑战和机遇.以袁隆平农业高科技股份有限公司作为研究对象,采用事件研究法和会计指标法分析我国种业上市公司海外投资行为对公司绩效的影响.对比隆平高科收购陶氏益农的三个阶段签署协议、宣布收购和完成收购的市场模型,发现只有在完成收购阶段才会对股价产生影响;短期来看,海外投资对企业短期绩效有正向影响,有利于隆平高科再融资;长期来看,海外投资并未明显改善公司绩效.建议:一是种业企业应立足战略型基础产业,制定企业海外投资的长期发展战略,保持海外投资战略定力;二是借助“一带一路”倡议实施契机,强化与沿线国家的合作,实现种业资源的优势互补;三是关注种业企业海外投资的后续发展问题.

文章以中国一拖集团为研究对象,以设立一拖科特迪瓦农机装备公司、收购McCormick法国工厂以及设立一拖白俄技术有限公司等为研究事件,旨在分析农业机械上市公司海外投资行为对公司绩效的影响.实证结果表明:(1)中国一拖海外投资对短期绩效的影响方向不明确;(2)海外投资对中国一拖长期绩效的影响仅表现为对H股的存货流动性和资产负债率的正向影响,需指出的是这些指标亦受制于农业机械工业行业总体发展.针对上述结论,文章提出如下政策建议:进一步完善和落实我国农业机械产品出口的优势政策体系;农业机械企业要做好海外投资的长期战略规划;要通过实施品牌战略,提高产品的附加值和市场竞争力;要实现国际营销和农业机械国外售后服务一体化.

我国农业已经进入高成本时代,其中农地租金的快速增长备受关注.采用2015年和2016年对广东与江西两省进行抽样问卷的4172个农户样本数据,考察不同类型农地市场结构和粮食直补政策对农户农地转出租金的影响发现:(1)农地租金上涨既是自发流转市场的必然结果,同时也是村集体主导或者村集体经济组织参与推动的结果;(2)当粮食直补分配给承租方时,不同类型的农地市场均会将粮食直补资本化为农地租金;(3)当粮食直补分配给承包者时,自发流转的农地市场会降低农地租金,而村集体主导的市场格局会推动农地租金上涨.因此,应妥善运用村集体和基层政府在农地流转中的“有形之手”,厘清政策目标间的冲突,适当调整农业补贴资本化为农地租金的政策倾向.

本文以2007年～2019年隆平高科、众兴菌业和海南橡胶的五起海外投资事件为研究对象,通过事件研究法、长期持有超额收益法分析海外投资对种植业企业短期和长期绩效的影响.结果表明:在短期,海外投资给种植业企业带来负向的绩效.而长期内海外投资行为未产生显著绩效.据此,本文提出做好市场预期引导、战略目标和绩效目标相结合、加大种业企业"走出去"实现种业资源优势互补的建议,以期为我国农业企业海外投资战略制定提供有益借鉴.

对于服务外包与化肥施用强度之间的关系,学术界虽积累了大量研究文献,但并没有得出一致的结论.文章运用荟萃分析方法,探究两者之间真实关系及其异质性来源.结果 表明:(1)服务外包与化肥施用强度之间具有微弱的负相关关系;(2)农户经营规模、受教育程度以及研究所在国别等因素作用于这种负向相关关系,并成为现有实证研究结论不一致的重要异质性来源.基于现有文献数据来看,尽管服务外包有助于化肥的减量化,但是不能忽视两者间的调节变量与隐性作用机制.

PurposeThe purpose of this paper is to assess the links between basic farmland preservation and land transfers in rural China.Design/methodology/approachThe Chinese provincial panel data from 2006 to 2016 were analyzed with the use of Arellano–Bond linear dynamic panel data estimations.FindingsThe basic farmland preservation policy negatively affects the land transfer rate. In addition, this policy is most likely to limit land transfers between local acquaintances in the major grain-producing areas. Further evidence indicates that the basic farmland preservation policy has a negative impact on land rentals in general. Considering that land transfers such as exchanges and take-overs are excluded from rental transactions between acquaintances, the policy’s constraints on land use are likely to hinder land rentals between acquaintances, which are market-oriented.Practical implicationsOverall, this study’s analysis suggests that the farmland preservation policy’s constraints on land use rights are likely to result in a major diminishment of the rural rental markets. Under this policy, land that is designated as basic farmland cannot be converted to another use. However, it remains possible to improve the productivity of agriculture through other means. These possible avenues for improvement include enhancing the efficiency of production through expanding the scale of farming operations and developing the social services aspect of agriculture (i.e. the basic farmland preservation policy is likely to realize more social revenue than can be gained from land transfers). Thus, the arrangement of the basic farmland preservation policy in China can be managed in a way that is both economical and reasonable.Originality/valueTo ensure food security, China has enacted several laws and regulations to preserve basic farmland, and it has promoted land transfers to improve farm productivity. Therefore, it is important to understand whether the basic farmland preservation policy restricts land use rights and hinders land transfers that could improve productivity. This study provides empirical evidence showing that the basic farmland preservation policy is actually not conducive to promoting land transfers and that it even discourages the market orientation of land rentals between acquaintances. In dealing with this issue, the Chinese Government should seek to balance the relationship between preserving basic farmland and promoting land transfers.

China's grain security is an increasing global concern. Most researchers argue that land renting-in leads to the cultivation of non-grain products in rural China We use household-level data collected in China to assess the relationship between land renting-in and grain production. Our results indicate that land renting-in positively affects rice acreage, especially when there is less labor available for agriculture. The channel of the effect is that lessees tend to increase the use of machinery in rice production, but not in the production of cash crops because the production of grain crops can be more easily mechanized in rural China. The Chinese government should still pay close attention to the cultivation of non-grain products caused by land renting-in because workers in the production of cash crops may also be easily replaced by new agricultural technologies.
