农业绿色发展路径及其“十四五”取向

随着农业资源环境问题的凸显,绿色发展成为农业发展的主流。基于对农业绿色发展关键要素的界定,提出农业绿色发展的三个阶段:去污,即农业生产过程的清洁化;提质,实现产地绿色化和产品优质化;增效,绿色成为农业高质量发展的内生动力。近年来,农业绿色发展取得了一定成就,但也存在政策分散、数据基础不牢、农业补贴制度改革进展缓慢、行政执法“一刀切”等问题。“十四五”时期,应以绿色发展驱动农业高质量发展,通过抓落实提高政策实效;注重摸清家底,摒弃部分无数据支撑的量化目标;加强对执法和行政的督察巡查,对政策执行过失加大问责力度;不断深化农业支持保护制度,向绿色生态方向改革。

水生态系统服务供需视角下的水网乡村 适应性规划策略——以吴江张鸭荡片区为例

苏南乡村地区一直是中国乡村建设的先行区域，特殊的纵横交错的水网结构构成了一个错综复杂的系统，呈现出其他地区不具有的复杂性和生态特殊性。随着城镇的扩张，乡村的发展建设使其水网空间的平衡发展面临极大的挑战。传统单一静态的规划方法逐渐显示出无法适应经济、社会等发展要求的缺陷。苏南乡村地区以水为核心，从水生态系统服务供需关系的视角下探究水网乡村的适应性规划策略更加适应当前的乡村现状和需求。以传统水网乡村空间形态转译为基础，建立水生态系统供需服务评估体系，在评估水生态系统服务供需能力的基础上，分析供需分异模式及供需矛盾。从构建乡村水域空间生态格局、乡村水域空间功能分区规划，以及乡村水域空间多情景预判3个方面，提出苏南水网乡村的适应性规划策略，并为水网乡村的生态实践提出新思路。     

Circular business model implementation: A capability development case study from the manufacturing industry

Circular business models (CBMs) have huge potential to deliver economic, social, and environmental benefits, but CBMs have yet to be implemented widely in industrial settings. One reason is that they are often presented as one-size-fits-all solutions, but this is misplaced because product-specific criteria and company capabilities determine the correct choice and implementation of CBMs. Therefore, the purpose of this paper is to investigate how CBM selection and capability development facilitates the implementation of CBMs. For this purpose, we have adopted a qualitative research approach and undertaken 25 explorative interviews in three large Swedish manufacturing companies. In this paper, a CBM implementation framework consisting of two parts has been developed. The first part addresses the choice of the appropriate CBM based on tactical configurations. The second part provides a capability development path by explicating underlying routines that need to be progressively developed in order to move smoothly to more advanced CBMs.     

中国农业农村发展七十年:成就、经验与展望——中国农业经济学会第十次会员代表大会暨2019年学术研讨会综述

2019 is the 70 th anniversary of the founding of the people’s Republic of China and the key year for implementing the rural vitalization strategy.Summarizing the great achievements made by agriculture and rural areas in the past 70 years will have an important theoretical value for promoting the modernization of agriculture and rural areas and the strategy of rural revitalization.Under such circumstances,the 10 th member congress and 2019 academic seminar of CAAE was successfully held in Beijing.The key to promote rural revitalization lies in deepening rural reform,focus on the property right system and market-oriented allocation of factors,and establish a system and mechanism of free circulation and equal exchange between urban and rural areas.In order to promote the organic connection between small-scale peasant and the modern agriculture,it is necessary to speed up the development of agriculture social service industry.Finally,it is suggested to adhere to the two-wheel drive of rural revitalizationand new urbanization,promote the effective coverage of rural public services,and improve the rural governance mode of combining autonomy,rules of law and virtue.     

Exploring the motivations to use online meal delivery platforms: Before and during quarantine

Online meal delivery platforms (OMDPs), like UberEats, have received more attention since quarantine was established to prevent the spread of COVID-19. The research into antecedents of satisfaction and continuous usage intention for OMDPs, in general, is under researched. The current study compared the antecedents of satisfaction before quarantine to the antecedents during quarantine through the lens of Expectation-Confirmation Theory. Through multiple regression analyses, the researchers found that before quarantine, sharing economy ethos, price-value, food quality, ease of use and confirmation of beliefs had a significant impact on satisfaction while during quarantine, food quality, service speed, ease of use, and confirmation of beliefs were significant. Practical and theoretical implications are discussed.     

服务业内部结构异质性演化与行业发展差距研究——基于全要素生产率视角下的分析

基于1990—2017年行业面板数据，采用超越对数生产函数对服务业各细分行业TFP增长率进行分解和测度，揭示我国服务业内部结构生产率演化进程及其异质性现象，并采用可导性对数方差分解法、VAR协整模型和误差修正模型（VECM）考察TFP及其构成部分对服务业行业发展差距的贡献度，评估其异质性作用于行业发展差距的长短期效应。研究发现，在服务业内部结构演化过程中，TFP、技术进步和技术效率改进呈逐步下降趋势，其中技术进步是推动TFP增长的核心，规模效率改进发展水平一直滞后，配置效率改进在服务业发展初期较为滞后，但水平逐步提升；生产性和生活性服务业行业间TFP及构成部分异质性在演化过程中呈下降趋势，且生活性服务业行业间异质性程度要小于生产性服务业，行业间异质性变化幅度最大的是规模效率改进，技术效率改进异质性波动程度最小；TFP异质性是造成行业间发展差距扩大的主要原因，其中技术效率改进是主导因素，且该效应的发挥只有在长期具有显著性。     

Who is left behind? Exploring the characteristics of China's broadband non-adopting families

China has made significant progress in broadband development. As of September 2018, 95% of China's population was covered by 4G networks. However, our estimates show that nearly 30% of China's families did not use broadband that year. This study attempts to investigate the characteristics of China's broadband left-behind families. Overall, consistent with the findings for other countries, families with a lower socioeconomic status are more likely to be broadband non-adopters. In the information society, older, poorer, rural and less educated families are left behind. It is recommended that the Chinese government shift from a top-down investment-driven policy to a user-centered demand-driven policy to address the digital divide.     

新一代车险“理赔难”

保险作为现代服务行业之一,服务质量问题始终贯穿其中。其中,“理赔难”的现象层出不穷。从1929年11月在中国上海成立第一家保险公司太平保险,到目前保险行业已发展90余年,中国的车险理赔还难吗?依然难,只是难点变了,老矛盾得到部分解决,新矛盾层出不穷,唯独对理赔服务质量的评价参差不齐是永恒的。
