重大水利工程项目决策社会稳定风险评估中公众参与成熟度的影响路径

重大水利工程项目决策社会稳定风险评估中,公众是重要的参与主体,个体间生活环境、知识背景及心理素质的差异性会直接影响稳评结果。公众参与成熟度是公众参与的衡量要素,由能力成熟度和心理成熟度两个方面构成。从能力与心理两个角度设计调查问卷,运用结构方程模型,探究内部影响路径。结果表明,公众参与心理成熟度直接影响能力成熟度,而能力成熟度又通过参与意愿影响着心理成熟度,两者间存在相互影响的关系。政府可以通过开展道德素质教育,改善公众参与动机,以提高公众参与心理成熟度及能力成熟度,最终整体提高公众参与成熟度,保证稳评工作的质量,提升重大水利工程项目决策科学性。     

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.     

Social media and sustainable purchasing attitude: Role of trust in social media and environmental effectiveness

The role of social media in promoting sustainable attitudes is currently understudied. Underpinned by social learning theory, this study unveils the effect of social media usage and browsing on sustainable purchasing attitude, the underlying mechanism, and the boundary condition. Drawing on a sample of 693 experienced respondents analyzed using structural equation modeling, this study reveals that social media usage and browsing have a significant positive association. Both constructs significantly impact sustainable purchasing attitudes with complementary partial mediation of the drive for environmental responsibility. Further, trust in social media and perceived environmental effectiveness significantly moderate the relationships belongs to the browsing and drive for environmental responsibility. Contrary to the theorization, moderating constructs cannot substantially impact the proposed associations of social media usage. In this manner, the present research is innovative and provides valued knowledge to comprehend social media's role in encouraging sustainable attitudes.     

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.     

基于社会网络视角的科研合作网络结构及特性分析——以战略性新兴产业领域为例

战略性新兴产业是近几年新出现的研究热点,对其科研合作网络的研究,有助于探究该领域的科研合作现状与发展趋势。基于社会网络分析方法,以中国知网(CNKI)作为数据来源,构建了战略性新兴产业领域作者合作网络、关键词共现网络、作者-关键词耦合网络及机构合作网络,对合作网络的结构及特性等进行了分析。结果表明:战略性新兴产业领域论文合著率基本呈上升趋势,但该领域整体合作仍较为松散,存在较多的小团体;合作网络具有小世界和无标度特性,具有较大影响力的节点作为合作网络的中心,影响着网络内的学术交流和科研工作的开展。     

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。
