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.     

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.     

Antecedents and consequences of hotel customers’ psychological ownership

This study aims to broaden the current knowledge on the antecedents and consequences of customers’ psychological ownership (CPO) from new perspectives in the hotel context. Specifically, this study investigates how self-image congruity and functional congruity affect CPO through impression in memory based on self-congruity theory and also examines two types of customer engagement—customers’ social influence engagement and knowledge-sharing engagement—as new CPO outcomes. Using survey data collected from 433 Chinese hotel customers, this study finds that self-image congruity positively predicts CPO partially through impression in memory, whereas functional congruity positively influences CPO fully through impression in memory. Moreover, the findings indicate that CPO significantly drives customers’ social influence engagement and knowledge-sharing engagement. This study contributes theoretically to the CPO literature by further developing its linkages with congruity perceptions and customer engagement. Practical implications of the findings can help hotel managers effectively promote CPO and customer engagement.     

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.     

归因偏差视角下旅游行为失范成因研究

游客旅游行为失范时有发生,威胁着旅游资源与环境安全。心理归因影响个体行为逻辑,归因偏差是解释心理归因的经典理论。本文引入归因偏差理论,采用实证方法探究旅游行为失范背后的归因偏差因素,为减少旅游行为失范提供心理学依据。研究发现,归因偏差能够引致旅游者心理认知偏差,后者直接引发和助推旅游行为失范。心理环境和群体心理对引致旅游者的心理认知偏差和行为失范具有显著作用,归因偏差成为旅游者弱化旅游行为失范结果的心理屏障,可激发或促进旅游行为失范的发生或持续。研究认为旅游地可从完善硬件监控、控制游客流量、强化失范行为负面教育、发挥在场监督作用等方式削弱归因偏差效应。

Is the system reliability profitable for retailing and consumer service of a dynamical system under cross-price elasticity of demand?

Retailing strategy is one of the most crucial factors for industries. A proper retailing strategy can help to enhance consumer service and increase the industry's profit. An improved approach to retailing is suggested in this research to deliver superior customer service while maximizing profits in a dynamic system. The study analyzes a retailing strategy for a demand with cross-price elasticity upon the retail price. A product's cross-price elasticity and the system reliability are critical factors in retailing. Understanding the cross-price elasticity of demand between products helps retailers to make pricing decisions that maximize profits by maintaining demand. Imperfect products are produced due to an imperfect production system. The imperfect ones must be adjusted with some costs to make them perfect for better retailing. The system failure rate is crucial for retailing under cross-price elasticity of demand patterns. Production system reliability, cross-price elasticity of demand, and consumer service are all essential factors that can impact a company's success in the market. The production rate is considered time- and system failure rate-dependent. Contradictory to the literature, a dynamical system is proposed for improved retail management, which is solved using the Euler-Lagrange theory. Finally, one can achieve the expected maximum profit for this retail system with optimum selling prices for different products by reducing the system failure rate. Some numerical illustrations with graphical representations are provided to validate the current study. Numerical examples show that applying cross-price elasticity of demand for more than two identical products provides 35% more profit for the retail industry than a single type of product.
