基于数据包络(DEA)分析的京津冀地区环境绩效评估研究

提高资源环境绩效是区域生态环境治理的核心与关键。在构建环境绩效评估指标体系的基础上，运用数据包络分析模型（DEA）测度并分析2005-2015年京津冀地区静态环境绩效水平。利用Malmquist指数动态分析法将环境绩效分解为技术效率变化指数和技术进步指数，并探讨分解指标对环境绩效的相对贡献。结果显示：京津冀地区环境治理投入与产出水平均呈现逐年上升趋势；北京和天津的总体环境绩效水平要远高于河北，2005-2011年京津冀地区的环境绩效水平排序为北京、天津、河北,2012-2015年京津冀地区的环境绩效水平排序为天津、北京、河北（2013年除外）。河北省环境绩效水平较低的主要制约因素是技术进步缓慢与全要素生产率偏低。Malmquist指数呈现出一定的波性，这主要是由技术变化指标波动所致。最后，就如何提升京津冀地区环境绩效水平，提出相关对策建议。     

Chinese relationship management: a qualitative study of banking in New Zealand

This study investigates the relational factors and motivations of Chinese migrant consumers towards financial service providers in New Zealand. Using convergent interviews, a deeper understanding is developed of immigrants’ relational behaviour with service providers. These relationships with service providers are significantly influenced by traditional Chinese values and guanxi and relational embeddedness plays an important role in how they are developed. The research contributes a better understanding of the interplay between Eastern and Western cultures in service relationships among immigrant groups. A general theory of the Chinese perspective of customer relationship management is developed. The implications for how marketing practitioners manage their relationships with migrant customers are explored.     

Residents’ perceptions of airport construction impacts: A negativity bias approach

Airports have significant implications for regional and local tourism development, so their impacts need to be assessed. Based on in-depth interviews with local residents, this study examined the effects of an airport development project in Mexico. Negativity bias theory was adopted as a theoretical framework to gain a fuller understanding of host communities' perceptions. In accordance with this theory, even though the economic impacts of the airport's construction are recognised as positive, its environmental and social effects on locals' everyday lives are perceived more negatively. As a result, most locals interviewed do not support the airport project. This is because, in line with negativity bias theory, when perceived negative impacts outweigh positive ones, a holistic evaluation that integrates negative and positive events will ultimately be unfavourable. Practical implications in terms of public consultation, perceived impacts and tourism development are discussed.     

Effects of perceived constraints and negotiation on learned helplessness: A study of Chinese senior outbound tourists

Learned helplessness is an important psychological construct that may influence senior tourists' subjective wellbeing while travelling. Employing a mixed-method approach and a multi-sample design, this study examines how Chinese senior outbound tourists’ perceived travel constraints and negotiation efforts affect learned helplessness in outbound travel. We identified four perceived constraints (perceived incapability, lack of suitable travel agencies and services, lack of information and personal support, and complex travel decision-making) and three negotiation strategies (seeking family support, physical/health preparation, and learning). Multiple regression analyses showed that among the four perceived constraints, only perceived incapability increased learned helplessness significantly; conversely, negotiation in general reduced learned helplessness. However, not as expected, negotiation was not founded to be a moderator between perceived constraints and learned helplessness. Theoretical and practical implications are also discussed.     

天津市美丽乡村建设模式及效益评价体系构建

［目的］“美丽乡村”建设是全面推进现代化农业发展，加强生态文明建设的重要举措。归纳天津市“美丽乡村”建设模式，构建效益评价体系，并对乡村建设效益进行评价，以期为实现该市乡村建设奋斗目标提供理论参考。［方法］通过调研天津市乡村发展现状，在归纳总结该市乡村建设模式的基础上，采用层次分析法和综合加权法，从社会、经济和生态效益3个层面构建了美丽乡村建设效益评价体系，并对“美丽乡村”建设项目实施前和2016年的建设效益进行评价。［结果］（1）天津市乡村建设模式可分为4种类型，分别为休闲旅游、文化传承、高效农业和环境整治型，涌现出了一批各具特色的典型村落，发展较为迅速。（2）从启动美丽乡村建设项目止2016年，该市乡村建设取得了明显的生态、社会和经济效益，评价分值相比项目实施前分别提高了6513%、4167%和3621%，综合效益评分提高了50%。［结论］天津市美丽乡村建设取得了较好的成效，其他村庄在建设过程中，可参考已建设成型的典范，因地制宜，选择适合规划的发展模式。已建设成型的村庄发展空间还很大，仍需不断缩短城乡差距，推动美丽乡村的可持续健康发展。     

SHIFTING BOUNDARIES IN ECONOMICS: THE INSTITUTIONAL COGNITIVE STRAND AND THE FUTURE OF INSTITUTIONAL ECONOMICS

This paper aims at contributing to the debate on the future of institutional economics and of the field as a whole by starting from the literature that discusses the relationship between Old‐Original Institutional Economics and New Institutional Economics. It suggests that the process of reunifying OIE and NIE (and evolutionary economics) prompted by part of the literature could be improved by the contribution of the Cognitive Institutional Economics. The paper follows a two‐stage pathway: first, it frames the debate on the relationships between NIE and the OIE and it concentrates on a subset of the literature that shows that NIE's recent developments complicate the distinction between NIE and OIE, and it explores the possibility that NIE and OIE may merge so that an amalgam of NIE, OIE and Evolutionary Economics becomes the next economic paradigm. Secondly, the paper argues that a step forward in the direction outlined by the literature has been made by CIE, which is a research stream that developed from cross‐fertilization among NIE, OIE and the Hayekian contributions to the analysis of institutions. In the concluding remarks, the possible emergence of a single institutional paradigm is discussed in the light of the literature about change in economics.

Feed use intensification and technical efficiency of dairy farms in New Zealand

In recent years, the traditionally pasture‐based dairy farms in New Zealand have become more intensive by using higher proportions of supplementary feed. This trend has been attributed to a range of factors, such as productivity enhancement, overcoming pasture deficits and the improvement of body condition scores. However, there is a lack of knowledge as to how feed use intensification affects the technical efficiency of dairy farms in New Zealand. This paper addresses the research gap by estimating the impact of feed use intensification on the technical efficiency of New Zealand dairy farms, using a fixed effects stochastic production frontier model and a balanced panel of 257 farms from 2010 to 2013. The empirical results show that technical efficiency on New Zealand dairy farms is positively and significantly influenced by feed use intensification, herd size and milking frequency.     

Airline new route selection using compromise programming - The case of Taiwan-Europe

The decision to launch a new route has a huge effect on the outcomes of airlines in the market. In order to find potential destinations for airlines, this paper utilizes a compromise programming method for selecting direct flight routes. The selection framework comprises two objective functions, with one maximizing total revenue and the other minimizing total cost. A case studying Taiwan-European region destinations is interpreted in the analysis. The results indicate that four potential routes, including Madrid, Milan, Munich and Zurich should be added to the airlines’ service destinations. Therefore, this research suggested that the airport authority could apply incentives scheme to attract carriers to open new routes and add flight frequencies to strengthen its competitiveness.     

Vegetarian Utopias: Visions of dietary patterns in future societies and support for social change

The current study draws on the collective futures framework to examine how visions of future societies where most people consume plant-based, vegetarian or vegan diets are related to current support for social change towards plant-based diets. Participants were 506 university students in Aotearoa New Zealand invited to imagine a society in 2050 where most individuals consume a plant-based, vegetarian, or vegan diet. A thematic analysis was conducted on responses to an open-ended item asking how these future societies would be different to today. Participants reported a variety of potential positive and negative outcomes for individuals and wider society. Subsequent analyses of attitudes scales investigated the relationships between the collective dimensions of plant-based future societies and support for policies to promote plant-based diets. For a vegetarian future, the strongest predictor of current support for social change was the expectation that widespread vegetarianism would reduce societal dysfunction. For a vegan future, the strongest predictor of support for social change was an expectation of increased warmth in a vegan society. Implications for theory and advocacy are discussed.
