环境与耕地约束下的城镇化效率及其发展模式探因

[目的]考虑环境和耕地约束,构建了城镇化效率测算指标体系,测算并分析我国2000~2014年区域城镇化效率,并且从城镇化发展模式与产业结构分布形态2个角度探索区域城镇化效率差异的机理。[方法]以"工业三废"和耕地面积减少量作为非合意产出,构建了由11个指标组成的投入—合意产出—非合意产出指标体系,进而利用优化ISBM模型测算了2000~2014年我国区域城镇化效率,并利用谱系聚类方法分析了其梯队层次特征。[结果]我国各省域城镇化效率总体较低,绝大多数省域处于效率缺损的状态;各省域城镇化效率表现为明显的5个梯队层次,不同区域、不同梯队省域城镇化效率存在明显差异,总体呈现出东、中、西依次递减的格局,并且省域之间城镇化效率差距自2000年以来呈不断缩小的趋势;东部地区城镇化效率较高,总体上城镇化与产业结构之间相互协调,城市群发展程度高而使得城市之间的分工合作程度高;中西部地区城镇化效率相对较低,产业结构对经济的支撑作用相对较弱,城市体系断层明显,城市群带动作用弱。[结论]我国区域城镇化效率总体较低且不平衡,这在很大程度上取决于城镇化模式和演进机制,区域之间的城镇化效率差异体现在产业结构层次、城市集聚方式以及劳动力转移方式等方面。     

Pricing a rural development program: uncertainty,indifference, and protest behaviors

This article presents an econometric approach to modeling uncertainty, unwillingness to pay, and protest behavior in contingent valuation studies. For that purpose, a mixture model with sample selection is developed for a multiple‐bounded uncertainty elicitation format. The proposed theoretical framework is applied to evaluate the social welfare impact of implementing a sustainable rural development program. Results show that a “naive” analytical approach that excludes protesters from the analysis would result in significantly higher willingness to pay estimates for those individuals who favor the implementation of the program and agree to reveal their true reservation prices.     

Can Marketing Help in Tackling Food Waste?: Proposals in Developed Countries

One third of food destined for human consumption is wasted globally, and much of the food waste that comes from high-income or developed countries is caused by poor marketing practices, consumer behavior, and consumption patterns. The present study focuses on developed countries to propose some marketing actions that could help in reducing food waste. A comprehensive analysis was carried out for each marketing variable, to provide a snapshot of actions and proposals that are being developed. Our study highlights the relevance of marketing in contributing to reduce food waste, through the removal of “Buy one, get one free” sales promotions, clarifying date labeling, or raising food waste awareness campaigns. The main contribution of this study is the proposal of marketing actions that help in tacking food waste.     

The effects of perceived value on loyalty: the moderating effect of market orientation adoption

This paper aims to identify the moderating effect of service firms’ adoption of market orientation on key variables of consumer behavior, namely perceived value and loyalty. The study took a business-to-customer perspective. First, the adoption of market orientation was measured, from the firm’s point of view. Second, customer perceptions were analyzed, using the two variables perceived value and loyalty. The sample comprised 100 service firms and 572 of their customers. The present work provides original insights, identifying that the effect of perceived value on loyalty depends on other variables external to the consumer, such as the market orientation approach.

手工类非物质文化遗产的保护性开发研究——以广东东莞千角灯为例

手工艺类文化遗产是非物质文化遗产的一个重要的类别,该类遗产是技艺、艺术、历史的文化载体,以其高超精巧的制作技艺为精髓,表现为手工技艺传承人的能力,在历史变迁中极易失传。本文选择手工艺类非物质文化遗产为突破口,以广东省国家级第一批非物质文化遗产东莞千角灯为例,探讨手工艺类非物质文化遗产保护的本质、意义和开发策略,以期对同类别及其他非物质文化遗产保护提供借鉴和参考。

Measuring Corporate Environmental Performance: A Methodology for Sustainable Development

Assessing corporate environmental performance (CEP) that is both comprehensive and consistent with sustainable development both for society and companies, while at the same time taking heed of the facts and interests of each stakeholder, is not a simple feat. Due to the multidimensional character of the sustainability concept, several questions must be considered in the evaluation process: (i) the qualitative nature of indicators and the complexity of developing a synthetic index; (ii) the difficulty of choosing properly statistical techniques for aggregation and (iii) the difficulty of introducing stakeholders’ preferences in the assessment models. This paper is an attempt to address this challenge by developing a framework for the assessment of CEP, based on the application of a fuzzy multi‐criterion decision‐making (MCDM) method. To achieve positive scores in a CEP assessment, an organization should be strategically committed and engage in environmental management and governance structures that are translated into good results in terms of both engagement and operational performance. Unless such premises are explicitly incorporated into the assessment criteria, the results would reveal that the CEP measurement could not be brought into a line with an earnest ambition of achieving true sustainable development.

Influence of Social Media over the Stock Market

This research analyzes investors’ activity through social media and these media's influence over the Chicago Board Options Exchange Market Volatility Index (VIX) using a logit model and a fuzzy‐set qualitative comparative analysis (fsQCA). The logit results show that social media sentiment influences stock markets. Meanwhile, the fsQCA results show that the investors’ profile is important for explaining how social media influence the stock market. Particularly, holding period combined with experience in technical investors contributes to avoiding a raise in market risk, whereas for nontechnical investors message sentiment and experience form the combination that contributes to avoid a raise in market risk.     

Assessing ethical behaviours in the Spanish banking and insurance industries: evidence and challenges

This study aims to improve understanding of the ethical nature of the relations in two labour-intensive industries to facilitate the creation of an ethical culture. For this purpose, the authors first review literature related to the main influences on ethical behaviour, then perform an empirical analysis of those factors using a hierarchical stepwise regression of a database of 525 banking and insurance employees. Contrary to expectations, leadership has a less important effect on ethical behaviour than other organizational factors. The results reveal several implications for improving the management of ethical behaviour in these industries.
