Green multi-tier supply chain management: An enabler investigation

Stakeholder pressure, from actors including regulators, consumers and non-governmental organizations, has made organizations more responsible for poor environmental performance of their direct and sub-suppliers. Thus, green multi-tier supplier management (GMSM) has become an emergent topic. Yet it is still unclear how to enable GMSM practices effectively, i.e. how to enable sub-suppliers' environmental performance improvement. To help address the gap in the literature, this paper aims to identify enablers for sub-suppliers' environmental performance improvement, and it further applies a Decision-Making Trial and Evaluation Laboratory (DEMATEL)-based case study method to evaluate inter-relationships among these enablers and improve the focal company's GMSM practices, by using action research (AR) method principles. The data analysis and discussion with a follow-up evaluation after two years provided insights for the successful implementation of GMSM. The results show that top managers’ support from the organizations is a prominent and necessary foundational enabler. An interesting observation is that close proximity of supply chain members is regarded as a very prominent enabler. Evaluation and feedback on these enablers two years later found that the enabler mapping was beneficial, allowing them to address the most influential enablers, and thus the GMSM practices of the focal company has been highly improved. This paper concludes with directions for further research.     

中国—荷兰中欧班列货源结构时空演化研究

欧盟一直是我国最重要的贸易合作伙伴之一,荷兰则是我国在欧盟的前三大贸易伙伴之一,中荷贸易关系是中欧贸易关系中重要的一环,中欧班列的区域货源结构对中欧班列功能定位和发展规划意义重大。为明确中荷贸易背景下货源结构动态演化过程、特征及机制,在模糊C均值基础上,结合邻接矩阵对聚类分析结果进行修正,将各离散点货源数据进行合并聚类,剖析其时间和空间层面的演变及原因,探究货源结构时空演化趋势。结果表明:2014—2018年,中荷之间货源数量整体呈上升趋势,货源时空布局呈现空间集聚效应,表现为“由整到散”“西高东低”的演化态势。最后提出相关政策建议。     

Simplified Jackknife Variance Estimates for Fuzzy Measures of Multidimensional Poverty

In this paper, we present a practical methodology for variance estimation for multi‐dimensional measures of poverty and deprivation of households and individuals, derived from sample surveys with complex designs and fairly large sample sizes. The measures considered are based on fuzzy representation of individuals' propensity to deprivation in monetary and diverse non‐monetary dimensions. We believe this to be the first original contribution for estimating standard errors for such fuzzy poverty measures. The second objective is to describe and numerically illustrate computational procedures and difficulties in producing reliable and robust estimates of sampling error for such complex statistics. We attempt to identify some of these problems and provide solutions in the context of actual situations. A detailed application based on European Union Statistics on Income and Living Conditions data for 19 NUTS2 regions in Spain is provided.

Prioritizing destination attributes for optimal resource allocation: a study of Chinese tourists visiting Britain

ABSTRACT

This study assesses the importance, performance, and the interrelationships of key destination attributes for marketing managers to prioritize resource allocation. A three-dimensional analysis of importance–performance–impact-analysis (IPIA) factors, based upon a survey sample of 275 Chinese tourists to Britain and an expert panel interview with 10 destination marketing managers is presented. Data analysis was based upon a mix of multi-criteria decision-making methodologies, the Decision-Making Trial and Evaluation Laboratory (DEMATEL) method and the Analytic Network Process (ANP) method. The framework can be applied to prioritize resources allocation to improve customer satisfaction in other contexts, such as a sector or a specific business.     

河南省中牟县低碳农业发展评价研究

[目的]以河南省中牟县为研究对象,通过评价中牟县低碳农业发展水平,试图探索适合中牟县低碳农业的发展道路,并为当地低碳农业发展提供参考依据。[方法]文章采用统计数据分析法、调查统计分析法以及层次分析法。搜集分析2005~2015年中牟县低碳农业相关数据,构建低碳农业系统发展评价指标体系,得出中牟县低碳农业历年综合得分。[结果]中牟县低碳农业发展呈逐年上升趋势,2005~2015年年均增长率14.50%。其中,农业社会因素、农业经济因素发展得分高于低碳农业综合得分,年均增长率分别为23.90%、25.20%,但农业资源和环境方面发展缓慢,年增长率分别为2.30%、-1.40%。[结论]中牟县低碳农业呈现稳固上升发展态势。2005~2015年中牟县低碳农业数据分析表明,农业社会和经济系统的发展是中牟县低碳农业发展的重要推动力;而农业资源的投入、农业环境问题已成为中牟县低碳农业发展的主要阻碍制约因素。

Modeling green vehicle adoption: An integrated approach for policy evaluation

This article employs an integrated discrete-continuous car ownership model to jointly forecast households’ future preferences on vehicle type, quantity and use, and to estimate greenhouse gas (GHG) emissions. The model system is estimated on a dataset collected from a web-based stated preference survey conducted in Maryland in 2014. The data contain vehicle purchase decisions and sociodemographic information of 456 households who were requested to state their future preferences over a 9-year period (2014–2022). In each time period, a respondent is faced to four alternatives that include the current vehicle, a new gasoline vehicle, a new hybrid electric vehicle, and a new battery electric vehicle. Intertemporal choices between conventional and “green” vehicles such as hybrid and electric cars capture dynamics in vehicle purchase decisions. Short run and medium-long run situations were predicted and compared based on the first 4-year data and the entire 9-year data of the dynamic panel. Vehicle GHG emissions were calculated correspondingly. We find the introduction of “green” vehicles makes a positive impact on car ownership and use, especially in a medium-long run. Two “green” taxation policies, gasoline tax and ownership tax, were proposed and their impact on vehicle use and emission reductions was evaluated. Results indicate that: (a) gasoline tax is a more effective way to reduce vehicle miles traveled and GHG emissions and (b) gasoline tax makes a higher impact on car use and emission reductions in the medium-long run, while ownership tax makes a higher impact in the short run.
