Decomposition of energy-related CO2 emission over 1991-2006 in China

This paper presents a decomposition analysis of energy-related CO₂ emission in China for the period 1991-2006 divided into three equal time intervals. The complete decomposition method developed by Sun is used to analyze the nature of the four factors: CO₂ intensity, energy intensity, structural changes and economic activity. The results show that economic activity has the largest positive effect in CO₂ emission changes in all the major economic sectors and China has achieved a considerable decrease in CO₂ emission mainly due to the improved energy intensity. However, the impact of CO₂ intensity and structural changes is relatively small. Structural changes only exhibit positive effect to the CO₂ mitigation in agricultural sector, and CO₂ intensity also contributes to the decrease of CO₂ emission in transportation sector. Moreover, a formula about CO₂ mitigation is presented in this paper, which shows that China has made a significant contribution to reducing global CO₂ emission.     

中国养老保险最优缴费率的实证分析——基于贴现因子和劳动增长率差异的分析

从个人效用和社会福利最大化的角度出发,养老保险制度存在着最优的缴费率.最优缴费率与资本产出弹性a、未来效用的贴现因子p、人口增长率n、有效劳动增长率g、个人工资与社会平均工资的比例λ等参数有关.结合中国现实,在其他参数不变的前提下,依据贴现因子和劳动增长率的变动能够形成四组组合模式.模拟结论表明,现行养老保险制度的社会统筹缴费率是符合福利最大化的最优缴费率;现行养老保险制度的个人账户缴费率与实现福利最大化的最优个人账户缴费率相比是偏低的;缴费期的长短与最优社会统筹缴费率的高低成正比而与最优个人账户缴费率的高低成反比;有效劳动增长率的高低与最优社会统筹缴费率成正比而与最优个人账户缴费率成反比.     

Assessing the Reliability of Self‐reported Income Information in Informal Small Business Lending through a Bogus Pipeline Experiment

Coping with asymmetric information plays a major role in successful small business lending. Our purpose is to determine if small business applicants report their income information correctly when requesting a loan. We use a randomised controlled trial bogus pipeline experiment, established during a typical cash‐flow analysis of a bank for small businesses in the Philippines. The bogus pipeline approach is commonly applied in social science and aims to increase the rate of truth telling by informing participants that answers will be verified by a lie detector. The experimental data, which include 243 observations of credit clients that are mainly from the agricultural and food value chain, served to identify asymmetric information. Additionally, debtors’ repayment behaviour for approved loans was observed by the bank. Our results indicate that loan applicants of the treatment group report lower incomes, an effect which is most pronounced in lower income quantile. Our analyses also reveal higher loan delinquencies in the control group.

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.

An application of co-word analysis and bibliometric maps for detecting the most highlighting themes in the consumer behaviour research from a longitudinal perspective

This article presents an application of a bibliometric and visual study of the research carried out on a social science subfield, concretely the consumer behaviour research (CBR), from a longitudinal perspective (period 1966–2008). The study combines performance analysis and science mapping for detecting and visualizing conceptual subdomains. Quantitative and qualitative measures are used in order to identify the most prominent themes. Quantitative data are used to put together very related concepts (themes or clusters of topics), while qualitative indicators (as those based on citations) are used to measure the quality and/or impact of the detected themes. The study also uses bibliometric maps to show in a visual way the associations between the main concepts treated by the CBR community. The maps provide insight into the structure of the CBR, visualize the division of the field into several subfields, and indicate the relationships between these subfields. Co-word analysis is the bibliometric technique used to identify the main themes. All this allows us to quantify and visualize the thematic evolution of the CBR. It also helps to both experts and novices to understand the current state of the art of the CBR and to predict where future research could lead.     

世界石油物探行业发展趋势及中国企业面临的挑战

国际金融危机造成石油公司大幅削减物探投资，对石油物探行业形成巨大冲击。金融危机后，物探作业队伍数量仍处于较高水平，物探市场供给过剩，竞争激烈，物探公司经营困难；大量深海低端船只退出市场，海上物探船走向高端时代；多用户业务投资和收入大幅下降。物探行业的变化给中国石油物探企业带来了巨大挑战。建议中国石油物探公司：1）加强成本管理。理顺流程，加大合力，发挥规模效应，避免重复建设和浪费；加大资源、管理和技术的共享，形成竞争优势；提高公司整体管理水平和项目运作效率。2）重视对国家石油公司和国际大石油公司这两个客户群体的细致分析和研究。3）培育多用户项目运作能力。通过与经验丰富的公司的合作，逐步实现独立自主运作多用户项目。4）大力推进技术创新。将科技投入作为加快企业发展的战略性投入，加强企业技术创新人才的培养和高端技术人才的引进，理顺物探企业技术创新管理体系，提高技术创新的投入产出率。
