Sustainable Production: Practices and Determinant Factors of Green Supply Chain Management of Chinese Companies

This paper explores the green supply chain management (GSCM) of companies based in the Yangtze River Delta, China. The companies' overall GSCM practice level (L_GSCM) is measured by using the data from 165 valid respondents in a questionnaire survey conducted during April and May 2009. The relationships between L_GSCM and the classified determinant factors are analyzed. It is indicated that Chinese companies are still at a preliminary stage of GSCM practices. Their environmental management in cooperation with external members of the supply chain is very marginal. A company's L_GSCM is significantly and positively associated with the external pressures from regulatory, domestic clients and business competitors. As an internal factor, a company's learning capacity greatly determines L_GSCM. We also confirm that the internal factors function as intermediate variables of external pressures in influencing a company's GSCM. A company's environmental management capacities will be strongly enhanced by frequent internal training of employees to increase its involvement in GSCM practices.

Knowledge acquisition using psychotherapy technique for critical factors influencing construction project layout planning

The positioning of equipment on a construction site may change in different construction phases, different environments, and different types of end products, which greatly influence the decision of the site planning engineer who seeks to maximize the construction efficiency by minimizing the friction from the site layout. This study aims to acquire and analyze site planning experts' knowledge on critical factors influencing the construction layout planning using a psychotherapy technique. Through an open‐structured interview survey and cluster analysis, 125 core factors influencing the site layout plan were analyzed and categorized into a database.     

The criticality of risk factors in customer relationship management projects

Customer relationship management (CRM) remains an area of considerable interest in contemporary project management literature, due to its association with high failure rates. This research examined the criticality of four risk factors. Quantitative data analyzed using PASW17 were collected from a sample of 250 CRM project practitioners. Although we found strong evidence to support the focus on these risk factors, which include “user training,” “top management support,” “business strategy and technology alignment,” and “effective project feedback,” the authors found that, although some risk factors may be identified as “critical,” their criticality is dependent on the context of the project.     

Forecasting Success on Large Projects: Developing Reliable Scales to Predict Multiple Perspectives by Multiple Stakeholders Over Multiple Time Frames

Our aim is to develop a set of leading performance indicators to enable managers of large projects to forecast during project execution how various stakeholders will perceive success months or even years into the operation of the output. Large projects have many stakeholders who have different objectives for the project, its output, and the business objectives they will deliver. The output of a large project may have a lifetime that lasts for years, or even decades, and ultimate impacts that go beyond its immediate operation. How different stakeholders perceive success can change with time, and so the project manager needs leading performance indicators that go beyond the traditional triple constraint to forecast how key stakeholders will perceive success months or even years later. In this article, we develop a model for project success that identifies how project stakeholders might perceive success in the months and years following a project. We identify success or failure factors that will facilitate or mitigate against achievement of those success criteria, and a set of potential leading performance indicators that forecast how stakeholders will perceive success during the life of the project's output. We conducted a scale development study with 152 managers of large projects and identified two project success factor scales and seven stakeholder satisfaction scales that can be used by project managers to predict stakeholder satisfaction on projects and so may be used by the managers of large projects for the basis of project control.

Time-varying comovement and changes of comovement structure in the Chinese stock market: A causal network method

The driving force for the comovement in stock returns is a long-standing debate between classical asset pricing theory and behavioral finance theory. It has become critically important recently for understanding systemic risk and risk contagion in the market. In this study, we propose complex networks enabled new methods to measure the causal comovement of individual stocks and the comovement structure of the market, which facilitate the examination of all kinds of hypotheses of comovement theories in a unified framework. Using a sample of the Chinese stock market from Jan. 1, 2006 to Dec. 31, 2016, we find that the degree of comovement generally intensifies over time, with a drastic increase from 2011 to 2015, while the comovement structure of the market changes with different market situations. Most importantly, our study reveals the driving force of causal comovement among individual stocks; that is, sentiment-based factors related to the market index indeed induce excess causal comovement in returns beyond that can be justified by fundamental factors including beta coefficient, book-to-market ratio, liquidity, profitability and volatility. Our study also reveals the determinants of comovement structure, which are attributable to the change of investors' behaviors in different periods. It turns out that investors in the Chinese stock market care about risk-return relationship in normal periods, while they seem to care only about risk in crisis periods.     

农户生态耕种采纳行为影响因素实证研究——基于江西省1488份农户的调查数据

基于江西省11市47县(区)1488份农户调查问卷数据,运用多元有序Logistic模型,分析并探究农户生态耕种采纳行为的影响因素。结果表明:家庭总人口具有显著的负向影响;兼业程度、农业收入占比、家中是否有村干部、是否参加新农保、是否有农业补贴、是否为家庭农场、是否加入合作社、近年耕地质量变化、相关信息获取难度等9个变量具有显著的正向影响。农户对生态耕种行为采纳的均值只有4.74项,总体偏低,生态耕种行为有待推广与应用。论文探究了农户生态耕种采纳行为的影响因素,为生态耕种的推广、实现耕地资源的可持续发展、激励农户生态耕种政策的制定提供了参考。
