Quantitative Analysis of Foreign Trade and Environmental Efficiency in China

This article analyzes the relationships among trade, the economy, and environmental quality in China. First, in the context of these relationships, the Super-SBM model is used to calculate the environmental efficiencies of thirty Chinese provinces and cities to obtain the degrees of regional disparity. Second, China’s provincial panel data from 2003 and 2012 are used to establish an influential factor indicator system of environmental efficiency. A section-weighted fixed effect model then provides insights about influential factors such as spatial heterogeneity. Third, the article establishes a variable coefficient model to identify the relationships among the objects of the study and divides the Chinese regions into four types. The suggestions include enhancing environmental and business regulations to ensure equilibrium between trade, the environment, and local economies.     

An economic evaluation of market development programmes for US dairy products

‘This study measured the effectiveness of US dairy export promotion programmes on increasing foreign demand and enhancing producers’ revenues. An import demand equation based on panel data was used to test whether export promotion has a positive and significant impact on US dairy exports. The effects of various promotion scenarios on the dairy market were then simulated, and benefit–cost ratios (BCRs) for these programmes were estimated. There were three key findings. First, the combined effort of public and private dairy export promotion expenditures had a positive and statistically significant impact on demand for US dairy products in the world market. The findings indicated that export promotion stimulated total dairy exports by 4.14 billion pounds, on average, per year, which represented 55.8% of total exports. Second, US dairy export promotion has been highly profitable for the nation’s dairy farmers. The calculated BCRs, based on assumed elasticity of supply, ranged from a low of 8.54 for the most elastic assumption to a high of 30.12. Third, from an optimality standpoint, dairy farmers are underinvesting in export promotion. The marginal BCRs ranged from a low of 3.79 to a high of 15.22, which means that, at the margin, increasing export promotion expenditures would be profitable for dairy farmers.

技术进步对中国就业影响的实证研究

选取1978—2008年中国30个省市的面板数据,运用DEA方法测算中国的全要素生产率及其分解项:技术变化与技术效率,并使用ARDL模型实证分析技术效率和技术变化对就业的影响。研究发现:技术效率无论是长期还是短期都对就业具有显著的抑制效应,但在短期中,技术变化当期对就业没有显著影响;而滞后期技术变化的改善也会对就业人数的增加产生抑制效应,同时,在长期中,技术变化对就业有着显著的促进效应,可以带动就业量的增加。     

How does growth need strength influence employee outcomes? The roles of hope,leadership, and cultural value

Abstract

Strong growth need is essential if an employee is to be motivated to complete complex and challenging jobs. It is important for organizations to attract employees with high growth need strength and help them achieve positive outcomes. However, limited research has been conducted to examine the mechanism underlying growth need strength’s positive effect on employee outcomes. Based on hope theory, we hypothesized that hope mediates the effect of growth need strength on job performance and affective commitment by transforming employees’ general desire for personal growth into goal-related cognitive thinking, comprising both ‘will’ and ‘ways’. We further hypothesized the moderating effect of transformational leadership, and the joint moderating effect of transformational leadership and individual power distance on the relationship between growth need strength and hope. We tested our hypotheses with data from a sample of 265 subordinate–supervisor dyads from China. Data analysis results supported the mediating role of hope. We found that growth need strength has a stronger effect on hope when transformational leadership is higher, and this effect is the strongest when both transformational leadership and individual power distance are simultaneously higher. The implications of these findings for human resource management research and practice are discussed.     

资助参保型城市医疗救助模式研究

回顾了我国城市医疗救助制度的沿革,指出,资助参保模式是适宜我国的医疗救助模式,制度筹资能力不足是影响资助参保型城市医疗救助模式的主要瓶颈。应提高城市医疗救助制度的筹资能力,通过多个配套措施规避降低居民医疗服务可及性的风险,以达到保证医疗救助制度的救助效果。
