基于环境绩效的长江经济带工业用水效率

使用2005—2014年长江经济带11个省(市)的面板数据,基于投入导向的超效率DEA-CCR模型,测算含有非合意产出的全要素工业水资源利用率,利用Malmquist指数对全要素工业水资源利用率进行分解,分析工业水资源利用率提高和降低的主要影响因素,对全要素工业水资源利用率进行收敛性分析,判断各地区工业水资源利用率差异的变化趋势。研究结果表明:不同省(市)工业水资源利用率差距明显,下游地区最高,中游地区最低;2005—2014年,长江经济带区域工业水资源利用率总体呈提高趋势;科技进步是推动全要素工业水资源利用率提高的主要因素;长江流域工业水资源利用率呈收敛趋势,省(市)工业水资源利用率差距在缩小。     

基于质量指数的经济增长转型测度研究——以深圳经济增长为例

中国经济如何实现由"速度型"向"质量型"转化是一个充满了探索性的问题,学者们从不同理论视角给予了广泛关注。而如何设计一个指数从定量角度测评速度向质量转化进程,以便直观地反映经济增长转型的度是理论研究不可或缺的部分。通过借鉴市场化指数的经济原理与设计思路,设计了质量指数作为测量经济增长模式转型的定量指标,定量测算了由"深圳速度"到"深圳质量"跨越的实现程度。实证测评结果显示:"深圳速度"已经开始向"深圳质量"转化,但人民生活水平提高的幅度与深圳经济发展水平存在较大的落差。以此为契机,为定量测度我国经济增长转型提供一个分析思路。     

建设工程施工成本控制观点探讨

The rate of seat belt use and its related factors among car drivers in Tehran,Iran after imposing new regulations

The incidence of road crash deaths is high in Iran. Seat belts can reduce the risk of death or serious injury. This study aimed to estimate the rate of seat belt use and its related factors for car drivers in Tehran, Iran after proclamation of the 2011 legislation. A roadside observational study was conducted in 2012 and 10,752 cars and taxis commuting in different streets of Tehran were screened in regard to drivers' seat belt wearing. Other variables including gender, age range, type of street, district, time of day and day of week were also collected. The rate of seat belt use was 70.9%, and was significantly higher in females, elders and on freeways and significantly less in afternoon hours, side streets and in taxi drivers. The rate of seat belt use in Tehran (a representative of Iran) is still low despite the implementation of new legislations. More initiatives are needed to increase this rate especially in certain groups and areas.     

Measuring Women's Quality of Life: A Discussion of Alternative Approaches

This paper reports our experiences with the application of a number of alternative approaches to a study of women's economic circumstances and quality of life in a typical western city. The important work of, especially, Martha Nussbaum on the capabilities approach to evaluations of “quality of life” has highlighted pitfalls associated with the use of a narrow informational base in studies of women's lives and has emphasized the value of qualitative methods in these evaluations. However, to date, most discussions of the relevance of plural approaches to studies of women's lives have been conducted in the context of developing countries. This paper contributes a practical, current example of the relevance of such approaches to assessments of the lives of women in western countries as well. The research findings reported in the paper also cast further light on the importance of several, related themes in the literature on the capabilities approach, namely the importance of understanding how women's aspirations and expectations change with their economic and social experiences; and the importance of appreciating the social uses of language and how this affects the way in which women describe their lives.

Stock Market Development and Long-Run Growth in Nigeria

Abstract

The study empirically assessed the relationship between stock market development and long-run economic growth in Nigeria for the period 1980 to 2000. The study used secondary data while four models of multiple regressions were specified. The regression results, which were obtained using the Ordinary Least Square (OLS), show that measures of stock market development statistically have no significant effect on economic growth in Nigeria during the period 1980 to 2000. The major implication of the findings is that if the Nigerian Stock Market is to significantly contribute to rapid economic growth, policies must be fashioned out to eliminate those factors that blur the effectiveness of the vehicle or transmission mechanism through which stock market activities influence economic growth.

Based on the findings, it was recommended that there should be an improvement in the attractiveness of the market as a major source of raising capital. This will entail improvement in the physical infrastructure, more efficient share transfer and delivering system and provision of adequate and timely information on the market. Also, there should be improvement in the institutional regulation, environment and legal framework such that a balance is maintained between the soundness and safety of the market. And finally, there is the need to internationalize the stock market to improve the flow of savings. This willgive the market the advantages of risk diversification, improve information flow and encourage corporate control through investment in equity.     

浙江需“中端崛起,高端突破”

浙江经济总量虽居全国第四,但是,浙江的产业经济主体,主要集中在传统制造业,而且是以中小企业为主体,而这种特征,决定了浙江的产业升级,长路漫漫。所谓,浙江未来的产业发展,首先是实现目前的中小企业的升级换代,从低附加值的产业,过渡到大众产业,从产业链的最低端,延伸到中端。
