Firm location,political geography and environmental information disclosure

As the subjective and objective factors that influence corporate behaviours, political region and firm location are of great importance to environmental information disclosure (EID). With spatial and political geography as a research perspective, this article makes a study by using the samples of manufacturing listed companies from 2009 to 2011. As a result, we determine that regulatory distance and political geography had negative effects on EID, while political geography weakens regulatory distance’s function. After considering an enterprise’s administrative rank, we determined that when the rank is higher, regulatory distance has negative effects on EID; when the rank is lower, the effects are the opposite. Regarding political geography, it always weakened the regulatory distance’s function. Moreover, the effects are significant only when the enterprises had low governmental regulation. The study shows the effects that firm location and political geography have made on EID. At the same time, this study also gives theoretical and empirical evidence to the necessity of raising governmental regulatory effectiveness.     

用于通信系统的干扰对消电路设计与实现

针对通信设备应用的复杂化和对在复杂电磁环境下工作的设备电磁兼容性提出的更高要求，通过分析对消技术的基本原理，提出了一种模拟电路和数字电路相结合的干扰对消技术，并研制出了基于该技术的干扰对消原理样机。对该样机的单机测试和系统联试结果表明，该对消技术具备点频干扰和噪声干扰的抑制能力，对消收敛时间小于100 ms，对消比大于43 dB，适合在窄带通信中应用并可推广到其他领域。该成果正逐步在实际工程中得到运用。     

Revisiting the labor supply effect of social security earnings test: New evidence from its elimination and reinstatement in Japan

We explore the labor supply effect of the social security earnings test in Japan on those aged 65–69 years through a combined examination of the elimination of the earnings test in 1985 and its reinstatement in 2002. We present evidence showing that the effects of changes in the earnings tests on the labor supply of the elderly are not symmetric, controlling for changes in the attributes of workers and firms. The repeal of the earnings test in 1985 did affect the earnings distribution of the elderly (especially for male), while its reinstatement in 2002 did not alter the earnings distribution.

低碳城镇化对就业的促进作用及保障体系构建

增强人的生存和发展能力,促进人的全面发展是以人为核心的中国新型城镇化建设的终极目标,实现这个目标的前提就是要保障和实现充分就业。低碳城镇化是新型城镇化的重要内容和必由之路,低碳城镇化对就业的保障应该更具公平性并且按照就近原则来推进。文章认为,在低碳城镇化建设过程中,要促进就业增长和提升就业质量,必须优化产业布局、产业结构与发展模式,扩大就业空间;建立健全劳动力教育培训制度,培养适应低碳产业发展需求的劳动者,提高劳动者就业竞争力;推进城乡劳动力市场一体化建设,提高人力资源利用效率,增强社会就业公平性。     

我国城市居民最低生活保障制度发展与完善研究——以长沙市为例

我国城市居民最低生活保障制度是我国实施比较成功的一项社会救助制度。目前，长沙的低保制度在制度设计和运行方面仍存在消极的救助取向、平均式的救助标准、配套政策的负激励效应以及管理监督体系不健全等一些问题。为此，有必要对其进行探索改革，通过采取积极的福利政策、制定科学的保障标准，推行分类施助和差异救助、建立健全低保制度的管理监督体系等积极措施解决其存在的问题，更好地发挥最低生活保障制度的有效功能。
