国有企业高管薪酬管制与委托代理问题

由于国企高管的经营业绩难以被准确度量，加上监督约束机制不健全，高管的超额薪酬成为国企代理问题的一种典型表现，于是政府将高管薪酬管制作为应急措施来降低代理成本，缓解国企代理问题。采用双重差分法对2011—2018年A股上市公司的分析表明：第二次限薪令在有效限制国企高管薪酬水平的同时，没有对高管在职消费产生显著影响，有效降低了国企代理成本；但第二次限薪令也降低了薪酬激励效应，导致国企高管努力程度降低，由此造成的利益损失又成为新的代理成本。国企薪酬制度改革面临激励与管制的两难选择，应在国企分类改革的基础上对不同类型国企的高管采取不同的激励机制：对公益类及特殊行业的国企增强高管政治晋升激励，对竞争行业（营利性）国企则应在推向市场的同时放松薪酬管制，从而有效降低代理成本，解决国企代理问题。     

Does trade size restriction affect trading behavior? Evidence from Indian single stock futures market

Algorithmic traders use their advantage of speed to execute a large number of small-sized trades in a very short time. In the presence of a minimum trading unit (MTU) restriction, they are forced to trade at the smallest possible sizes, often restricted by the MTU. Using a novel data set of single stock futures market obtained from the National Stock Exchange of India, we show that the MTU restriction acts as a binding constraint for traders while optimizing trade sizes. Contrary to expectation, we find weak evidence that liquidity is positively impacted by the contract size revision.

跨区域旅游协作因素分析及其机制探讨——以桂西民族地区为例

本文在景区旅游竞争力构成因素研究的基础上,将区域间进行旅游协作相关性密切的要素分为旅游协作决定因素、旅游协作支持因素和旅游协作保障因素3部分,对其作了初步的内涵界定,并采用问卷调查方法对各旅游协作因素的重要性进行了排序.在此基础上,本文选定了桂西民族地区有一定代表性的20多个景区,通过实地考察和资料分析相结合,采取层次分析法对所选样本进行了较为详尽的分析、评定.初步得出了各景区的旅游协作总系数以及根据协作要素的不同层次分析而确定的协作类型,从而为各景区明确自身在区域协作中所处的地位和发展方向、相互间在协作过程中的空间布局及其调整等方面的基础性研究作了尝试性的探讨.     

Exit from the high street: an exploratory study of sustainable fashion consumption pioneers

In today's fashion system, dominated by business models predicated on continual consumption and globalized production systems that have major environmental and social impacts, the consumption of ‘sustainable fashion’ takes on an almost paradoxical quality. This paper explores this paradox by focusing on a previously under‐researched group of consumers – ‘sustainable fashion consumption pioneers’ who actively engage and shape their own discourse around the notion of sustainable fashion consumption. These pioneers actively create and communicate strategies for sustainable fashion behaviour that can overcome the nebulous and somewhat paradoxical reality that sustainable development in the fashion industry presents. Specifically, we use passive netnography and semi‐structured interviews to illuminate the role of motivational and contextual factors that help shape these consumers' definitions of sustainable fashion including such key behaviours as purchasing fewer garments of higher quality, exiting the retail market, purchasing only second‐hand fashion goods and sewing or upgrading their own clothing. Central to much of these behaviours is the notion that personal style, rather than fashion, can bridge the potential disconnect between sustainability and fashion while also facilitating a sense of well‐being not found in traditional fashion consumption. As such, our research suggests that for these consumers sustainability is as much about reducing measurable environmental or social impacts as it is about incorporating broader concepts through which to achieve goals beyond the pro‐environmental or ethical.

中国通货膨胀持续性的非对称特征研究--基于分位数自回归模型和分位数单位根的研究

基于1990－2013年中国月度CPI数据,本文通过运用分位数自回归模型和分位数单位根检验方法,研究了中国通货膨胀惯性的非对称特征,并分析了不同分位点上的通货膨胀惯性系数、单位根检验结果和半衰期。结果发现：中国的通货膨胀持续期存在明显的非对称特征,1998年之后通货膨胀持续性要显著低于1998年之前;相比于高通货膨胀水平,低通货膨胀水平上的通货膨胀持续性要显著降低。

煤矿土地复垦适宜性评价研究——以荣昌县曾家山煤矿为例

对土地进行适宜性评价是煤矿复垦工作的基础,为科学合理的复垦和利用土地提供了重要的依据。以重庆市荣昌县曾家山煤矿为例,结合矿区实际情况,通过对矿区的评价单元进行划分,确定相关影响因素,最终得出各地类的复垦方向,并对评价结果进行分析。结果表明,待复垦土地主要复垦方向为耕地和林地。     

我国油气资源税由从量计征改为从价计征的政策效应——基于双重差分法的计量分析

基于双重差分法,对西部地区油气资源税由从量计征改为从价计证的政策效果进行评估,以单位产值能耗、污染排放量和人均资源税收入作为政策效果变量,实证研究表明,油气从价税改革促使西部地区单位产出能耗相对于样本均值下降了7.90~8.55个百分点,污染排放量减少约1556吨,人均资源税收入相对于样本均值增加了2.74~3.03个百分点,通过采用不同处理方法进行稳健性检验后,以上结论仍然成立。
