省思与规制:我国跨境期货交易法律困境及应对

我国推进期货市场"走出去"及国际化战略须以跨境期货交易法律机制构建为前提。文章通过厘定跨境期货交易内涵边界及监管正当性,省思主要法律困境及应对思路,提出应致力于跨境期货交易立法监管理念创新,确立跨境交易监管认同机制,提升跨境期货衍生品交易经纪能力,适度扩大衍生品跨境投资参与主体范围,逐步取消QDII投资品种限制,并从跨境期货交易运行保障、立法监管、风险控制以及解纷机制等方面建构系统法律保护体系,切实保障跨境交易整体性金融安全。     

权力义务视角下完善向基层赋权的思考

2010年开始,向基层赋权作为行政体制改革的重要内容在全国范围铺开。从权力义务视角对其进行研究有现实的必要性。赋权的核心是行政权力的转移,以权力转移过程中涉及的诸要素为切入点,可以分析出多重权力关系和有关主体在其中的权力义务。在此基础上,通过保障行政相对人对于赋权的参与权、设计上级行政机关实施赋权的制度、消除上级行政机关赋权的依据问题和设计基层行政机关行使权力的制度等方式完善向基层赋权,既使行政机关能够有效推进行政体制改革,又能对行政权进行有效规范、保障行政相对人权利。     

秦迁陵县粮仓设置体系探讨--以出粮机构粮食来源问题为中心

除仓官外,秦迁陵县内的出粮机构还包括田官、离乡及司空等。它们并非都建有独立粮仓,所出粮食的来源也不尽一致。田官不设粮仓,它的出粮地是公共粮仓中的一间专属仓房。离乡建有供应该乡粮食开支的独立粮仓,且粮仓数量与该乡人口规模有关。小乡可能仅有一座粮仓,故有时会产生因储备不足而需要仓官额外输粮的问题。司空、发弩及■舍三者既未建有独立粮仓,也不如田官那般在公共粮仓内占有一间仓房,它们向外供应的粮食全都是由仓官转输。总之,秦迁陵县内设置的粮仓包括县级公共粮仓和离乡粮仓两类。田官、司空、发弩及舍虽承担了部分出粮职能,但并未给县内粮仓体系带来影响。     

Copper trade and production of copper,brass and bronze goods in the Oldenburg monarchy: copperworks and copper users in the eighteenth century

This paper explores trade connections – or the lack of such – between copperworks and copper processing plants in the Oldenburg Monarchy in the eighteenth century. Domestic customs areas, high tariffs on raw material export and import bans sought to encourage domestic copper and brass goods production of Norwegian copper raw material, however this was only realised halfway. The raw material from Norway was largely exported, and copper and brass materials used to produce copper-, brass and bronze goods were imported from all over the world. The copperworks and processing plants in the Monarchy never became strongly integrated due to several reasons. First, shareholders of copperworks acquired favourable credit deals abroad, and preferred to export the copper, and second, copper materials had different features and processing plants used all sorts of copper inputs in the making of goods, not only copper raw material. Norway produced mostly gar copper, so copper plants and coppersmiths had to turn elsewhere for other types of copper. Production of copper and brass goods increased, but did not meet the domestic demand partly due to a strong foreign competition. The optimal goal of ‘mercantilist theory’ regarding copper and brass import substitution was not reached.     

基于PSO的信息熵数据融合非均匀分簇路由算法

针对无线传感器网络分簇算法中能量分布不均衡导致的"热区"和簇头负载过重问题,提出了一种基于PSO算法优化簇头选举的非均匀分簇算法。在候选簇头选举和竞争半径计算过程中综合考虑节点动态能量、节点密度和节点距基站距离,将网络进行非均匀分簇,并引入PSO算法进行最终簇头选举。根据节点能量、节点密度和距基站距离确定簇间单跳多跳结合的路由规则,选取代价函数小的节点作为下一跳节点。基于节点信息熵确定融合阈值,进行簇内数据融合剔除冗余数据。仿真结果表明,改进算法的数据传输量比EEUC算法和UCRA算法分别提高了20%和10%,提升了数据的融合效率,有效延长了网络生命周期,簇头能量消耗得到均衡,减少了网络能量消耗,网络的整体性能显著优于其他对比算法。     

The financialization of the non‐financial corporation. A critique to the financial turn of accumulation hypothesis

One aspect in which non‐financial corporations (NFCs) are said to be financialized is that they have been increasingly engaged in financial accumulation from which they derive a growing proportion of financial income. This is what we call the financial turn of accumulation hypothesis. In this article, we show that the evidence used to sustain it, in the U.S. setting, has to be reconsidered. Our findings show that, contrary to the financial turn of accumulation hypothesis, financial income averages 2.5% of NFCs’ total income since the 1980s, oscillating since the beginnings of the 1990s until 2005 and then declining. In terms of assets, some of the alleged financial assets might actually reflect other activities in which NFCs have been increasingly engaged, such as tax avoidance, internationalization of production, activities refocusing and M&As.     

The economics of markets and platforms

Advances in the study of both markets and platforms contribute to economics. Platforms are typically digital markets, although platforms can designate markets generally. So, the economics of markets and the economics of platforms are one and the same. Platforms show the critical role of intermediaries in endogenous price adjustment and market clearing. The platform model remedies problems with general equilibrium analysis by combining and extending the basic Walrasian and Marshalian market models. The analysis of platforms provides explanations for the bid–ask spread, including market power, search costs, matching costs, adverse selection, and moral hazard. The study of platforms demonstrates the importance of participation and coordination in the formation of markets. The discussion emphasizes that platforms have significant implications for the theory of the firm. The analysis further considers how platforms affect innovation and entrepreneurship.     

沈阳城市周边耕地多功能评价

[目的]为探索城市化影响下城市周边耕地多功能的现状,分析其空间差异,为耕地保护及城市周边耕地发展提供参考。[方法]从耕地的生产、生态、社会和景观4个功能出发构建评价指标体系,利用熵权法确定指标权重,加权求和法计算单一功能和多功能值,并用ArcGIS进行空间分析,对沈阳城市周边50个乡镇(街道)的耕地多功能性进行综合评价。[结果](1)沈阳城市周边耕地的多功能性空间差异较为明显。生产功能远郊平原区最强,远郊山区和近郊区较弱;生态功能总体偏弱,个别乡镇较好;距离城市越远,社会功能越强;景观功能近郊区较强,远郊区较弱。(2)耕地的生态、社会和景观功能主要受距市中心距离的影响,生产功能受地形和距市中心距离的双重影响,而多功能则受地形、距市中心距离及各乡镇(街道)耕地主导功能等的综合影响。(3)沈阳城市周边的大多数耕地以农业生产为主导,景观文化功能整体相对较弱。近郊区耕地生态功能所占比重较大,但社会功能比重较小,远郊区则与之相反。[结论]沈阳城市周边耕地多功能性空间差异较为明显且不均衡,应科学规划城市周边耕地功能,优化空间布局,协调耕地各功能的关系,促进耕地多功能综合发展。     

Gender wage gaps and economic crisis in Greece

ABSTRACT

We examine gender wage gap (GWG) in Greece for 2013, by using a survey data set. Our findings show first, that the unadjusted GWG is 15.3%, while European Commission reports a value of 15%. Secondly, we derive the ‘adjusted’ GWG, using the Oaxaca and Ransom (OR) and the Juhn, Murphy and Pierce (JMP) methods to be ranging from 10% to 13.6%. Thirdly, looking into the behaviour of the full population, we find a decreasing trend for the discrimination effects, an increasing trend for the residuals effects and a ‘random’ endowments effects while moving to higher deciles. These three effects are associated to the economic crisis 2008–2015. Fourthly, our findings do not show evidence of either a ‘glass ceiling’ effect or a ‘sticky floor’ effect. Finally, that there is strong evidence that investing in higher education reduces the wage discrimination between sexes.
