上市公司独立董事制度设计的合理性分析——基于二元制公司治理模式

文章通过对监事会和独立董事职能冲突以及现有各国公司治理结构的分析,推导出在二元制公司治理模式下实行独立董事制度的环境要求和独立董事职能不能充分发挥的原因,从而得出我国目前并不适宜引入独立董事制度的结论。同时,在现有立法仍然保留有独立董事制度的前提下,又提出了对独立董事和监事会制度的改革策略,以期实现两者相对协调地发挥其监管职能。     

区域分工合作背景下的旅游业发展战略分析——以黄山市参与泛长三角为例

黄山市是安徽省旅游业参与泛长三角区域分工合作的突破口。文章阐述了长三角区域旅游业发展现状及黄山市旅游业与长三角区域合作情况,分析了黄山市旅游业参与泛长三角区域分工合作的优势、劣势、机遇和挑战,提出了黄山市应采取创新旅游发展思路,整合旅游资源、调整旅游产品结构,提升旅游企业核心竞争力,延伸旅游产业链,完善旅游设施、优化旅游环境等战略对策更好地参与泛长三角区域分工合作。     

城市化进程与服务业、制造业发展的关系——一个新兴古典经济学的分析方法

尽管城市化与分工演进之间的正反馈作用已成共识,城市化对分工的作用并没有得到充分分析。新古典经济学由于采用消费者和厂商的二分法框架,限制了其对分工的分析,新兴古典经济学直接以专业化与分工为分析对象,是分析城市化与分工间复杂因果关系的有效方法。运用新兴古典分析方法,文章分析了服务业发展与城市化的关系,以及制造业产品创新和技术进步对城市化的影响。     

The legacy of state socialism on attitudes toward immigration

Does the politico–economic system affect preferences for immigration? In this study, I show that individuals exposed to life under state socialism have formed and persistently hold different attitudes toward immigration. By exploiting the division and reunification of Germany, I estimate the influence of state socialism on attitudes toward immigration. Drawing on rich individual panel data, I find that East Germans who lived under state socialism, are 15 percent more likely to oppose immigration than West Germans who spent their entire life in a democratic, capitalist country. This difference in attitudes toward immigration is persistent over time and across space, and largest for cohorts born and raised under state socialism. This gap in attitudes can be traced back to a longer-term deterioration in trust. Evidence from members of a group that opposed the authoritarian system highlights the importance of state socialist ideology for attitude formation.     

Individually rational rules for the division problem when the number of units to be allotted is endogenous

We study individually rational rules to be used to allot, among a group of agents, a perfectly divisible good that is freely available only in whole units. A rule is individually rational if, at each preference profile, each agent finds that her allotment is at least as good as any whole unit of the good. We study and characterize two individually rational and efficient families of rules, whenever agents' preferences are symmetric single-peaked on the set of possible allotments. Rules in the two families are in addition envy-free, but they differ on whether envy-freeness is considered on losses or on awards. Our main result states that (a) the family of constrained equal losses rules coincides with the class of all individually rational and efficient rules that satisfy justified envy-freeness on losses and (b) the family of constrained equal awards rules coincides with the class of all individually rational and efficient rules that satisfy envy-freeness on awards.     

Technological versus Pecuniary External Economies: The Former Should Rule the Roost

The paper endeavors to illustrate that though the existing literature emphasizes the dynamic role of Scitovskian pecuniary external economies to account for the growth of innovations, highlighting particular types of market interdependence, such interdependencies can just highlight quasi-rent-led static adjustments that do not ensure an endogenous growth of innovations; the possibility of the growth of innovations remains exogenous. In this context, the present paper highlights the importance of division of labor-led dynamic technological external economies that ensures the endogenous growth of innovations, underlining the need of reinterpretation of Allyn Young in a broader Kaldorian-Keynesian perspective. In this perspective, finance-led investment in more productive opportunities not only supports increases in market size but also begets further investment in (still) more productive opportunities. This understanding provides a more dynamic conceptualization of Keynesian pecuniary external economies that are driven by Youngian technological external economies.     

亚当·斯密农业发展思想研究

经济学之父亚当·斯密的传世名著《国富论》包含了非常丰富的经济发展思想,在《国富论》中,亚当·斯密重点对制造业、商业等城市经济进行阐述的同时,对农村、农业的发展也提出了自己的见解。虽然这些见解零散地分布在《国富论》的各篇章中,且距今已有二百余年,但是这些看似零碎的见解却包含着博大精深的农业发展思想,对现今我国的农村、农业发展仍然有着很强的指导和借鉴意义。     

大跨度天基数据链的TDD时隙调度分析与优化

针对天基数据链系统卫星间的传播时延较大且节点间距离变化较大等特点，提出了一种提高时频资源利用率、提升系统容量、减小时延的方法。在时分多址与空分多址相结合的接入方式下，进行了时隙调度的分析与优化，利用卫星星座的空间复用与大跨度传播时延特性，采用时隙编排、收发状态调整、帧格式优化等手段，将信道利用率和系统容量提升了1倍，将卫星节点在某一方向获得服务的平均等待时间缩短为原来的1/4，提高了天基数据链系统的服务质量。     

基于蚁群算法的路径规划问题研究

基于VRP问题及其解法,提出一种用蚁群算法解决邮车路径规划问题的新方法。该方法首先用网络图理论建立邮递路径收益损耗模型,在此基础上利用蚁群算法进行全局搜索得到全局导航路经,然后利用网络分区策略局部调节导航路经上的节点,得到更优路经。实例结果显示,利用该算法可以规划出一条全局优化路经,且收敛效率高。     

论税收立法权纵向划分的基本思路

目前我国税收立法权纵向划分存在着缺乏稳定的规则、行政性特征明显、税收立法权过度集中于中央、地方隐性税收立法严重等突出问题.我国税收立法权纵向划分改革的基本思路是:在宪政的基础上通过法律的方式建立适合我国国情的分税制公共财政体制;在此框架下结合分税制其他配套制度的完善将税收立法权总体上集中于中央;赋予地方必要的税收立法权,并对其进行制约与监督.
