产业的扩散与转移——基于专利的技术关联度实证分析

通过对产业间的技术关联测度,了解了产业间的技术扩散与转移情况,并进一步分析了可能的热点、方向及趋势。研究首先利用专利技术信息和共现方法,定量测度了十五个产业领域间的关联程度,然后分析相关的离散情况,最后结合时间维度探寻了可能的热点及新趋势等。研究中采用专利权人划分产业范围,并加入了权重的考量,确保了研究的客观、准确。结果表明,“半导体制造”和“电子”产业的影响范围相对较广泛;而“通信装备”、“计算机软件”、“互联网服务”、“半导体制造”和“汽车及零部件”产业近几年技术扩散较为活跃,特别是“汽车及零部件”产业预示着可能的重大变革。     

我国柑桔的国际竞争力分析

通过对市场占有率、显示性比较优势指数的分析,表明我国我国柑桔产品中除了宽皮柑桔外,其他柑桔产品在国际上几乎没有竞争力;我国的宽皮柑桔在1998年之前具有国际竞争力,但在1998年之后不具备国际竞争力;分析了我国柑桔产业缺乏国际竞争力的原因,提出了组建柑桔协会等中介组织、大力发展柑桔加工业等对策措施。

MULTIDIMENSIONAL DYNAMIC RISK MEASURE VIA CONDITIONAL g‐EXPECTATION

This paper deals with multidimensional dynamic risk measures induced by conditional g‐expectations. A notion of multidimensional g‐expectation is proposed to provide a multidimensional version of nonlinear expectations. By a technical result on explicit expressions for the comparison theorem, uniqueness theorem, and viability on a rectangle of solutions to multidimensional backward stochastic differential equations, some necessary and sufficient conditions are given for the constancy, monotonicity, positivity, and translatability properties of multidimensional conditional g‐expectations and multidimensional dynamic risk measures; we prove that a multidimensional dynamic g‐risk measure is nonincreasingly convex if and only if the generator g satisfies a quasi‐monotone increasingly convex condition. A general dual representation is given for the multidimensional dynamic convex g‐risk measure in which the penalty term is expressed more precisely. It is shown that model uncertainty leads to the convexity of risk measures. As to applications, we show how this multidimensional approach can be applied to measure the insolvency risk of a firm with interacting subsidiaries; optimal risk sharing for ‐tolerant g‐risk measures, and risk contribution for coherent g‐risk measures are investigated. Insurance g‐risk measure and other ways to induce g‐risk measures are also studied at the end of the paper.     

关于印度反倾销调查中“中国市场经济地位”

“非市场经济地位”是我国遭遇大量反倾销调查和反倾销败诉的主要原因。近年来，连发展中国家印度也频繁动用非市场经济地位武器对付中国。本文先分析了印度未给予我国市场经济地位待遇的情况及原因，论述了印度拒绝承认我国市场经济地位所带来的危害，并且从政府、企业和行业协会三个层面提出了如何争取印度承认我国市场经济地位的具体措施。     

PROPERTIES OF OPTION PRICES IN MODELS WITH JUMPS

We study convexity and monotonicity properties of option prices in a model with jumps using the fact that these prices satisfy certain parabolic integro–differential equations. Conditions are provided under which preservation of convexity holds, i.e., under which the value, calculated under a chosen martingale measure, of an option with a convex contract function is convex as a function of the underlying stock price. The preservation of convexity is then used to derive monotonicity properties of the option value with respect to the different parameters of the model, such as the volatility, the jump size, and the jump intensity.     

社会统筹养老金供给的两难困境与政策选择

在中国养老保险制度建立与完善过程中,其主要矛盾仍然是如何筹资和如何给付的问题。社会统筹主要通过提高缴费率和扩大覆盖面两条途径来增加基金供给,而现行制度却面临着养老金供给的两难困境。一是提高缴费率增加了基金收入,但不利于经济增长与扩大覆盖面;二是不同群体实行差别费率有利于扩大覆盖面,但加剧了养老金收支的失衡。经数理模型与实证分析,社会统筹缴费率应该保持适度水平,同时应该对不同群体实行差别费率的政策进行调整,以建立养老保障的长效机制。

Semantic Differential as an Assessment Tool of （Dis） Advantages of QMS in the Light of Accredited Certification in Poland

This article is a continuation of the issue in the field of assessment of （dis）advantages resulting from the implementation of the quality management systems （QMS） in a structure of the organization. The publication uses the results of studies conducted in the range of assessment＇s information completeness provided by the certification bodies （CBs） in the context of advantages and disadvantages of the QMS implementation in accordance with PN-EN ISO 9001. In addition, an attempt to define a tool for the QMS assessment of （dis）advantages in the organization has been made. The basis for empirical analysis of the issue was the information provided by an accredited management systems CBs recommended by the Polish Centre for Accreditation （PCA）. There are 33 units in Poland, which were granted by PCA with the accreditation within the range of ISO 9001：2008. In the first stage of the research work, a substantive analysis of websites content among mentioned CBs has been carried out. In addition, the paper proposes use of semantic differential method （SD） to evaluate （dis）advantages of the QMS. SD adaptation for the assessment of the QMS （dis）advantages is the authorial concept. The authors hope for polemic in this area. In the face of obtained results, an authorial SD construction has been proposed, which is useful and may help in the formulation and conveying of the relevant （reliable） information to potential clients in the range of （dis）advantages resulting from the QMS implementation to the organization. As a consequence, the recommendations have been set, which are kind of guidelines that could significantly influence the realignment of the information state conveyed on the internet by the CBs.
