经济法与市场经济——对现代经济法的一种认识

经济法是现代市场经济发展到一定阶段出现政府干预失灵的特定历史下产生的法律部门和法律学科.它不仅是政府干预经济的有效手段,也是政府干预的约束和规范,是政府干预法治化和市场秩序优化的必然需求.同时,现代经济法法益保护也具有双重性既侧重于社会公共利益的保护,又兼顾市场经济个体私利的保护,实现社会公益和个体私益的最大协调和平衡.     

How can David orchestrate resources to enhance firm performance? A dynamic approach to coping with resource constraints

Given that the possession of abundant resources does not always guarantee superior firm performance, this study proposes a dynamic approach to enhancing firm value. Building on the resource orchestration thesis, we investigate how firms facing resource constraints enhance their capabilities over time by orchestrating resources and how this resource orchestration can play a role in improving firm performance. Using the dynamic perspective, this study identifies four resource orchestration modes, which are specified based on how a given firm dynamically allocates its resources to technology (enacted by R&D activities) and marketing (enacted by advertising activities). Accordingly, we claim that firms with resource constraints can enhance their performance by escalating or altering their resources over time. To test our hypotheses, we used a sample of 4078 small and medium-sized enterprises in manufacturing industries between 1984 and 2018. We found that focus escalation for technology positively affects firm performance, captured by Tobin's q, and that focus alternation toward either technology or market is positively related to firm performance. Finally, we discuss the theoretical and practical implications of our findings.     

用线性互补及二次规划理论分析市场均衡问题

本文讨论了一类完全竞争条件下的市场均衡问题,供给方的生产特征用线性规划模型进行刻划,市场需求函数源于一般经济意义下的模型,它是一系列相互独立的价格变量的函数．我们将此问题归结为线性互补问题,并依此讨论了均衡点的存在性．本文还讨论了一种用二次规划进行刻划的经济问题,并指出此二次规划的K－K－T条件等价于所讨论的线性互补问题．     

中国A、H股市场分割的根源分析

按照投资者的身份不同,中国的股票市场可分为A、B、H股三个市场,三个市场处于严重的分割状态,其最显著的表现就是A、B或A、H股双重上市公司股票的价差现象。本文拟以A、H双重上市股票为例,深入分析价差产生的原因,揭示中国股票市场分割产生的根源。     

Brexit: Be Careful What You Wish For?

In this paper, I focus on the British future from Brexit. The institutional form this will take is not yet fixed. However, one can consider likely outcomes based on dominant economic frameworks. From this perspective, it seems unlikely that Brexit will address the actual grievances that resulted in Brexit. These transcend European Union membership.     

社会服务供给集约化发展思路探索

针对我国目前社会服务供给主体发展现状和社会服务供给特性,结合市场集中度和集约化管理理论,分析我国社会服务供给主体存在的主要问题,论述社会服务供给市场集中度与社会服务供给集约化的关系,提出通过降低准入门槛、鼓励主体竞合、强化规模运营、培育大型主体、理顺主体关系、完善竞争机制及优化市场结构等策略与措施,来推动社会服务供给集约化管理。     

Bayesian Design of Special Type of Double Sampling Plans for Compliance Testing

Bayesian acceptance sampling plans, which utilize prior information on the process variation, can be employed as an alternative to conventional types of plans for taking decisions on the disposition of submitted lots. A special type of double sampling inspection plans by attributes with small acceptance numbers using Bayesian methodology is presented in this paper emphasizing its significance over small acceptance number single sampling plans. The procedures for designing such sampling plans for specified degree of discrimination which would ensure protection to the producer and consumer are discussed with illustrations under the conditions for the application of gamma-Poisson distribution.     

Open spaces for dialogue promoting mental health as a social work education methodology

ABSTRACT

The authors discuss service user involvement as a key approach regarding training of social workers. In many European Union countries this is a stable practice with a lengthy tradition in research and application. However, in Poland it is almost entirely absent and marginalized. This article presents the results of a participatory action research project conducted at the Institute of Sociology of the Jagiellonian University in Krakow, the objective of which was to identify and critically analyze the key substantive and formal aspects of training of social workers with the participation of individuals with experience of mental illness. This research project adopted an open approach to cognizing reality based on qualitative co-participatory methods. In the conclusion, the authors emphasize that the fundamental criterion for the success of this particular form of training is voluntary and differentiated participation of students—both in the role of people sharing their own experience and as learners—as well as shaping a culture of open dialogue, educational alliances of recognition and recovery, the foundation of which is axiological experience.     

西班牙—摩洛哥边境的建构与治理研究

休达与梅利利亚地处非洲北端地中海南岸,是孤立在非洲大陆上的两个西班牙飞地。这两座城市的陆上边界活动与经济要素的流动,反映出摩洛哥与西班牙、欧盟与非欧盟国家之间的冲突与交流。其建构与治理不仅影响着两国的政治稳定、经济发展、外交关系,也影响着欧盟的移民政策和欧洲—非洲关系,同时建构了独特且动态的边民认同。2020年受到新冠肺炎疫情的影响,休达与梅利利亚的边境空间有了新的变化。本文通过梳理该边境问题的产生与流变,分析其“双重性”“交织性”“波动性”等特点,进而指出,休达与梅利利亚的边境空间具有屏障功能、桥梁作用、认同建构、边境建构及其重构等作用,其对研究飞地边民认同、欧盟政策与欧洲—地中海关系意义重大。
