河北省金融业发展之对策分析

目前河北省金融业发展水平较低，要建设沿海经济社会发展强省，河北省必须首先成为一个金融强省。河北省金融业定位于围绕京津两个金融中心的区域性产业金融，即立足河北省区域，服务于“三农”、京津冀梯度转移产业、港口产业和海洋产业。应制定金融产业发展规划，采取优化金融生态环境，调整金融产业结构，整合金融资源，开放金融市场等措施来推动金融产业的发展。     

试论新公司法与公司的社会责任

公司必须承担社会责任是我国新公司法的要求,在实践中如何理解这一责任,甚为重要,直接关系到公司的发展和新公司法的实施.立足于现阶段的社会实践,公司社会责任的基本内涵是要求公司在其经营活动中不得有损于社会和谐及社会发展并因此而承担相应的社会义务,这一义务以保障劳工权益、保护环境、珍惜资源为核心.这种对公司社会责任的理解极具现实意义.同时,探讨如何将新公司法这一倡导性规范的要求合理地付诸实践也是我们不可回避的问题.     

试论传统文化与现代科学的同构兼容

探讨了传统文化与现代科学之间的同构兼容关系，认为在冲突中发展的人类文化是一个有机成长的开放系统，而科学的发展也是渐进积累和不断革命的统一，文化与科学的兼容特征决定了传统文化与现代科学完全可能谋求一种良性的同构兼容关系，

Comparing Environmental Policy Instruments in the Presence of Imperfect Compliance – A Case Study

In this paper, we aim to include rule making, implementation, monitoring and enforcement costs into the cost comparison of policy instruments. We use a simple partial equilibrium model and apply it to the textile industry. The model includes discrete abatement functions and costly monitoring and enforcement. The case study uses individual firm data to simulate the differences in abatement costs and compliance decisions between firms. We compare combinations of regulatory instruments (emission taxes, emission standards and technology standards) and enforcement instruments (criminal fines, civil fines and transaction offers). We show that the inclusion of information, monitoring and enforcement costs indeed alters the relative cost efficiency of the different instruments.     

区域发展中地理势能的初步研究

从区域发展的各个主要相关要素，初步探讨区域发展的地理势能。把地理区域作为一个系统，当一个区域相对于其它区域在地理位置、区际差异、区域结构和环境质量等方面，所显示出发展的综合优势即是该区域在这一系统中的地理势能。这种地理势能的大小受自然环境基础的深刻影响，并可随着不同的历史阶段、科学技术的发展而转化。一个地区的地理位置对比优势的态势为地理位置势能。地理位置和区位在自然条件上的势能促使其获得政策上的势能，并直接影响到产业结构的形成。地域间环境条件、生态功能、产业优势的潜在影响力为地理区际势能，如各种环境条件以及这些条件合理匹配的所谓地理地带性规律，决定了传统的农业生产。区际的差异还体现在区域发展的历史过程上，历史悠久的区域往往具有较高的地理区际势能。区域自然环境结构对于区域发展优势的影响力为区域结构势能。环境质量势能是环境质量对于区域发展优势的态势。生态环境脆弱、土地退化、自然灾害、环境污染等，大大减弱了区域环境质量势能。地理势能遵循能量守恒定律，势能转化的动力来源于自然与社会两方面。     

Domestic and international strategic interactions in environment policy formation

Summary. In this paper, we establish the most possilbe general formulation of the technology governing carbon-gas emission, giving rise to global external diseconomies, and ty to explore into the strategic interactions,both domestic and international, when an individual country decides on the environmental policies. Through the comparison among emission taxes, quotas, and standard in the perfectly competitive private economies, we find that the first two policies are equivalent but they are different in effects by virtue of what we may call the tax-exemption effect of emission standards. Such a difference in the policy effect further affects the other country's welfare through the global externalities, amplified through whether the government can precommit to either the emission tax or the emission standard.

Diversification, convex preferences and non-empty core in the Choquet expected utility model

Summary. We show, in the Choquet expected utility model, that preference for diversification, that is, convex preferences, is equivalent to a concave utility index and a convex capacity. We then introduce a weaker notion of diversification, namely “sure diversification.” We show that this implies that the core of the capacity is non-empty. The converse holds under concavity of the utility index, which is itself equivalent to the notion of comonotone diversification, that we introduce. In an Anscombe-Aumann setting, preference for diversification is equivalent to convexity of the capacity and preference for sure diversification is equivalent to non-empty core. In the expected utility model, all these notions of diversification are equivalent and are represented by the concavity of the utility index. Received: July 27, 1999; revised version: November 7, 2000
