国际政治视野中的环境安全研究综述

近年来,环境问题日益恶化,成为影响国家安全和人类社会可持续发展的重大问题,因而环境安全上升为国际政治领域的焦点问题。作为国际政治的新领域,学者们对环境安全的由来、性质、概念、特点及其国际政治效应的认识方面还存在诸多差异,辩明这种差异对于深刻把握环境安全对国际政治的影响具有重要意义。

Interest Organizations,Information, and Policy Innovation in the U.S. Congress1 2

Interest organizations are hypothesized to strongly affect public policy, but the evidence that they do so is mixed. This article argues that one reason for the disparity is a gap between theory and research: theory suggests that information provided by interest organizations should strongly influence elected officials, but there is no systematic research on its impact. We examine a potentially important source of information for members of the U.S. Congress—testimony at committee hearings—to ascertain if it affects the enactment of policy proposals. The data, based on content analysis of almost 1,000 testimonies on a stratified random sample of policy proposals, describe who testifies, their arguments, and the evidence they provide. Supporters of a proposal emphasize the importance of the problem being addressed, while opponents claim the proposed policy will be ineffective and try to reframe the debate. Information—particularly information regarding policy effectiveness—does affect the likelihood that a policy proposal will be enacted.     

试论我国旅游产业的区域性协作

关于区域旅游合作,目前相关的研究还存在一些误区。笔者认为,构建大旅游区是通过凸显区域旅游资源的共性特征来整合旅游资源和旅游活动区间布局的大手笔,并以此来整合旅游企业的生产链,促进和引导微观企业市场活动的"自组织性"。本文还对构建大旅游区的方法模式作了初步探讨。     

系统动力学及其应用研究中的几个问题

当前系统动力学及其应用研究的现状为:方法研究主要集中于理论和思想、方法和技术两大类;应用研究可归为组织规划及策略设计、社会公共管理决策、生物与医学、环境与资源等四大类。已有研究在心智模型的表达与完善、规范化策略设计、结构层策略设计、有效度测试、模型及策略的实用性等方面的研究还存在问题与不足,今后的研究可着眼于心智模式的相关研究、策略设计的规范化、与其他理论方法的互补、模型有效度研究及应用研究等。     

Global Trade Models and Economic Policy Analyses: Relevance,Risks and Repercussions for Africa

Computable general equilibrium models are widely used for trade policy analyses and recommendations. There is, however, increasing discomfort with the use of these models, especially in Africa. This article demonstrates that the results of several such studies of the impact of trade reforms in Africa differ drastically in terms of both magnitude and direction, failing to take account of key features of African economies. It also outlines potential consequences of the misuse of CGE models for policy evaluation and suggests pitfalls to be avoided.     

After the Paris Declaration: Taking on the Issue of Power

The new approach to assisting developing countries inspired by the Paris Declaration emphasises greater recipient control over the funds provided, thus confining donors’influence to upstream points in the policy process, where political aspects of development co‐operation become more important. Understanding better the role that power plays in the aid relationship will be critical to the implementation of the Declaration. This article shows how the political science literature can inform this set of issues. It argues that an understanding of aspects of power illuminates the challenges involved in transforming relations between donors and recipient governments as well as between governments and civil society organisations.     

农户模型方法在实证分析中的运用——以中国加入WTO后对农户的生产和消费行为影响分析为例

农户模型方法是从微观层次的角度把农户的生产行为和消费行为结合起来,来系统分析各种政策和外界冲击对微观农户的生产、消费、市场供给等行为的影响一个工具。本文从理论和实证的角度对农户模型方法进行介绍,并构建了一个用于分析中国加入WTO对农户生产和消费影响的局部均衡模型。这个模型系统把农户的生产和消费行为结合在一起,而且这个模型也不同于别的模拟模型,它是建立在微观模拟的基础上的。     

乡镇企业与农村城镇化“捆绑式”联动推进——中西部地区缩小差 …

目前我国中西部与东部的差距是多方面的，造成这些差距的原因也是多方面的。从中西部自身发展的角度看。在乡镇企业和农村城镇化的发展上的差距则具有十分关键的“连锁效应”。作为中西部地区的发展战略来说,加快乡镇企业和农村城镇化的发展对于支撑中西部的大开发，具有基础性作用，二者在高起点上实现“捆绑式”的联动发展，对于缩小中西部与东部地区的差距，具有关键性作用。     

我国森林群落建群种营养元素含量的区域特征

各地带性植被主要种营养元素含量的格局是热带和南亚热带森林优势种的磷含量低，有些植物出现富铝化特征，石灰岩山地上植物的钙含量高；暖温带和温带大多数植物磷含量相对较高，而钙含量较低，部分植物有聚铁和聚锰现象。
