能源碳排放与环境污染空间效应研究——基于能源强度与技术进步视角的空间杜宾计量模型

本文基于空间环境库兹涅茨曲线理论探讨经济发展约束下能源强度和技术进步对大气环境的空间效应作用机理，采用探索性空间分析工具、经典最小二乘估计（OLS）、空间滞后模型（SLM）、空间误差模型（SEM）和空间杜宾--可拓展随机性环境影响评估模型（Spatial Durbin-STIRPAT Models）探索能源碳排放与大气环境污染的空间格局和空间溢出效应。实证估计结果表明，能源碳排放与空气环境污染在空间分布上表现出空间正相关性和空间集聚效应；能源强度与技术进步对能源碳排放与大气环境的空间溢出效应显著。在此基础上提出了相应的政策建议。     

基于协整理论和前移回归模型的福建省耕地资源变动预测及其驱动机制研究

研究目的:探索改进时间序列预测法与多因素预测法在区域耕地资源变动预测及驱动机制分析方面局限性的途径。研究方法:(1)引入协整理论有关方法对时间序列数据平稳性及协整性进行分析和评估,为驱动机制研究提供思路;(2)探索构建具有"影响滞后"机制的前移回归模型预测方法。研究结果:在对福建省的实证分析案例中,上述方法运用效果较好,模型输出的预测数据及所作的驱动机制分析可为该省今后的种植业生产规划、农业土地规划与决策提供参考。研究结论:协整理论与前移回归方法的有机结合,可为区域耕地资源变动预测及驱动机制研究提供一种有效的工具。     

The Discouraging Effect of Risks in WTO Negotiations: Determinants and Perceived Changes

The observation has frequently been made that uncertainty about the legal meaning and the economic and political effects of WTO agreements exert a discouraging effect on the progress of multilateral trade negotiations. This article identifies the determinants of uncertainty and risk in the WTO. It also examines changes in these determinants over time, pointing to increasing levels of uncertainty and risk. The argument is based on a series of interviews conducted with members of national delegations to the WTO and with WTO employees.

Shutting up shop: understanding the international exit process in retailing

Internationalisation is a much-studied phenomenon. Exit from international markets has been less analysed. Where it has been studied, most work has been on motives and causes, with relatively little on processes. This article explores the process of international exit in a retail context. It examines the run-up to, announcement of and fall-out from the decision by Marks and Spencer (one of Britain's leading retailers) to close its French stores. The article concludes that understanding the process of market exit is at least as important both for theoretical and practical reasons as understanding the decision to exit or divest. Further research needs to be undertaken on market exit and the processes involved, in order to contribute further to the theory and practice of internationalisation.     

Investigating the influence of velocity performance on satisfaction with third party logistics service

The Third Party Logistics (3PL) service industry is characterized by customer relationships that can extend over several years, involving multiple instances of service delivery. When services are delivered on an ongoing basis, customers are able to not only evaluate positional (current) performance, but also velocity (rate at which the service changes) performance. This research presents findings from an empirical study utilizing an online survey of 3PL customers to examine the influence of these two types of performance on 3PL service satisfaction. Environmental moderators including market turbulence and competitive intensity are also examined, and results indicate that velocity performance is a more important driver of satisfaction when customers operate in industries characterized by high market turbulence. The findings suggest that 3PL service providers should implement velocity performance metrics, especially for customers operating in rapidly changing environments, and use velocity performance information during the sales process and customer negotiations.

城市边缘区空间重构的驱动机理研究述评

20世纪70年代以来,全球生产方式变革和资本积累体制变迁推动着我国快速城市化进程中社会经济体制转型和城市空间重构,城市边缘区作为城市空间增长的前沿阵地和社会异质性最强的地域类型,其驱动机理研究成为当前世界城市研究的热点。西方相关研究在结构-行为-社会行动者三个维度上不断实现理论整合,但考虑到我国独特的制度演化路径和社会经济结构,城市边缘区空间重构机理的构成和运作方式迥异于国外。国内当前研究成果偏重于宏观结构性驱动因素分析,而在相对微观的行为因素和关系因素研究方面还有待深入。因此,强化空间重构的行为过程和社会行动者关系研究,对于推动城市边缘区空间整合与社会融合,研拟空间重构调控策略具有非常重要的理论价值和现实意义。
