检视都市永续发展指针的发展历程与内涵:从指针系统建构到政策评估

本文回顾国际上相关的都市永续发展指针系统,探讨指针系统架构与内涵之间的差异,进而说明永续台湾评量系统中"都市台湾"指针系统的重要特色,以及指针项目选定的理论基础.藉由永续台湾评量系统中22个范畴的型态辨识,本文分析了都市在台湾永续发展中所扮演的角色,确认都市生产与生活型态对于整体永续发展的重要性,也验证了生态系统观点中都市对于环境的依存与影响.考量都市发展决策过程需要永续性的评量机制,本文利用都市永续发展指针作为政策评估的重要变量,应用交互式计算机软件<感受性系统模型(Sensitivitv Model Tools)>以系统性观点进行都市发展政策永续性的评析.透过系统软件功能掌握变量结构的完整性以及系统变量之间的相互影响关系,并藉助于团体咨询与讨论的沟通方式建构半量化的(semi-quantitative)系统变量,配合概念化及模糊化的方式界定变量水准以及函数关系进行系统仿真工作.籍由系统仿真了解变量之间的互动关系,而政策评估案例分析显示台北市硬件建设政策较空间调整政策发挥较大的效果.永续指针与系统工具的结合整体而言提供了都市政策永续性评估的沟通与预测接口.     

A Dependence-Trust Modelm of Export Alliance Performance in Small and Medium Enterprises (SMEs)

Abstract

This paper focuses on the export performance of US environmental technology (EnviroTech) firms, which are predominantly small and medium enterprises (SMEs). We conceptualize and empirically test a model of perceived export performance contingent upon the perceived effectiveness of host country partner (HCP) alliances, dependence, and trust in the HCP. We find that US SME EnviroTech firms contemplating exports need two critical ingredients for success. First, they must forge close, cooperative, long-term strategic alliances with HCPs for mutual benefit. And second, they must pay specific attention to building trust in the HCP in order to achieve greater success with the strategic alliance and exports. Though dependence on a host country partner increases the vulnerability of the exporter and detracts from an effective alliance, trust is the antidote that can neutralize the negative impact of dependence.     

Case Studies of Technological Change and Organisational Culture

Abstract

This paper focuses on technology as a central force in shaping cultural and environmental conditions as well as their interrelationships within an organisation. The research was carried out in Systems India Ltd., a subsidiary of Systems Corporation of USA, which is one of the oldest multinational corporations in the world. The two case studies from Systems India Ltd. bring out the ‘role of strategy in technological changes’ and the ‘role of leadership in technological changes.’ The findings of these two case studies when compared with three partner companies in similar industry indicated similar relationship between culture and technological change and organisational culture in Systems India Ltd.     

An exploratory review of the relationship between enterprise training and technology upgrading: evidence from South African manufacturing firms

The study examines the extent to which disaggregated training variables are related to technological upgrading, in the context of a middle-income developing country trying to manage its integration into the global economy. For a developing country, successful integration into the global economy requires that local manufacturing firms are able to competitively restructure, as a precondition for survival and long-term growth. Consequently, skills and technological upgrading are crucial in raising the international competitive advantage of local firms. Enterprise-provided training is one means that can be used by local firms to continuously upgrade their knowledge bases, increase their international competitiveness, and enhance employment growth over time. This paper uses South Africa as a case study, to demonstrate how economic reform measures can expose skills deficiencies in the manufacturing sector and lead to an increase in capital intensity of the sector. Exposure of skills deficiencies, in turn, raises the importance of skill-upgrading through schooling and training of existing workforce. Despite a couple of studies on the evolution of the labour market in South Africa, no previous research has explicitly examined the relationship between technological upgrading and disaggregated training/learning variables at the firm level. This paper aims to fill that gap by focusing on disaggregated enterprise-based training efforts. The study uses the Human Capital theoretical framework to answer the main research question: Which disaggregated learning variables (i.e., on-the-job or off-the-job training offered to different occupational groups) are significantly associated with technological upgrading? The study raises possible issues of heterogeneity in returns to training offered to different occupational groups in the context of technological-upgrading. On the other hand, technological upgrading may not necessarily always disadvantage all unskilled workers. Possible policy implications of research findings are outlined.
