Enterprise integration is a major global challenge of these times. It is now possible for a new generation of practitioners to engage this challenge selectively by applying a recently articulated version of systems science (WSS). This tutorial paper argues that a half-century of disarray of the systems field can be seen as ending; and that the distillation of WSS to support a wide variety of application areas (in this instance, enterprise integration) can occupy practitioners as they harness the work program of complexity (WPOC) selectively. Carrying out the WPOC yields predictable portfolio components, consisting of a well-defined mix of tangible and intangible products. The three causes of poor intellectual productivity identified by Kenneth Boulding are nullified when appropriate role matching is achieved between WSS and enterprise integration. 相似文献

Singapore’s remarkable success in economic development has been strongly associated with the country’s vigorous efforts to embrace the Information and Communication Technology (ICT) revolution to promote economic growth. This study provides a comprehensive investigation of the contributions of ICT to Singapore’s economic growth during the 1990–2008 period. It documents three key findings. First, there is a strong positive association between the intensity of ICT use and value-added and labor productivity growth at the sector level. Second, ICT investment contributed approximately 1 percentage point to Singapore’s GDP during 1990–2008, and its role in driving economic growth has become increasingly important over time. Third, the contribution of the ICT manufacturing sector to Singapore’s growth was notable, but it was on the decline and faced difficult restructuring challenges. This paper also provides valuable policy lessons and strategic insights for governments in both developed and developing countries that aspire to embrace ICT to promote economic growth. 相似文献

This paper attempts to shed the light on the nexus between firms’ productivity and economies of agglomeration in Egypt. Using a large dataset of firms in 342 firms’ four-digit activities in 27 regions (62,108 firms), we introduce three measures of agglomeration which are urbanization or firm diversification measured by the number of firms by governorate, localization and specialization measured by the average productivity by governorate and sector (generating externalities and knowledge spillovers) and finally competition measured by the number of firm operating in the same governorate and the same sector. We find strong evidence for the existence of agglomeration in Egypt after controlling for firm age, location, economic activity and legal status. In the Egyptian context, productivity spillovers gained from agglomeration measures outweighed the negative effects of competition implied by congestion. The latter is chiefly due to the lack of good infrastructure. When regressions are run by firm size, location and activity, our main findings show first that micro and small firms are more likely to benefit from localization and diversification compared to medium and large firms. Service firms benefit more from high level of diversification while manufacturing firms gain more benefits from knowledge spillovers and specialization in Egypt. 相似文献

Brazil is trying to identify ways to ally economic growth with climate change mitigation. Productivity gains in livestock have been pointed out as a promising alternative to achieve that goal. Thus, this paper analyses the economic impacts of a policy of productivity gains in the Brazilian livestock. Besides, we evaluate if the policy may conciliate agricultural growth and deforestation control, bearing in mind the reduction of greenhouse gas (GHG) emissions from land-use changes. The analysis was carried out through a computable general equilibrium (CGE) model, tailored to represent land-use changes, GHG emissions and removals. Besides, it made progress modeling the heterogeneity of climate, soils, and emissions in inter-regional models with many regions. The results show that productivity gains can effectively “save” land and thus avoid deforestation, especially in the Amazon and Cerrado (savannah) biomes. The policy also may boost the economic growth, spreading it to other regions of Brazil, like Centre-West and North, and increasing income and consumption in those places. However, as a climate policy, focused on the reduction of GHG emissions, the results may be counterproductive. The net amount issued may increase, as a result of the positive stimulus of the policy on the economy, and GHG emissions are directly related to the economic growth. 相似文献

Using data from the UK Census of Production, including foreign ownership data, and information from UK industry input-output tables, this paper examines whether the intensity of transactions linkages between foreign and domestic firms affects productivity growth in domestic manufacturing industries. The implications of the findings for policies promoting linkages between multinational and domestic firms in the UK economy are outlined. 相似文献

In this paper, I develop a regression-based system of labour productivity equations that account for capital-embodied technological change and I incorporate this system into IDLIFT, a structural, macroeconomic input-output model of the US economy. Builders of regression-based forecasting models have long had difficulty finding labour productivity equations that exhibit the "Solowian' property that movements in investment should cause accompanying movements in labour productivity. The production theory developed by Solow and others dictates that this causation is driven by the effect of traditional capital deepening as well as technological change embodied in capital. Lack of measurement of the latter has hampered the ability of researchers to estimate properly the productivity-investment relationship. Recent research by Wilson (2001) has alleviated this difficulty by estimating industry-level embodied technological change. In this paper, I utilize those estimates to construct capital stocks adjusted for technological change and then use these adjusted stocks to estimate Solow-type labour productivity equations. It is shown that replacing IDLIFT's former productivity equations, based on changes in output and time trends, with the new equations, results in a convergence between the dynamic behaviour of the model and that predicted by traditional (Solowian) production theory. 相似文献

This paper focuses on identifying the sources of productivity growth in ten Asian economies including China, Japan, the NIEs and the ASEAN-4. We calculate productivity growth and its components using distance-function-based Malmquist productivity indexes following Färe, Grosskopf, Norris, and Zhang (1994a). Hong Kong and Singapore are found to have the capabilities to shift the grand frontier of the APEC economies. But the productivity divergence might have occurred since the 70’s. The FDI contributes to the Asian growth either through catching-up or through technological innovations when a sufficient learning capacity is available in the host economy. 相似文献

基于时变参数的我国全要素生产率估计 总被引:3,自引:0,他引:3
本文应用时变参数状态空间模型,利用1953~2005年中国宏观经济数据,估计了样本区间内我国的全要素生产率(TFP),并与传统的索洛残差方法的计算结果进行了比较。分析表明:时变参数方法得到的TFP增长率计算结果由于不包含方程误差,比索洛残差方法的结果精确;TFP增长率的变化趋势,基本和GDP的增长趋势相同,只是有所滞后,滞后期一般为一年。 相似文献

This paper analyzes the international transmission and welfare implications of productivity gains and changes in market size when macroeconomic adjustment occurs both along the intensive margin of trade (changes in the relative price of existing varieties of tradable goods) and the extensive margin (creation and destruction of varieties). We draw a distinction between productivity gains that enhance manufacturing efficiency and gains that lower the cost of firms' entry and of product differentiation. Countries with lower manufacturing costs have higher GDP but supply their products at lower international prices. Instead, countries with lower entry costs supply a larger array of goods at improved terms of trade. Output growth driven by demographic expansions, as well as government spending, is associated with an improvement in international relative prices and firms' entry. While trade liberalization may result in a smaller array of goods available to consumers, efficiency gains from deeper economic integration benefit consumers via lower goods prices. The international transmission mechanism and the welfare spillovers vary under different asset market structures, depending on trade costs, the elasticity of labor supply, and consumers' taste for varieties. 相似文献
