水稻精简栽培模式对产量效益的影响

随着农村经济结构的调整,农村劳动力分配形式随之转变,从事农业生产的劳动力逐渐减少,水稻生产规模和生产方式出现了多样化,突出表现在水稻插秧方式的变革。对插秧效果、生育进程、抗逆性及产量效益进行调查分析,以便为今后推广应用提供理论和实践依据。     

1991-2008年中国物流业生产函数的实证分析

通过构造物流业生产函数,对物流业的投入与产出关系进行实证研究和量化分析,揭示1991-2008年间中国物流业的各投入要素对其产出的影响和贡献,据此将1991年以来物流发展分为三个阶段:初步发展阶段、快速稳定增长阶段和动荡增长阶段,并比较各阶段的产出增长模式。认为,中国物流业发展还没有实现规模经济效益,投入产出还存在不平衡;物流产业的振兴需要在未来继续提高物流信息化和标准化,引进和培养各个层次的物流专业人才。     

企业生产行为的优化方法分析

优化方法是经济学中常用的一种数学方法。在微观经济学中,企业的生产行为的目的是追求利润最大化,其生产法则是由优化方法得出的。这里分析了单一目标和多目标下的企业决策的优化方法。     

福建省生产与总产出的计量经济模型

本文论述建立一个能反映福建省生产和总产出经济活动关系的计量经济联立方程模型,对模型进行了历史模拟和事后预测,并进行产出结构分析.     

物流系统的数学模型

作为企业“第三利润源泉”的物流,对其成本的控制目前已经成为物流合理化进程中的热点问题。文章把物流系统看成是一个特殊的生产系统,用柯布一道格拉斯生产函数方程对其进行建模。把物流系统的产出——满足服务需求看成是此方程的产出,把运输费用、储存费用和管理费用看戍是投入．对物流系统的数学建模提供了一个新的方法。最后用这个物流系统模型对社会物流系统进行了实例验证。     

The ‘old’ and ‘new’ competition and Malaysian manufacturing firms: a case study

The majority of empirical studies dealing with production processes, work organization and industrial relations practices have been conducted in advanced industrial nations. This article reports on a study of the changing nature of work organization and industrial relations policies in the developing economy of Malaysia. It explores the broad patterns of change in human resource management, technology and work organization among Malaysian manufacturing firms in the context of Best's ‘old’ and ‘new’ competition. The question that arises is: does the evidence reveal that Malaysia is embracing elements of the ‘new competition’, or is it still locked into a regime of mass production, or both? The article argues that the ‘old’ and the ‘new’ competition should not be treated as a simple, straightforward duality model of development. The distinction between the two approaches is sometimes blurred and not so clear-cut. The case study observes that both systems could be operating side by side at the same time within an organization. Since the Malaysian manufacturing sector is expected to shift from simple assembly and process-type operations using labour-intensive techniques to the more advanced and higher value-added industries, greater investment in HRD to upgrade the skills of the work-force and the adoption of appropriate industrial relations policies that emphasize decentralization, greater employee involvement and continuous innovation will become crucial. To be able to compete successfully in the global economy would require a change in focus in the adoption of industrial relations and human resource development policies. For Malaysia to realize its aspiration to become an industrialized and developed nation by the year 2020 would require radical changes in those policies within the context of an integrated approach to economic and industrial planning.     

The spillover effects of biofuel policy on participation in the conservation reserve program

This paper studies the spillover effects of rising biofuel production on participation in the Conservation Reserve Program. Landowner participation decisions are modeled using a real options framework. We develop a land use decision model that captures biofuel-driven structural changes in market demand and derive threshold conditions that trigger participation in the program. We then quantify the impacts of biofuel production on participation at both the national and state levels using Monte Carlo simulations. The model is also used to analyze how changes in the persistence of the biofuel production boom and in the volatility of farming returns affect conservation participation decisions. Policy implications of the results are discussed.     

Innovation in work practices: a practice perspective

Dynamic capability theory argues that organizations' internal capabilities enable sustained competitive advantage. Innovations in work practices (commonly termed ‘high performance’, ‘high commitment’ or ‘high involvement’ practices) are an important source of these internal capabilities but research evidence shows low levels of penetration. Using a practice perspective, case study analysis of 7 establishments in the aerospace sector identifies three themes that are under-attended to in current research on innovations in work practices: industry and production context; distributed nature of management activity, and social embeddedness. Implications for future research are discussed.
