Death of linkages in host countries? A firm‐level study on the channels of productivity spillovers in the Malaysian manufacturing sector

Productivity spillovers from multinational corporations (MNCs) to local firms have been an area of keen research interest in developing economics. Claims of positive spillovers in the form of technology transfers have been questionable, in part because of the many ambiguous conclusions obtained. The paper argues that the lack of focus in the mechanisms underpinning spillovers may be one of the reasons for the ambiguity. Using local input–output linkages as the mechanism for technology transfer, this study examines the presence and the enabling conditions for spillovers. Accounting for the variations in firms' characteristics, the findings show that skills‐oriented MNCs participating in international production networks transmit horizontal spillovers to local establishments. Vertical spillovers from MNCs are mostly relevant only to lower‐skilled establishments. For skilled and export‐oriented local establishments, technologies learned from producing for international production networks are more significant than forming linkages with MNCs in the domestic market.     

浅谈电力系统污秽绝缘子闪络及其防制措施

随着现代化建设的不断发展,大气环境日趋恶化,空气污染导致电力系统的运行环境日益严峻,运行中的绝缘子表面沉积的各种污秽也越来越多。在满足一定的条件时,绝缘子会产生沿面闪络,这种由于绝缘子的绝缘水平下降而引起的闪络事故将给电网带来极大的危害,因此必须采取一定的措施加以防范,以保证电力系统的安全运行。     

解读新一轮改革的逻辑

"十八大"以后,中国进入新一轮改革时期。新一轮改革是一场问题导向式改革,新时期所出现的诸如经济增长乏力、效率低下、市场秩序混乱等新问题是新一轮改革的逻辑起点,放、激、管三管齐下是解决新问题的主要方式。新一轮改革的目标是处理好政府与市场的关系,而理顺政府与市场关系的关键在于充分发挥市场在资源配置中的决定性作用,通过市场发力形成中国经济增长的内生力,探索出一条具有中国特色的市场经济道路,这条道路就是中国模式。     

紧邻老旧民房的深孔松动控制爆破技术

为了保护融水至河池高速公路二分部项目K53桩号附近的老旧民房和村民祠堂,控制露天深孔台阶爆破开挖所产生的振动和飞石、滚石等有害效应对村庄的影响,通过采用露天深孔松动控制爆破的方法,利用数码电子雷管结合毫秒级延期起爆网络进行爆破参数的设计。严格控制单段最大起爆药量,预留靠近民房山体一侧做掩体,确定好延时时间间隔和抵抗线方向以及做好炮孔堵塞和炮孔覆盖等安全技术措施,从而减少爆破振动和飞石、滚石等有害效应。结果发现:爆破效果良好,无飞石和滚石发生,大块率较低,机械易于开挖。祠堂和民房地基采集到的振速数据远低于安全振动峰值。     

Total Factor Productivity and Energy Intensity: An Empirical Study of China’s Cement Industry

China is the largest cement producer and consumer in the world. The cement industry’s rapid growth has led to a large demand of energy. This study reviews China’s cement industry in terms of energy intensity and examines the effects of technological progress on energy intensity. It also discusses the feasibility of achieving China’s energy reduction targets. We employ the Granger causality test and find that the total factor productivity or technological progress causes the energy intensity of the cement industry. Impulse responses analysis also proves that in the long run the technological change contributes to the decline in energy intensity of cement production.

私人股权投资基金运作模式选择与对策研究

私人股权投资基金有契约型、公司型、合伙型三种组织运作模式，在法律的合规性、避免双重征税、投资管理的效率性、监督管理的有效性等诸多方面有较多差异。通过对三种股权投资基金的运作模式的分析，提出信托型私人股权投资运作模式在现阶段是理性决策。公司型私人股权投资运作模式适合早期阶段，有限合伙人股权运作模式是最终发展目标。     

Sustainability Strategy and Eco‐Innovation: A Moderation Model

This study develops a moderation model to examine the role of a proactive environmental strategy on eco‐innovation. Drawing upon the perspectives of contingency theory, this study argues that the impacts of sustainability strategy on eco‐innovation depend on market demand, innovation intensity and government subsidy. The sample used to test the hypotheses is obtained from the Community Innovation Survey in Taiwan. A total of 2955 manufacturing firms are included in the final sample. A logit moderating regression is adopted to analyze the models. The results reveal that market demand and government subsidy positively moderate the relationship between environmental strategy and eco‐innovation. Specifically, firms are more likely to adopt a proactive environmental strategy to improve eco‐innovation under high levels of market demand and government subsidy. Furthermore, the results indicate that innovation intensity affects the effect of environmental strategy on eco‐innovation, but the direction of the influence varies with different categories of eco‐innovation.

马克思货币需求理论与西方货币需求理论的比较

货币理论是经济学中最富争论的理论之一。货币理论的基础也就是供求规律。对于其中的货币需求理论,从古至今有不少学者发表了不同的看法,形成了几种互不相同但彼此又有一定联系的学说。比较这些理论的异同,对于我们学习货币理论并制定和分析现实的货币政策具有重要的理论意义和实践价值。
