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.     

Effects of cross-border capital flows on stock returns of dual-listed firms in mainland China and Hong Kong: Evidence from a natural experiment

This study analyses the effects of the Shanghai–Hong Kong Stock Market Connect policy on the price disparity between A-shares and H-shares of dual-listed companies (DLC). Using a difference-in-difference estimation method, we show that the policy decreases the relative twin cumulative abnormal returns of treated DLC by 3% and narrows the price gaps between A-shares and H-shares. We determine that the rising demand for H-shares, which are newly accessible by mainland investors, drives the price of H-shares up. By contrast, the price of A-shares remains unchanged. Further analysis reveals that cross-border capital flow is the main force of the policy.     

单车场无时间窗甩挂运输车辆调度的启发式算法

考虑了牵引车空驶、带空挂车行驶和带重挂车行驶所引起的成本差异，定义了牵引车运行成本的概念，将总运行成本最小作为调度方案优劣的判别指标，并同时考虑牵引车数量最少。将牵引任务分为四种类型，定义了任务链、虚拟任务、链内交叉和链间交叉的概念，提出了一种求解该类单车场甩挂运输车辆调度无时间窗约束的启发式算法，包括初始调运方案、链内优化、空车调运交叉、牵引车数量优化和链间交叉。最后给出了仿真算例，算法优化后的最终方案与初始方案相比，牵引车数量减少，总运行成本降低，验证了算法的有效性和可行性。     

高大平房仓储粮减损增效探索

高大平房仓储粮第一年秋、冬低温季节利用小功率风机进行下行式机械通风降低基础粮温;储存稳定期在确保储存安全的前提下,进入第2年、第3年秋冬季节则采用自然通风;气温上升季节对仓房实施隔热密闭、仓顶喷淋等一系列控温措施,在低能耗的情况下,可有效控制粮温,且大大减少了因通风产生水分散失而造成的储粮损耗.经过3年的储藏,损耗率低至1.42‰,且稻谷品质达到要求,降低储粮保管费用.     

Is time-variant information stickiness state-dependent?

This paper estimates information stickiness with regard to inflation expectations in the United States and the Eurozone for the 1981/06–2015/12 and 1998/Q4–2015/Q2 periods, respectively, and further investigates whether such information stickiness is state-dependent. Based on a bootstrap sub-sample rolling-window estimation, we find that information stickiness varies over time, which contradicts the strict time dependency implied under sticky-information theory. We provide evidence that information stickiness depends on inflation volatility, which indicates that information stickiness is state-dependent and that it has a time trend. Using a threshold model, we estimate structural changes in the state-dependence and time-trend of information stickiness. The results show that information stickiness has been more dependent on inflation volatility and has had a higher time-trend in both regions following the 2008 financial crisis.     

全球城市的经济地位研究

全球城市成为认识全球经济的一个视角,越来越多的研究聚焦全球城市,这既反映了世界经济的新变化,也反映了城市发展的新变化。经济全球化的"分离"和"集聚"打造了全球城市。信息技术成为全球城市的技术基础。全球城市网络成为全球城市的外部条件。全球公司占据全球城市的关键地位。全球城市的意义在于服务于全球经济,其服务的属性是生产性服务,主要形式是商务服务和金融服务。全球城市驱动全球经济,全球城市集聚一国的经济能量,全球城市应该成为中国经济的一个方向。全球城市已经成为北京上海的发展目标。     

农业创业情境下商业模式设计的影响机制研究——基于模糊集定性比较分析

农业创业者如何通过整合与管理资源与能力，设计新颖型商业模式创造更多价值，是实现乡村振兴战略的关键措施。文章基于资源编排、商业模式理论，以央视《致富经》栏目40个案例为样本，运用模糊集定性比较分析（fsQCA）方法，剖析资源编排、机会能力、创业学习所构成的前因变量组态对农业创业活动中商业模式设计的影响机制。研究发现，资源编排在农业创业活动中发挥不可或缺的关键作用；相较于资源结构化和资源捆绑，资源利用在新颖型商业模式设计中的作用更为突出；机会能力须与资源编排共同作用，方可实现新颖型商业模式设计；在资源编排作用缺乏时，创业学习的发挥有助于新颖型商业模式设计的形成。研究成果诠释了农业创业情境下资源编排、机会能力与创业学习对商业模式设计的影响机制，为开展农业创业活动提供指导。
