面向订单生产对企业资源规划的挑战

本文是一项由24位中国企业资源规划资深顾问参与的研究,主要研究目标是发现中国制造业中面向订单生产的管理趋势及其对ERP的挑战。本文首先提出了研究的8个研究步骤,由专家提出面向订单生产业务的管理趋势,并根据专家投票得到其中的10个主要趋势,接着研究了这些主要趋势的业务管理难度和ERP对其支持程度,最后分析了目前ERP支持面向订单生产业务的不足。研究结果表明,在面向订单生产环境下,企业需要更高的供应链管理水平,并且需要改进的生产计划与控制方法。研究结果还表明目前应用于制造业的ERP软件在支持面向订单生产的发展趋势方面表现出较多的不足之处,阻碍了管理目标的实现。     

农户采纳稻虾共作模式的邻里效应研究

[目的]稻虾共作生态农业模式在长江中下游地区发展迅速,对于这一生态农业模式的扩散机理研究,有助于推动其他生态农业模式发展。[方法]文章基于湖北省、湖南省和安徽省农户调研数据,采用二元Probit计量方法分析了农户采纳稻虾共作模式的邻里效应,并采用工具变量法对基准回归结果的内生性进行检验及计算出社会乘数效应。[结果]（1）农户的稻虾共作模式采纳行为存在显著的邻里效应,同村邻里农户采纳行为均值每提高一个单位,个体农户采纳稻虾共作模式的概率将提高26.5%;邻里农户采纳行为的社会乘数效应为1.69。（2）农户的稻虾共作模式采纳行为还存在显著的情景效应;加入合作社可以显著提高农户稻虾共作模式采纳行为。[结论]在生态农业模式采纳比较少的行政村内,可以采取适当的激励政策引导部分农户采纳生态农业模式,再通过邻里互动效应作用,间接影响其他农户,从而提高整体采纳水平,形成规模效应。优先采纳的农户通过技术示范、经济收益示范,影响和带动其他农户采纳;充分发挥合作社的辐射带动作用,促进农户生态农业模式采纳行为。

Has the introduction of S&P 500 ETF options led to improvements in price discovery of SPDRs?

This study sets out to investigate trading in Standard and Poor's Depository Receipt Trust Series I (SPDR) options and the impact on the price‐discovery process of SPDRs. The empirical results reveal a significant rise in liquidity within the SPDR market following the introduction of SPDR options. Furthermore, the results also show that the introduction of SPDR options has led to a significant improvement in the information share of SPDRs, and that the contribution of SPDRs to price discovery has become very close to that of E‐mini index futures. These findings imply that developments in the derivatives market can lead to improvements in market quality, including the level of liquidity and price discovery of the underlying securities. © 2011 Wiley Periodicals, Inc.

Reconceptualizing the spillover effects of foreign direct investment: A process-dependent approach

Theory suggests that FDI spillovers are a function of the level of foreign presence. We extend this view by developing and testing the premise that variations in spillover effects are the result of differences in the process of foreign entry. Drawing from the concept of time compression diseconomies, we develop the constructs of pace and irregularity of foreign entry, and demonstrate that they negatively moderate the relationship between the level of foreign presence and the productivity of host-country firms. We also explain how and why the moderating role of the process of foreign entry is influenced by the intensity of R&D and technical knowledge in domestic industries. We find evidence that firms operating in low-tech sectors are better able to absorb fast foreign entry.     

The determinants of board size and independence: Evidence from China

China's corporate governance reform offers an interesting context for investigating the determinants of board size and independence. Analysing a large panel dataset from 1999 to 2003, we find that Chinese board size is primarily driven by firm complexity; board independence is mainly driven by regulation. Some governance factors newly introduced in this study also have a significant impact. For example, board independence is negatively associated with the size of supervisory board and state ownership. The findings have important implications and provide new insights into the subject.     

Effects of store loyalty on shopping mall loyalty

The key purpose of this paper is to bridge a research gap in shopping mall literature by investigating the relationship between store loyalty and shopping mall loyalty. The paper also examines the effects of perceived store value and store relationship commitment on store loyalty en-route to loyalty towards the shopping mall hosting the stores. The study shows that store loyalty influences shopping mall loyalty under certain conditions and that such an influence is moderated by the geographic distance between the consumer and the shopping mall. Further, the study found that distance has a moderating effect on the relationship between perceived store value and store loyalty, but not on the association between relationship commitment and store loyalty. The insights provided by this study offer academics, retailers and shopping mall managers a richer understanding of the relationships between store loyalty and its antecedents, customers' distance from the mall, and shopping mall loyalty.     

专业化交易地理集中、区域市场一体化与浙中内陆城市圈层化——“义乌商圈”的空间效应分析

基于专业化交易地理集中促成的总合交易费用节约,义乌市场不仅衍生出周边产业集群,从而提升义乌城市集聚度,并进一步引致周边的浙中城市群走上圈层化的发展路径,构建起基于自主层级体系的城市共同体。本文借助新兴古典城市网络分层模型刻画了圈层化的微观机制,并启示内陆城市形成自主共同体,以获取类似海滨城市优势的途径。     

黄土丘陵沟壑区城乡协调发展研究

目的 受区域条件和城乡二元体制的制约,黄土丘陵沟壑区城乡发展滞后。新时期,亟待厘清区域城乡关系现状,为乡村振兴和区域协调发展战略的实施提供依据。方法 文章以黄土丘陵沟壑区57个区县为研究对象,分别构建县域城镇化和乡村发展水平评价指标体系,利用耦合协调模型探讨2000—2015年区域城乡发展的协调状况,结合相关分析探析“城”和“乡”对城乡协调发展的影响。结果 （1）区域城乡发展失衡,“城进村衰”问题加重。乡村人口系统、经济系统、社会系统和资源系统虽略有发展,但环境系统有一定程度衰退,而城镇化水平在各方面均取得较大发展。（2）区域城乡互动关系已趋稳定,城乡耦合模式以“中—中—高”、“中—低—高”为主。城乡发展协调水平总体较低,以勉强协调、初级协调为主。2000—2015年,区域城乡发展协调度空间差异明显缩小。（3）城镇化对区域城乡协调发展起主导作用,而乡村的作用较弱。结论 乡村发展滞后是制约区域城乡协调发展的主要原因,发挥乡村资源优势、加强乡村环境治理、激发乡村内生动力将有助于提高乡村发展水平、促进城乡协调发展。该研究有助于理解区域城乡关系现状,为区域协调发展和乡村振兴相关决策提供参考。
