Using replication research for just-in-time purchasing construct development

Using replication research, the validity of the just-in-time purchasing (JITP) construct is established. Although empirical researchers have examined JITP over the last two decades, a consistent set of valid, reliable factors has not been used. The lack of valid construct is a barrier to hypotheses testing and meta-analyses on JITP. This study confirmed the validity of six JITP factors: top management commitment, employee relations, training, supplier quality management, transportation, and quantities delivered using two different data sets and testing the first- and second-order structure of the JITP construct. Content validity, reliability, unidimensionality, convergent validity, discriminant validity, criterion-related validity, and an invariant factorial structure of the JITP construct were empirically established.

Linking performance drivers in production planning and inventory control to process choice

This study investigates how process choice relates to production planning and inventory control decisions. We empirically examine the validity of deductively derived patterns about these types of decisions. More importantly, we look for normative insights by exploring how production planning and inventory control decisions affect operations performance. Our findings show that production line and continuous flow plants use more of a level production strategy, and carry less raw material and work-in-process inventory. The performance drivers for these plants, through which the operations function excels, are effective utilization of equipment, reduced finished goods inventory, and reduced setup down time. To gain forward demand visibility and batching economies, job and batch shops rely much more on backlogs in their planning process. These plants use more of a production chase strategy and position inventory lower in the bills of materials. Four performance drivers for top-performing job and batch shops are to find ways that better anticipate customers' orders, have a more responsive chase strategy, carry less raw material or purchased inventory, and shorten production planning horizon, partly through less reliance on backlogs. It is intriguing that top-performing plants not only do the expected things, given their choice of process, but also excel in selected dimensions—some of which fit the profile normally associated with a different process choice. To monitor and continuously improve operations, evaluation ‘scorecards’ should pay particular attention to performance drivers, which change depending on the plant's process choice.     

中外管理者收购融资的比较与启示

国资委、财政部正式公布了《企业国有产权向管理层转让暂行规定》,对MBO的实施范围作了界定,对实施主体提出了规范化要求。文章比较研究了国内外MBO不同的融资模式,认为我国企业管理者收购受有关法律和金融制度的限制存在融资工具和融资机构单一,融资渠道和退出渠道不畅等问题,其潜在的法律和金融风险不可忽视。最后,笔者对改进我国管理者收购融资提出了新的政策建议。

中小企业研发困境的博弈分析

知识经济时代，企业自主研发是增强其竞争力的必经途径。而在国内，众多中小企业对研发投入持消极态度，尽管政府多方鼓励，但收效不大，且企业在自主研发的投入方面与发达国家有着较大的差距。可从严格保护研发成果、协作研发与加大政府的政策优惠力度等方面对中国中小企业的研发投入情况进行改进。

基于管理熵的接包绩效协同激励体系评价研究

本文以猪八戒网为研究对象,结合已往研究成果与猪八戒网调研结果,并将管理熵理论进一步应用于众包情境下,构建综合激励体系,从而测度激励体系协同激励效果。研究表明:目前猪八戒网接包绩效激励系统处于一定的有序状态,各激励指标的激励效果相对良好;二级体系内部指标协同效应较差,应注意"环境公平""品牌效应"与"信息转换机制"三项二级指标对激励系统稳定的干扰;"程序公平"和"交互公平"两项三级指标熵流值为正,对接包绩效产生显著抑制作用。通过测度激励系统的激励效果,有助于及时遏制正熵并提高激励负熵,进而实现总激励熵的下降,对激励盲点的发现与激励措施的动态维护具有重要意义。
