Bias is a much-debated issue in survey research. Answer effects (respondents claim to have behaved differently than they did in reality), nonresponse bias (nonrespondents differ on important variables from the respondents) and stimulus effects (by participating in a previous wave of a study, respondents change their behavior or attitude) can seriously distort the results of survey research. By using data from the 1998 Dutch National Election Study the authors show that the results of election research can indeed be affected by bias. Not only are significant effects found in the distribution of political attitude and voting behavior variables as a result of both nonresponse bias and stimulus effects, it is also shown that relations between variables change as a result of bias.  相似文献

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.  相似文献

ABSTRACT

The aim of this paper is to examine the relationship between external cooperation and entrepreneurial orientation (EO). This relationship is explored in cluster environment, wherein entrepreneurial organizations compete and cooperate simultaneously to pursue opportunities. The following hypothesis is tested: External cooperation is positively correlated with entrepreneurial orientation. The hypothesis is tested with a correlation analysis on a sample of 77 small-sized enterprises operating in the Malopolska region in Poland, wherein several clusters are active. Additionally, the regression analysis is conducted to examine the associations between inter-organizational cooperation and EO dimensions. The findings confirm that external cooperation is positively correlated with EO. This observation is confronted with a pro-competitive approach that is a constitutional element of the entrepreneurship concept. Moreover, the findings show that the correlation between external cooperation and a firm’s performance is stronger than between some other EO dimensions and performance. Additionally, the findings show the important role of relationships between organizations and their clients. In the paper, several remarks for development of the theory are discussed, including the need for incorporating inter-organizational cooperation into a set of entrepreneurial traits and reflecting it in entrepreneurial orientation scales. The findings confirm the importance of that direction of theory development that focuses on inter-organizational collaboration in the context of entrepreneurship.  相似文献

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.  相似文献

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。  相似文献

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。  相似文献

Inter-local cooperation is difficult to measure. In Poland, however, the data-set concerning financial transfers between local government budgets (one of the most popular quantitative measures of cooperation) has never been described in scientific literature. This paper aims at contributing to fill this gap. On the basis of the budget expenditures of all Polish local governments, we applied two research methods: OLS regression and Heckman two-stage regression. The results show that the decision whether to get into cooperation, and the decision on the extent of involvement are driven by different factors.  相似文献

东北三省和内蒙古东部组成的东北经济区,是我国最早形成并在结构上相对完整的大经济区,有着区域经济协作的天然条件和深厚基础。在振兴东北老工业基地的战略规划和实施中,要以区域经济一体化思想为指导,站在地区分工与协作的高度,分析和研究振兴东北老工业基地与内蒙古经济发展的相互关系,区域协作的阻滞性因素、协作的主体领域以及推进三省一区区域经济协作的总体措施,以实现要素区域间优化配置,从而加快振兴东北老工业基地的进程,使东北大经济区成为我国第四经济增长极。  相似文献
