海峡两岸证券业经营效率比较研究:基于Metafrontier方法 总被引:3,自引:0,他引:3
本文将Metafrontier思想与BCC-DEA模型相结合,综合应用Metafrontier DEA方法、Malmquist全要素生产率指数和Tobit模型,客观地评价具有不同生产技术的两岸证券商的经营效率。结果表明:台湾证券商发展水平趋同,大陆证券商良莠不齐,但竞争力逐渐提升;台湾证券商技术水平落后于大陆;大陆全要素生产率逐渐改善,台湾逐渐衰退;资产总额、负债比、地区生产总值是影响技术效率的关键因素,负债比、经济自由度、地区生产总值是影响技术落差的关键因素;金融危机对两岸证券业冲击显著。 相似文献

从产品技术含量的角度,采用SITC三位码数据,对比分析自2003-2012年以来中日韩制造业产品的贸易关系。研究结果表明:在世界市场上,中国制造业产品出口的整体技术含量虽然一直在提高,但是仍然低于日本和韩国,且出口结构也没有得到显著提高;在竞争互补关系上,中日和中韩两国间各类商品呈现出来的大部分都是互补关系,而日韩之间在几大类商品上则呈现出较强的竞争关系;在中国对日本与韩国的制造业产品出口方面,中国对韩国的出口结构优于对日本的出口结构,且中国对韩国出口的整体技术含量也要略高于对日本的整体技术含量。 相似文献

E. coli O157:H7 is an important source of foodborne disease. The E. coli pathogen occurs naturally within the rumen of livestock (including cattle) and does not affect the health of the cattle, however, can be a source of cross-contamination during food processing or environmental contamination of drinking and irrigation water supplies. A vaccine to reduce the risk of cattle shedding E. coli is licensed for use in Canada and the US, however, adoption of the vaccine by cattle producers has been extremely low. Using data from a survey of cow–calf producers in western Canada, the influence of a set of thirteen incentives to encourage adoption of the vaccine is examined using Best–Worst Scaling. Incentives include policy interventions, market/supply chain incentives, production protocol incentives, and producer reputation incentives. Heterogeneity in producer responses to the incentives is evident and is further explored with a Latent Class Cluster analysis. Results suggest that a ‘one size fits all’ policy to encourage adoption of an E. coli vaccine by cattle producers may be challenging. 相似文献

This paper identifies the importance of both creativity and environmental sustainability for developing individual learners and society as a whole. It suggests that sometimes these two concepts appear to be in tension and that, politically, each is often championed by different communities. The relationship between creativity and environmental sustainability is explored in three separate contexts: in a design and technology schools context where teenage learners are being facilitated to develop creative responses within design briefs that include environmental considerations; through interviewing student teachers who have undertaken an ecodesign project; and through interviews with professional ecodesign practitioners. The tensions, compromises and contradictions evident where there is limited experience of environmental issues is contrasted with the level of optimisation and creativity engaged when designers have more maturity in this area. Finally, some suggestions are made for taking forward creativity and environmental sustainability in technology education through an ecodesign capability approach.

The average cost of a sales call has declined approximately 15% over the past decade, while average salesperson compensation has doubled. These statistics illustrate an important benefit of technology: salespeople are more productive. To better understand the impact technology has played on sales and sales management, this paper examines the impact of sales technology from four perspectives: the salesperson, the field sales manager, the sales executive, and the customer. Noting that the needs and evaluations of technology vary, depending upon the functional position and viewpoint, a research agenda is offered that reflects these various perspectives. 相似文献

This study assesses the level of sophistication of livestock products in Africa by evaluating technology intensity and economic complexity of each product. Using trade data from 1995 to 2012, livestock commodity exports are classified based on technology intensity. Employing a method of reflection in computing the economic complexity of export products, we find that one fifth of African livestock commodity exports are manufactured with low technology while the rest is composed of raw materials. The results also show that the ten most complex livestock commodities represent about a third of African livestock total exports while the world level is almost double this figure. Yet African countries spend a huge share of their wealth on importing complex products. The results imply that by exporting non-complex products Africa loses nearly a third of the total value of its livestock exports. To boost the value of livestock products, African countries should exploit their untapped potential while securing the domestic market to achieve import substitution. This can be done by integrating with global value chains or developing niche markets at the regional or international markets and improving productive capabilities. 相似文献

This paper conceptualizes digital procurement readiness as a dyadic construct and introduces the supply chain practice view (SCPV) as a theoretical lens that can help guide future research on digital procurement. We build on a literature review and on dyadic, explanatory case studies to provide a nuanced understanding of how the digital readiness of supply chain partners—on both sides of the dyad—needs to co-evolve for the implementation of digital procurement practices. Specifically, we outline how the SCPV can serve as both a holistic and a supply chain-specific framework for future research on the following: 1) the antecedents that help explain why supply chain partners adopt inter-organizational digital procurement practices, and 2) the relational performance outcomes derived from their use. For managers, this study implies the need to explicitly consider interactions with and influences of supply chain partners in their quest to rapidly and effectively digitalize procurement. 相似文献
