<正> 随着改革开放的扩大和深入,我国以吸收利用外资为重点的三资企业发展迅速。到1992年一季度,共批准外商投资企业32000多家,吸收外资230亿美元,年递增率达30%以上。1992年,全国合资企业出口创汇可望达到100亿美元。三资企业不仅发展速度比较快,而且走势也在发生新的变化。总结分析外商投资走势,引导三资企业向高新层次递进,对于加大我国开放力度,促进外向型经济的良性发展,是十分必要的。 相似文献

目的探讨手术治疗根骨关节内骨折的临床疗效。方法本选取2009年12月~2011年12月我院收治的跟骨关节内骨折患者28例的临床资料。按其来院顺序,将其随即分为两组,切开复位内固定组(A组)和改良式复合外固定支架固定组(B组),每组患者均为14例。比较两组的临床疗效。结果 A组治疗在SandersⅡ型上,其优良率好于B组,且差异具有统计学意义(x2=8.45,P<0.05)。两组在SandersⅢ型-Ⅳ型的治疗上,B组好于A组,差异具有显著统计学意义(x2=14.36,P<0.01)。结论切开复位内固定和改良式复合外固定支架固定治疗根骨关节内骨折临床疗效均较好,且操作简单,并发症少,值得在临床中广泛应用。 相似文献

随着我国由计划经济体制向社会主义市场经济体制的过渡,仍然会有一定数量的国有医院要由国家直接控制经营。并需要相应的治理结构来规范其运行。本文的结果表明,在经济学理论上,公立医院的经营目的决定了产权改革既不是提高其经营绩效的充分条件,也不是必要条件。我们的理论分析否定了“产权优先”的改革观点,而为进一步完善公立医院治理结构的改革步骤提供了理论支持,并给出一定改革措施建议。另外,本文在理论上首次提出了非对称信息企业内部的“信息悖论”问题。这个广泛的结论不仅对于医院的改革是成立的,对于其他具有相同信息特征的企业都有理论意义。 相似文献

论东亚建立不确定性干预边界的汇率合作机制 总被引:1,自引:0,他引:1
论文首先分析东亚实施钉住混合货币篮的汇率目标区制存在的弊端,从新的视角提出,这一地区应建立以不确定性干预边界为核心的汇率合作机制;进而指出,这一汇率合作机制更具有弹性,可使各国规避货币冲击,易于搭建汇率合作的平台。 相似文献

Developing land use and transport PSS: Meaningful information through a dialogue between modelers and planners 总被引:1,自引:0,他引:1
One of the key barriers to integration of land use and transport planning is the lack of a “common language” (i.e. tools, instruments, indicators) that can support planners from both domains in developing shared visions and integrated strategies. Many of such tools and indicators have been developed in recent years, but not so many are implemented in practice. In this paper a new, participatory development approach for planning support systems (PSS) is proposed, termed “mediated planning support” (MPS) that addresses bottlenecks blocking this implementation. It is founded on insights from knowledge management, system dynamics and software innovation and is applied in the Greater Region of Amsterdam. This paper discusses the evolution of the PSS, highlighting the most useful elements which can be applied in other land use and transport planning projects. It offers insights for practitioners and researchers interested in land use and transport planning integration and for professionals that are dealing with supporting planning with information and technologies. 相似文献

We deal with the joint replenishment and delivery scheduling of the one-warehouse, n-retailer system in this paper. We suggest a more flexible policy for the joint replenishment and delivery scheduling of a warehouse compared with the existing researches. We introduce the mathematical model and two efficient algorithms for the joint replenishment and delivery scheduling of the warehouse. Subsequently, we develop the hybrid genetic algorithm (GA) and compare it with two efficient heuristic algorithms for extensive computational experiments. Further, we show the advantages of our GA in dealing easily with resource restrictions. 相似文献

External auditors regularly interact with various parties at work, such as their accounting firms, engagement team members, and clients. These interactions can help shape the nature of auditors’ social exchange relationships with these entities, which in turn may influence their behavior toward these targets. This installment of Accounting Matters draws from recently published research by Herda and colleagues to (1) explain how constructive auditor-target connections can develop and lead to beneficial outcomes like reduced auditor burnout and turnover intentions, as well as more citizenship behavior, and (2) discuss how these upshots might ultimately affect audit quality. This topic is important because audit quality translates into improved financial reporting, which helps stakeholders who rely on audited financial statements to make informed business decisions. Specifically, we underscore the key role auditors’ perceptions of fair treatment from a relationship partner play in fostering a strong psychological bond with the target via perceived support. We further consider how auditors’ consequent commitment to the target can result in favorable organizational outcomes, including enhanced audit and financial reporting quality. We also discuss practical implications for accounting firms. 相似文献

This paper identifies for the first time the optimal target markets employing the latent tourism demand expenditure, a novel concept in tourism literature. The study quantifies latent tourism demand between each pair of origin-destination through distinguishing by type of tourism and seasonality. It works with market shares that are estimated via a fractional regression model. Moreover, latent demand is clustered using a market segmentation approach based on a latent class regression. Finally, the optimal target markets are chosen depending on the expected latent tourism expenditure. The result has clear policy implications in terms of which markets are promoted, the optimal channels of communication and the maximum budget for each marketing campaign. 相似文献
