基于实证分析的我国外贸依存度经济安全警示意义研究

文章在归纳关于对外贸易依存度研究的基础上,对当前的研究成果进行了分析,提出汇率,特别是实际汇率是影响我国进出口贸易依存度的一个影响因素。之后对实际汇率与贸易依存度的关系进行了理论分析和实证检验,发现理论分析与实证检验的结果截然相反。在对此结果进行分析后,提出了对外贸易依存度研究的重点及方向。     

新疆公立医院采购支出与付款内部控制研究

公立医院在采购支出与付款内部控制中存在着诸多问题。因此,加强医院自身的内部控制,建立公立医院采购支出与付款内部控制行之有效的监督制约机制十分必要。本文以若干家公立医院调查数据为依据,采用实证分析的方法对有关问题进行了分析,得出有关研究结论,并对公立医院如何进一步加强采购支出与付款内部控制提出了建议。     

高校特点对预算松弛影响的实证研究——以新疆为例

本文在文献综述的基础上,以新疆高校为例,对高校特点影响预算松弛问题进行了实证检验。研究提出5个需要检验的假设,根据有效问卷数据的统计分析,本文的研究结果发现：办学层次和预算松弛程度显著负相关,即办学层次越高,预算松弛程度越低;高校的预算松弛程度与学校规模正相关;相对于专业性院校,综合性院校预算松弛程度更高。     

企业主流与新流创新演进机理研究

激烈的市场竞争使人们意识到，企业既需要维持创新发展优势而抢占主流市场，又需要创造新的企业发展优势而赢取未来主流市场。着眼于这一关键任务，实现主流与新流创新演进成为企业持续发展的重点。因此，基于生物进化理论、企业进化理论和企业DNA理论，提出主流与新流创新演进经过了生成、变异、选择、协同阶段。深入研究主流与新流创新的生成、变异、选择、协同机理，并与企业创新发展实践相结合，为企业未来主流创新提供具体路径指导。     

互联网对企业协同创新中知识增值的影响——软创新资源的作用

互联网环境下协同创新中的知识增值运行机制发生重大改变。从知识流视角出发，整合资源基础观与知识基础观，在完善软创新资源概念的基础上，通过对4个案例的深入探索，分析软创新资源各维度对协同创新知识增值的影响。结果表明，互联网的群智性、泛在性等特点可以孕育出软创新资源，进而影响协同创新中的知识增值。其中，软创新资源包括开放型信息资源、协同型关系资源、创新型文化资源以及技术型能力资源4个维度，并分别作用于知识获取、知识转移、知识创造和应用，从而实现知识增值。最后，针对如何最大程度地发挥互联网在促进知识增值方面的作用，提出相关建议。     

离差交易的实证研究与探讨

离差策略是一种对冲交易策略，它是利用股指期权和一揽子股票期权（或部分成分股构成的ETF期权）之间的隐含相关系数，获悉市场成分股期权和股指期权波动率高低的相对关系，再在成分股期权和股指期权建立相反的头寸。离差交易策略选择暴露的风险因子就是隐含相关系数，离差交易使用的是对冲的平价跨式期权交易。选用2006年5月18日至2014年7月17日前复权的沪深300股指、上证50指数和上证180指数作为样本，进行实证检验。虽然结果显著性较强，但不排除存在模型不稳定性以及由于数据不充分造成对相关系数及波动率估计的偏误。同时，离差交易使用的是对冲的平价跨式期权交易，所以组合暴露较小的Delta风险。若离差交易涉及较大的资金量时，则需要用标的资产对组合进行动态Delta中性对冲。     

Project management infrastructure: The key to operational performance improvement

Process improvement programs such as Six Sigma, Lean, and Lean Sigma are very important and deserve serious academic research attention. However, definition problems make it difficult to study any specific type of process improvement program. Therefore, this study defines two organizational level program management factors, Strategic Project Selection (SPS) and Project Management Infrastructure (PMI), that are independent of any specific process improvement program. Drawing upon current literature, this study develops and tests theoretical models that relate SPS and PMI to operational performance improvement and to each other. Using empirical data collected from 53 supplier plants of one large high-tech firm, this study finds that at the plant level, SPS mediates the relationship between PMI and operational performance improvement. This insight contributes to both theory development and practice, suggesting that a viable strategy for a process improvement program’s success is to focus on PMI in order to enhance SPS and ultimately improve performance.

Conditional empirical likelihood estimation and inference for quantile regression models

This paper considers two empirical likelihood-based estimation, inference, and specification testing methods for quantile regression models. First, we apply the method of conditional empirical likelihood (CEL) by Kitamura et al. [2004. Empirical likelihood-based inference in conditional moment restriction models. Econometrica 72, 1667–1714] and Zhang and Gijbels [2003. Sieve empirical likelihood and extensions of the generalized least squares. Scandinavian Journal of Statistics 30, 1–24] to quantile regression models. Second, to avoid practical problems of the CEL method induced by the discontinuity in parameters of CEL, we propose a smoothed counterpart of CEL, called smoothed conditional empirical likelihood (SCEL). We derive asymptotic properties of the CEL and SCEL estimators, parameter hypothesis tests, and model specification tests. Important features are (i) the CEL and SCEL estimators are asymptotically efficient and do not require preliminary weight estimation; (ii) by inverting the CEL and SCEL ratio parameter hypothesis tests, asymptotically valid confidence intervals can be obtained without estimating the asymptotic variances of the estimators; and (iii) in contrast to CEL, the SCEL method can be implemented by some standard Newton-type optimization. Simulation results demonstrate that the SCEL method in particular compares favorably with existing alternatives.     

Strategic supply management,quality initiatives,and organizational performance

Researchers in supply chain management have found over the past two decades that supply management should be not merely a purchasing function but a strategic tool for supply chain integration. Supply management, the cornerstone of the integration of industrial supply chains, has evolved as a key research area. Based on quantitative and qualitative investigations of 225 electronics manufacturing firms, we examine the organizational impacts of strategic supply management (SSM) and the contexts of company size, process type, ISO 9000 certification, and quality management (QM) implementation that facilitate such an endeavor. We reveal that SSM is essentially a quality management initiative that requires bilateral efforts for continuous improvement and thus is not associated with the basic requirements of ISO 9000. We find that SSM improves on-time shipments, reduces operational costs, and leads to customer satisfaction and improved business performance. Developed based on contemporary premises in supply chain and QM, this research refines our understanding of the relationships among quality initiatives, SSM, and organizational performance.
