Measuring and improving the efficiency of the Chinese commercial banking system has recently attracted increasing interest. Few studies, however, have adopted the two-stage network DEA to explore this issue in the Chinese context. Because the entire operational process of the banking system could be divided into two sub-processes (deposit producing and profit earning), the evaluation of the sub-process efficiencies could be used to assist in identifying the sources of the inefficiency of the entire banking system. In this study, we utilize the network DEA approach to disaggregate, evaluate and test the efficiencies of 16 major Chinese commercial banks during the third round of the Chinese banking reform period (2003–2011) with the variable returns to scale setting and the consideration of undesirable/bad output. The main findings of this study are as follows: (i) the two-stage DEA model is more effective than the conventional black box DEA model in identifying the inefficiency of banking system, and the inefficiency of the Chinese banking system primarily results from the inefficiency of its deposit producing sub-process; (ii) the overall efficiency of the Chinese banking system improves over the study period because of the reform; (iii) the state-owned commercial banks (SOBs) appear to be more overall efficient than the joint-stock commercial banks (JSBs) only in the pre-reform period, and the efficiency difference between the SOBs and the JSBs is reduced over the post-reform period; (iv) the disposal of non-performing loans (NPLs) from the Chinese banking system in general explains its efficiency improvement, and the joint-equity reform of the SOBs specifically increases their efficiencies. 相似文献

Land subsidence risk assessment (LSRA) is a multi‐attribute decision analysis (MADA) problem and is often characterized by both quantitative and qualitative attributes with various types of uncertainty. Therefore, the problem needs to be modeled and analyzed using methods that can handle uncertainty. In this article, we propose an integrated assessment model based on the evidential reasoning (ER) algorithm and fuzzy set theory. The assessment model is structured as a hierarchical framework that regards land subsidence risk as a composite of two key factors: hazard and vulnerability. These factors can be described by a set of basic indicators defined by assessment grades with attributes for transforming both numerical data and subjective judgments into a belief structure. The factor‐level attributes of hazard and vulnerability are combined using the ER algorithm, which is based on the information from a belief structure calculated by the Dempster‐Shafer (D‐S) theory, and a distributed fuzzy belief structure calculated by fuzzy set theory. The results from the combined algorithms yield distributed assessment grade matrices. The application of the model to the Xixi‐Chengnan area, China, illustrates its usefulness and validity for LSRA. The model utilizes a combination of all types of evidence, including all assessment information—quantitative or qualitative, complete or incomplete, and precise or imprecise—to provide assessment grades that define risk assessment on the basis of hazard and vulnerability. The results will enable risk managers to apply different risk prevention measures and mitigation planning based on the calculated risk states. 相似文献

现如今礼品类高端产品由于自身的品牌效应,得到了市场上极高的受欢迎指数,因其包装精美和视觉鲜明的因素,越是在国际市场环境低迷的时候,越容易抢占市场。在中国的儿童玩具礼品领域,不单单需要效仿国际流行的设计趋势,而且还要积极提升国内自主品牌影响力,这才是中国当今发展儿童玩具礼品包装产业,缩小与国际水平之间的差距,夺回本土市场继而进军国际市场的必由之路。具体分别从消费群体和包装设计本身两方面进行调查和分析研究。 相似文献

传承传统重义轻利观念的大学教育,对学生的财富意识具有极大的压抑作用。改革开放以来,一部分人陷入拜金主义的泥潭,一部分人则保持着"饿死事小失节事大"的极端思想。调查的结果令人担忧,大学生财商整体水平较低。对大学生进行财商教育,是实现教育"使人更幸福地生活"目的之必然要求。 相似文献

《手批尔雅义疏》是近代著名语源学家黄侃从事语源研究实践最重要的成果之一,其批语中系联了大量的同族词。经过系统梳理,并运用同类互证方法等加以验证,可以发现,“荎:挃”、“殻:螯”、“睔:棆”、“憋:鷩”、“跳:狣”、“串:贯:毋”、“讹:化”等还没有被现当代学者证实的同族词确实存在同源关系。 相似文献

高校的泛行政化并不是当下才有的现象,而是古已有之。弄清高校的这种泛行政化现象的源头所在以及高校泛行政化的具体流变过程,需要对我国古代官学系统进行系统的分析,用图谱演绎的方法来对古代官学系统演进过程进行研究,是实现对高校泛行政化溯本求源的有效方法之一。 相似文献

本文将最小二乘支持向量机(LSSVM) 和二次推断函数法(QIF) 相结合,为个体内具有相关结构的固定效应部分线性变系数面板模型提供了一种新的快速估计方法;在一定的正则条件下,论证了参数估计量的渐近正态性和非参数估计量的收敛速度;采用Monte Carlo模拟考察了估计方法在有限样本下的表现并将估计技术应用于现实数据分析。该方法不仅保证了估计的有效性和统计推断力,而且程序运行速度得到较大幅度提升。 相似文献

A challenge for large‐scale environmental health investigations such as the National Children's Study (NCS), is characterizing exposures to multiple, co‐occurring chemical agents with varying spatiotemporal concentrations and consequences modulated by biochemical, physiological, behavioral, socioeconomic, and environmental factors. Such investigations can benefit from systematic retrieval, analysis, and integration of diverse extant information on both contaminant patterns and exposure‐relevant factors. This requires development, evaluation, and deployment of informatics methods that support flexible access and analysis of multiattribute data across multiple spatiotemporal scales. A new “Tiered Exposure Ranking” (TiER) framework, developed to support various aspects of risk‐relevant exposure characterization, is described here, with examples demonstrating its application to the NCS. TiER utilizes advances in informatics computational methods, extant database content and availability, and integrative environmental/exposure/biological modeling to support both “discovery‐driven” and “hypothesis‐driven” analyses. “Tier 1” applications focus on “exposomic” pattern recognition for extracting information from multidimensional data sets, whereas second and higher tier applications utilize mechanistic models to develop risk‐relevant exposure metrics for populations and individuals. In this article, “tier 1” applications of TiER explore identification of potentially causative associations among risk factors, for prioritizing further studies, by considering publicly available demographic/socioeconomic, behavioral, and environmental data in relation to two health endpoints (preterm birth and low birth weight). A “tier 2” application develops estimates of pollutant mixture inhalation exposure indices for NCS counties, formulated to support risk characterization for these endpoints. Applications of TiER demonstrate the feasibility of developing risk‐relevant exposure characterizations for pollutants using extant environmental and demographic/socioeconomic data. 相似文献
