改革开放以来,中国的M<,2>/GDP不断攀升,这种现象已成为中国金融之谜.本文试图从融资结构的角度去解释中国偏高的M<,2>/GDP比值,通过考察M<,2>/GDP的备组成部分,认为银行主导型的融资结构是导致中国高M2/GDP比率的主要因素,进而分析该融资结构下带来的巨额商业银行不良资产对M<,2>/GDP变动的影响. 相似文献

随着计算机技术在电视领域中的不断应用,非线性编辑已成为电视台节目后期制作的主流方式,非编网作为电视台的核心之一,其可靠运行的重要性不言而喻。而非编网能不能安全高效运行,在相当程度上依赖于我们是不是结合实际、科学合理地对其进行管理维护。下面结合我的工作以河南电视台非编网为例,谈谈非编网的管理维护。 相似文献

为使城市生活污泥得以无害化、资源化综合利用,以过50目城市污泥作为载体、钛酸四正丁酯为钛源,采用溶胶-凝胶法制备城市污泥-二氧化钛复合材料,并就其对甲基橙的光降解催化作用进行了研究。实验结果表明,污泥与钛酸四正丁酯质量比为1:5所制备的城市污泥-二氧化钛复合材料经过500℃煅烧1小时后,对甲基橙具有较好的光催化降解作用,可在印染废水中推广使用。 相似文献

The debate regarding rising temperatures and CO2 emissions has attracted the attention of economists employing recent econometric techniques. This article extends the previous literature using a dataset that covers 800?000 years, as well as a shorter dataset, and examines the interaction between temperature and CO2 emissions. Unit root tests reveal a difference between the two datasets. For the long dataset, all tests support the view that both temperature and CO2 are stationary around a constant. For the short dataset, temperature exhibits trend-stationary behaviour, while CO2 contains a unit root. This result is robust to nonlinear trends or trend breaks. Modelling the long dataset reveals that while contemporaneous CO2 appears positive and significant in the temperature equation, including lags results in a joint effect that is near zero. This result is confirmed using a different lag structure and Vector Autoregressive (VAR) model. A Generalized Method of Moments (GMM) approach to account for endogeneity suggests an insignificant relationship. In sum, the key result from our analysis is that CO2 has, at best, a weak relationship with temperature, while there is no evidence of trending when using a sufficiently long dataset. Thus, as a secondary result we highlight the danger of using a small sample in this context. 相似文献

This paper explores the ability of some popular income distributions to model observed skewness and kurtosis. We present the generalized beta type 1 (GB1) and type 2 (GB2) distributions' skewness–kurtosis spaces and clarify and expand on previously known results on other distributions' skewness–kurtosis spaces. Data from the Luxembourg Income Study are used to estimate sample moments and explore the ability of the generalized gamma, Dagum, Singh–Maddala, beta of the first kind, beta of the second kind, GB1, and GB2 distributions to accommodate the skewness and kurtosis values. The GB2 has the flexibility to accurately describe the observed skewness and kurtosis. 相似文献

ABSTRACTThis research advances understanding of mobile device use in a leisure context by applying and expanding the Unified Theory of the Acceptance and Use of Technology 2 (UTAUT2) to festival settings. Through on-site surveys at three festivals the UTAUT2 model and an adapted version for mobile device use at a festival were examined using confirmatory factor analysis and structural equation modelling. Results reveal that the modified UTAUT2 demonstrates good fit, and the main factors affecting device use at festivals are performance expectancy, hedonic motivation, habit and age. The findings suggest that the festival context plays an important role in understanding use and should be included in future research. By knowing factors that affect use, practitioners can design experiences where technology enhances the festival and does not interfere with attendees’ experiences. 相似文献

Abstract. The paper investigates how monetary policy shocks influence the composition of firms' external finance given that firms are heterogeneous. Heterogeneity stems from differences in the availability of internal funds and in the monitoring costs associated with bank finance. These costs are determined by the intensity of the lending relationship. By using a delegated monitoring approach it is found that bank loans serve as a substitute for internal funds if the lending relationship is sufficiently close. Moreover, banks with strong credit ties to their customers are not only able to protect borrowers from liquidity constraints following a monetary tightening but are even able to extend their business lending. 相似文献

This paper tests the efficiency of the football betting market and develops a model of the determinants of the closing spread. The empirical results suggest that the football betting market is not perfectly efficient. The evidence also suggests that, contrary to previous studies, gamblers that do bet the long shots are acting as rational individuals attempting to maximize their return for a given level of risk. Finally, at least six variables were found to be statistically significant factors in determining closing spreads in the football betting market. 相似文献
