管理者金融危机经历影响企业金融化水平吗？——基于中国上市公司的实证研究

文章以我国2008—2017年非金融上市公司为样本，结合“烙印理论”，考察了管理者金融危机经历对非金融企业金融化水平的影响，研究发现：管理者的金融危机经历对其所在企业的金融化水平具有显著的正向影响，在一系列的稳健性检验后，该结论依然成立。且该效应在融资约束严重的企业和制度环境较好地区的企业中更加显著，而在金融危机期间遭受财务困境的企业中受到明显抑制。拓展的研究表明，经历过金融危机的管理者持有金融资产的动机并不单一，但获利动机更强烈。最后文章还发现，管理者的获利动机和管理者自信可能是金融危机经历影响企业金融化水平的关键作用机制。文章从企业微观层面拓展了非金融企业金融化水平的影响因素研究，并对企业管理者经历对非金融企业金融化的影响及作用机制研究进行了一定的探索。     

Assessing Financial Performance of Malaysian Islamic and Conventional Commercial Banks Using Financial Ratios

A rapid growth of Islamic banking has led the Malaysian economy to gaining greater prosperity than before. Presently, there are more than 20 Islamic banks operating in Malaysia. Financial ratios calculated from the categories of liquidity, profitability, risk and solvency, and efficiency of banks can be used to gauge the overall financial performance of the banking industry. The objective is to assess the overall performance of Islamic banks as well as conventional banks in Malaysia using financial ratios. The findings indicated that conventional commercial banks in Malaysia do have better quality assets, are more liquid, and are more profitable than Islamic banks. Total expenses in conventional banks are much higher, which may affect profitability and the significant amount of non-performing loans （NPLs）, thus increasing solvency risk. The findings show positive insights of Islamic banks, whose confidence and trust are rising, over a short period with strong improvements in asset utilization, effective management, and expenditure control. This comparative study clearly identified that conventional banks are better financial performers compared to Islamic banks in Malaysia during the period of 2006-2010.

基于指挥信息系统的通信部队指挥应用分析

随着指挥信息系统在全军的广泛运用,指挥方式由传统的"树状"改变为"网状"、"扁平状"。然而现通信部队在开展指挥信息系统训练、应用上还存在一定的短板,在提高整个部队的指挥能力上无法提供高效支持,文章对通信部队的指挥信息系统在实际运用上进行了初步分析,并指出了目前存在的不足,对如何提高通信部队利用指挥信息系统提高整体作战能力提出了对策和建议,对提高指挥信息系统在实际中的应用具有积极意义。     

A quantitative perspective of Porter's industry forces framework for investment analysis

Porter's industry forces framework is an important tool for external analysis of firms, but its qualitative nature presents numerous limitations to be used in investment analysis. This study introduces a quantitative perspective of the framework using financial information proxies. This allows investors to gauge the external factors quantitatively and to gain enhanced framework usability. In order to test its validity, the correlation movements of our quantitative perspective have been analysed. For demonstration of enhanced usability, our quantitative perspective, alongside machine learning models, was used to predict business performances. The empirical results indicate that our quantitative perspective of the framework corroborates with its original definition and that it exhibits enhanced usability than the original framework.     

Spontaneous economic order

This paper provides attempts to formalize Hayek’s notion of spontaneous order within the framework of an Arrow-Debreu economy. Our study shows that, if a competitive economy is sufficiently fair and free, a spontaneous economic order will emerge in long-run competitive equilibria so that social members spontaneously occupy an unplanned distribution of income. Despite this, the spontaneous order may degenerate in the form of economic crises whenever an equilibrium economy approaches the extreme competition. Remarkably, such a theoretical framework of spontaneous order provides a bridge linking Austrian economics and neoclassical economics, where a truth begins to emerge: “Freedom promotes technological progress”.
