It explores that the objectives behind the introduction of Islamic finance and banking system were the elimination of capitalist banking interest, exploitation of poor segment of the society and the establishment of an economic system which may lead to sustain a balance economic order and social justice. In this context, it intends to analyze the mode of leasing provided by Islamic Banking system in the light of the objectives of Shari＇ah and discloses that although Islamic Banking system is based on the principle of mudarbah, musharkah and Ijarah and deals with the customers in that context, yet apparently, the effects of these transactions are not much different from capitalist modes due to same consequences and effects of these transactions. It thus, provides a comparative analysis of the issue, i.e., mode of leasing at both Islamic and capitalist Banks. It argues that a common man can not avail Islamic financing/leasing if he lacks financial resources. If a poor person tries to purchase something by way of ijarah through Islamic Banking finance, he does not find any difference in the payment of the total cost between capitalist mode of leasing and Islamic mode of ijarah. Hence, this article concludes that although Islamic financing achieved a remarkable development among the Muslims, yet there is a need to revise the policy and system of Islamic financing in the light of the objectives of Shari＇ah. It also concludes that the mode of leasing provided at Islamic Banks does not accomplish the objectives of its establishment which is public interest. At present, this system is unable to assist the poor segment of the society or to provide ease to them.展开更多

Based on available data from 64 countries over the world, the author tried to evaluate the effectiveness of the banking sectors in those countries through the view point of the data envelopment analysis approach to define how the global banking systems is under the effect of the current crisis. Findings from the research showed that banking systems in advanced economies are still more effective than in developing countries. Moreover, it explained the effect of the current financial crisis, the role of public finance （and the government）, and the development of the （privately） commercial banks to the effectiveness of the banking sectors. The research also explained some determinants that can affect the effectiveness of the banking system, including inflation, bank concentration, and level of economic development.展开更多

Similarly, it cannot tighten the credit loan by raising the interest rates of deposits and loans, but it can stimulate the growth of credit loans. The soaring CPI, stock prices and housing prices do not result from excess liquidity. On the contrary, excess liquidity and its growth restrain their rapid growth.展开更多

Thus, various policy proposals have been submitted by some scholars. The author holds that whatever form it may take, reducing trade surplus would harm China’s economic development. On the other hand, it is difficult to boost domestic consumption by increasing the resident spending on food, clothing etc. In order to consolidate the policy of domestic demand, it is important to separate production and non-production investment and create better economic conditions by accelerating the development of non-production investment and increasing the supply of "housing, traveling and education" related consumption.展开更多

People are open to accepting new technologies as the need for modernization is increasing every single day. Blockchain is one of those new and revolutionary technologies that will have a significant impact on the market and industry. In layman’s terms, Blockchain is a data structure that stores transactional records while also ensuring security, transparency, and decentralization. There is a digital signature on every transaction on a blockchain, which proves the authenticity of the blockchain. In a Blockchain, data is stored which is tamper-proof and cannot be changed as it uses encryption and digital signatures. To change a record on a blockchain, one needs to change several records, and one needs to change the distributed ledger. That’s why it’s quite impossible to change the data which has already been entered into a Blockchain. The Blockchain is a technology that will allow transactions simply, safely, effectively, and also safely. This is a very promising technology. It’s already in a lot of places. It can also solve any problem in the banking sector. This technology became famous after introducing the first cryptocurrency, which is known as bitcoin. Right now, there is a huge problem with banking, and the Blockchain can solve these problems. This paper will demonstrate transacting over a secure, blockchain-based network and therefore eliminate the need for intermediary entities. This paper is a review-based paper that provides the application and opportunities of the Blockchain in the banking system. The purpose of this paper is to provide a review of the application and opportunities of the Blockchain for a secure banking system. In this review investigation and analysis of this paper at the beginning, related work from other authors in the same fields has been discussed. Then the working method of the Blockchain technology has been introduced with analysis. The use of blockchain technology for secure banking has been discussed. The main achievement of this paper is to demonstrate how the Blockchain works and how it can be useful in the secure banking industry.</span>展开更多

Owing to low efficiency, lack of capital, and a high rate of bad debts over time, however, the system was weak and ineffective. In order to redress the situation, late last century the Chinese government launched reforms to streamline these four commercial banks and their operations. The banks subsequently set up asset management companies to buy back and resolve non-performing assets. Their operational structure was also upgraded and optimized so as to improve management efficiency and economic performance.展开更多

We find that relationships between earnings quality and new short-term loans, long-term loans and total loans in listed companies changed significantly after the banking system reform, especially in stateowned listed companies. Further investigation shows that due to the influence of rent-seeking, banks have eased the earnings requirements of non-stateowned listed companies. These findings enhance our understanding of the economic consequences of the banking system reform and of credit discrimination under the new regime.展开更多

文摘Increasing the required reserve ratio under the circumstances of immense excess reserve cannot tighten the money supply; it can, however, avoid loosening the money supply. Similarly, it cannot tighten the credit loan by raising the interest rates of deposits and loans, but it can stimulate the growth of credit loans. The soaring CPI, stock prices and housing prices do not result from excess liquidity. On the contrary, excess liquidity and its growth restrain their rapid growth.

文摘This paper investigates credit allocation before and after the 2003 banking system reform in China. We find that relationships between earnings quality and new short-term loans, long-term loans and total loans in listed companies changed significantly after the banking system reform, especially in stateowned listed companies. Further investigation shows that due to the influence of rent-seeking, banks have eased the earnings requirements of non-stateowned listed companies. These findings enhance our understanding of the economic consequences of the banking system reform and of credit discrimination under the new regime.
