Analysis on Balance Gap between Saving and Credit Account in China

In China, the balance gap of credit and saving account emerged in 1995, and its amount enlarged since then. By the end of Dec. 2005, with 28.7 trillion RMB saving balance and 19.5 trillion RMB gross credit account balance, the gap between saving and credit account was as large as 9.2 trillion RMB, which indicated a 67.8% of credit/saving ratio. Some believed this phenomenon was resulted from on one hand, the rapid growth of saving account; and on the other hand, relatively slower expanding of credit account. Some believed cooling down cash demand was behind the gap, while others claimed the balance gap caused dead capital and inefficiency service of saving account. In fact, the balance gap between credit and saving account might not necessarily relate to dead bank capital. And the phenomenon itself could not indicate the down-tendency of finance power that underlay economy. Nevertheless, it was liquidity not the balance gap should be regarded an index of capital situation in financial organizations. Therefore the balance gap between saving account and credit account could not be viewed as criteria against liquidity position. Solution of this problem should lay in boosting financial innovation among commercial banks, expending capital market and encouraging or permitting commercial banks as well as state-owed funds to enter share market and so on.     

Qualitative Input–Output Analysis of the Indian Economic Structure

Qualitative input–output (IO) analysis can be considered mostly in terms of a graph-theoretic formulation, which involves the construction and use of an adjacency matrix, derived from a binary transformation of the IO coefficient matrix. Classical attempts at qualitative IO analysis have derived the structure from the direct IO coefficient table. In more recent attempts, greater sophistication has been achieved by incorporating a degree of quantification into the qualitative analysis. Also, the concept of important coefficients (IC) has been used for the construction of the adjacency matrix. The present study is carried out along these lines for the Indian economy.     

中国盒融产业集聚水平测度

本文利用区位基尼系数、区位熵指数、CR5指数埘中国金融产业2001-2010年的集聚水平进行了测度。结果表明,金融业具有较为明显的集聚特征,且总体集聚程度不断增强,金融资源主要集中在于东部地区,其中北京、上海的金融集聚程度最高,而中两部地区金融集聚程度较低,在今后的发展过程中应注重金融中心的辐射效应,     

棉纤维成熟度指标间关系的研究

在棉纤维成熟度的指标中,棉纤维的成熟系数和成熟度比,反应的是棉纤维个体的成熟情况,两者之间可以用数学关系式进行表达;成熟纤维百分率反映的是棉纤维集合体的成熟情况,不能由一根棉纤维的成熟情况描述全部纤维集合体的成熟情况;成熟系数、成熟度比与棉纤维成熟纤维百分率之间的关系不确定,不存在必然的数学关系式。     

物业税改革对地区间税收分配差距的影响

本文通过对地区间税收分配差距指标的分析,认为开征物业税很可能会扩大我国地区间税收分配差距。在当前物业税改革过程中,需要充分重视该问题的研究。建议将土地出让金制度和财政转移支付制度改革,作为物业税改革总体规划的重要配套措施,统筹设计相关制度,以有效防止地区间税收分配差距的不合理扩大,促进地区间经济协调、平衡发展。     

中国人口老龄化对人身保险市场发展的影响分析——基于省际面板数据的经验分析

本文基于我国30个省、市、自治区(除西藏外)1997年～2008年度面板数据,运用面板回归的计量分析方法,对中国老龄化背景下人身保险市场的发展情况进行了研究.中国人口老龄化的到来,为人身保险市场的发展既创造了机遇,也带来了挑战,本文经过反复的实验估计,认为老龄化对人身保险市场的推动作用要大于其阻碍作用,并且老龄化程度越...

幂级数的除法

本文从复变函数展开为幂级数的待定系数法出发,提出了幂级数的除法的概念,并给出了幂级数的除法的运作方式,从而有效地解决了待定系数法比较繁杂这一困难,同时保证了运算结果的准确性。     

经济发展、个人所得税调整与城镇居民收入差距

通过收集中国28个省、市、自治区2003—2012年的面板数据一方面验证库兹涅茨曲线在中国是否成立,另一方面,在库兹涅茨曲线基础之上验证2006年和2011年个人所得税调整对中国城镇居民收入差距的影响。实证研究结果表明,库兹涅茨曲线在中国显著存在,而且当人均实际GDP达到20 000元(2003年不变价格)左右时,中国城镇居民的收入差距随着人均GDP的进一步增加而逐渐下降,与跨国面板的实证结论一致。在该库兹涅茨曲线基础之上2006年个人所得税调整对城镇居民收入差距的影响不显著,而2011年的个人所得税调整则显著地降低了中国城镇居民的收入差距。
