湖南省无论从率先开展银行卡助农取款服务,还是推广银行卡升级换代等都取得了一定成就。但也存在着持卡人用卡情况仍欠佳、用卡领域狭窄、服务欠完善、环境欠佳、法规环境欠优化等诸多问题。已成为银行卡产业发展的瓶颈。改变信用卡发展严重滞后现状,增加居民收入与改变消费观念,加大银行卡推广力度,加快银行卡产品创新,创造良好的银行卡受理和法规环境。拓展并规范信用卡市场无疑是一条有效途径。同时,应大力培养消费者良好用卡理念,避免“睡眠卡”的出现,提高持卡人用卡频率,增强用卡安全意识。推动银行卡产业的发展。 相似文献

A worldwide increase in household debt since the turn of the century has created considerable concern about the indebtedness of households, especially those in emerging economies that have been hit particularly hard by the global economic slump. In this study, the credit consumption of consumers in Swaziland (N = 264) was investigated by means of a survey that aimed to identify and describe factors that encouraged consumers' use of credit, the influence of credit on their buying behaviour when choosing major household appliances or furniture as well as consumers' knowledge of the conditions of credit facilities that were available for their use in retail. Findings revealed that consumers unequivocally appreciate the convenience that is associated with credit, specifically to cope with unexpected purchases, to benefit from special offers and opportunity to afford expensive goods. These advantages apparently negate the negative consequences such as high interest rates and strain on household budgets. Mean scores that were obtained in the knowledge test that only reflected upon credit agreements that respondents have actually entered into in the past, confirmed their ignorance pertaining to their contractual obligations and their consequent vulnerability. Consumers' age and gender seem to have noteworthy consequences for efforts to enhance informed consumer decision‐making. Younger females were significantly better informed that their older counterpart while the reverse was true for males, although differences were not significant. The significant inverse relationship between income and the LS‐means for the credit knowledge test differ from findings in developed countries and provide valuable opportunity for further investigation. 相似文献

根据刑法原理,单位犯罪应适用追诉时效制度。在现行刑法规定下,单位犯罪中单位的追诉时效期限应以单位责任人员中最长的追诉时效期限来确定;单位责任人员的追诉时效期限应以自然人的追诉时效期限来确定。从立法的角度来看,单位犯罪的追诉时效制度还有待通过刑法的修订来进一步完善。 相似文献

Analyses were carried out on financial compensation to avoid loss of tropical forests and related carbon (C) emissions when marginal financial yield declined for land-use options with extended areas, and when a risk-averting perspective (modeled according to financial theory around the capital asset pricing model) is assumed. The approach in this study was to consider natural forest, forest plantation, pasture, and cropland simultaneously to investigate how an optimized land-use distribution may reduce the amount of compensation necessary to avoid C emissions from forest loss.The financial compensations derived were as high as US$ 176 per hectare per year when comparing natural forests only with the most profitable alternative (croplands). However, compensation decreased to US$ 124 for risk-neutral decision-makers, who would strive for optimized land-use allocation, and to only US$ 47 per hectare per year for risk-avoiders, who would look to maximize the reward-to-variability ratio. Sensitivity analyses indicated that the compensation under risk-aversion increased much less than under risk-ignoring when increased productivity of agricultural land-use or growing demand for agricultural products was simulated. It was concluded that considering appropriate diversification strategies and the well documented human behavior to avoid risks is an important step in developing cost-effective compensation policies. 相似文献
