促进我国区域贸易的探讨

区域贸易是指不同区域之间进行商品交换的活动。历史证明:存在区域贸易的区域比那些自给自足的封闭型地区更能够促进国民经济的发展。目前,我国各省区之间的区域贸易仍然比较弱,地方保护主义仍旧盛行。各地区没有充分利用各自的比较优势、以专业化生产来提高各自的贸易利益。本文通过对我国地区贸易冲突及生成机制的研究,找出出现这种现象的根本原因。同时,借鉴美国促进国内区域贸易的措施,给我国合理的区域贸易建言献策。

提问式教学法在“儿科护理学”教学中的应用

探讨提问式教学法对“儿科护理学”教学的影响，将学生随机分成实验组和对照组。对照组采用传统教学法，实验组采用提问式教学法。结果为提问式教学法在“儿科护理学”教学中优于传统教学法。提问式教学法可以激发学生学习积极性，提高学生解决问题的能力和学习成绩。     

我国央行公开市场操作策略与流动性效应

本文检验了不同操作策略下中国央行公开市场操作流动性效应。通过构建并计算央行公开市场操作指标值，根据取值区间将公开市场操作定义为五种操作策略。本文采用2006年10月至2012年3月的数据，估算了每月超额准备金，并计算出实际的公开市场操作指标值，利用排序自回归法证实了央行公开市场操作对利率有非线性影响，进一步建立非线性多阈值自回归模型，研究了不同操作策略的公开市场操作对3个月短期市场利率的影响。实证结果表明央行公开市场操作可分为四种策略，主要表现为防御性功能，但不存在周流动性效应。     

U.S. Canned Tuna Supply and Demand

Abstract

A 3SLS econometric model is used to estimate price elasticities of supply and demand for domestically produced and imported canned tuna in the U.S. market. In addition, a VAR model is developed to examine the relations between imports and domestically produced canned tuna. For domestically produced canned tuna, a 3SLS estimation of a structural econometric model yielded a coefficient for price elasticity of supply of 0.2 and of own-price demand of ?0.3. Such price inelasticities are expected of a fishery exploited at or near its maximum yields (inelastic supply), and a consumer product widely viewed as almost a necessity in a well-stocked pantry (inelastic demand). In addition, the model yielded a cross-price elasticity of demand with respect to the price of imported canned tuna of 0.45. Additional results include an income elasticity U.S. demand for domestically packed tuna of 0.83; a cross-price elasticity with the price of bread (a complement) of ?0.33, a cross-price elasticity for the price of ground meat (a substitute) of 0.30. With respect to imported canned tuna in the U.S. market, the corresponding elasticities estimated in the model are ?1.3 (own-price demand), 3.5 (income elasticity), ?1.2 (cross-price with the price of bread) and 2.5 (cross-price with the price of ground meat).

For canned tuna company managers, the results provide useful information about the likely effects on sales that would come from their own price changes, from changes in the price of imported canned tuna, and from price changes in the markets for complementary and substitute products. They can also use our results in discussions with U.S. trade negotiators, who are frequently faced with disputes over tariffs, market access, and other trade issues.     

浅析音乐在中国诗歌欣赏过程中的重要作用

诗歌是诗人情感的渲泄,我们除了要感受诗歌的情感外,还要品味诗歌形象凝练的语言,体会诗歌和谐的韵律,体会它鲜明的节奏。音乐与诗歌在内涵上有着本质的联系,在欣赏过程中配以音乐,会增加诗歌的感染力,本文主要论述音乐在诗歌欣赏过程中发挥的重要作用。     

Interaction of size,book‐to‐market and momentum effects in Australia

This study seeks to disentangle the effects of size, book‐to‐market and momentum on returns. Initial results show that each characteristic has a role in explaining returns, but that there is interaction between size and momentum, as well as between size and book‐to‐market. Three key findings emerge. First, the size premium is the strongest, particularly in the loser portfolios. Second, the value premium is generally limited to the smallest portfolios. Third, the momentum premium is evident for the large‐ and middle‐sized portfolios, but loser stocks significantly outperform winner stocks in the smallest size portfolio. When these interactions are controlled with multivariate regression, we find a significant negative average relation between size and returns, a significant positive average relation between book‐to‐market and returns, and a significant positive average relation between momentum and returns.     

自由贸易区战略助推人民币区域化——基于CAFTA的实证研究

2008年全球金融危机的爆发使得以中国为代表的新兴经济体开始寻求本币国际化的进程。自由贸易区战略和人民币区域化之间有何关联?本文根据人民币的事实境外流通状况和发展趋势,选定CAFTA作为人民币区域化的辐射范围,分析人民币区域化的贸易总量和结构条件后认为:(一)人民币区域化的贸易总量条件已经具备,在贸易结构条件上则喜忧参半;(二)人民币区域化必须具备相应的贸易结算基础,否则人民币区域化将无法得到实体经济的有力支持;(三)自由贸易区内区域性贸易逆差在推动人民币区域化进程中有一定作用。最后提出运用自贸区战略的巧实力助推人民币区域化的政策建议。     

孟子民本经济观探析

孟子秉持着“民贵君轻”、“民事不可缓”的民本情怀，提出了“薄税敛”以“藏富于民”的富民经济理想。正是基于这种富民经济理想，孟子因而在施政次第上首倡“制民恒产”的土地经济政策，提出了使民“养生丧死无憾，王道之始”的养民经济观；其次，在商业经济领域，孟子又提出了“互通有无”的“自由贸易”的惠民经济观。     

An acceptance model for an Internet protocol television service in Korea with prior experience as a moderator

This study examines the effect of users' prior experience on the adoption behaviour in the Internet protocol television (IP TV) service domains. This article proposes a new acceptance model for an IP TV service considering the moderating effect of experience and verifies the model with an empirical study. Respondents are classified into either experienced or inexperienced groups according to their prior experience with the IP TV service. The results indicate that motivational factors used in our study affect behavioural intention. In addition, this study shows that the influence of extrinsic motivational factors on the behavioural intention are stronger for the experienced group than the inexperienced group and the influence of intrinsic motivational factors on the behavioural intention are stronger for the inexperienced group than the experienced group. This article concludes with study implications, as well as limitations and future research directions.
