能源结构调整的税收政策选择

能源是经济发展的动力,常规化石能源储量限制及其带来的环境问题已经成了经济发展的瓶颈因素,发展丰富、清洁的新能源极为迫切,但在现行市场机制下,能源产业的外部成本和外部收益均未得到有效体现,能源市场的发展存在着市场失灵,为此,可以通过附加税收政策内化常规化石能源的外部成本和优惠税收政策内化新能源的外部收益,以实现能源结构的调整。     

准确的定位是期刊腾飞的翅膀

定位是期刊的命根子。当今,在电视,特别是互联网等新媒体的挤压下,在读者对刊物阅读的品位情调、价值取向日趋个性化的形势下,将期刊置于大市场环境中,对其进行全面而客观的审视与评估,适时地调整定位坐标是期刊生存、发展的客观需要。     

基于不完全信息动态博弈模型的报价策略研究

目前应用博弈论对价格谈判所进行的研究大多集中于讨价还价问题,而关于报价问题的研究往往依靠定性分析。因此本文建立了一个关于报价策略的三阶段不完全信息动态博弈模型,并通过求解证明：在谈判双方信息对称的条件下,无论对买方还是卖方来说,“抢先报价”都是占优策略。在买卖双方都采取“抢先报价”策略时,报价顺序博弈的结果具有不确定性。在现实中买卖双方往往会通过各种其他手段来达到抢先报价的目的。     

房价与城市化的关系——基于省际面板数据的实证分析

城市化水平与住房价格的动态经济模型表明,城市化速度的上升会导致房价的迅速上涨：基于省际面板数据的实证研究也发现各地区房价对城市化率的弹性均为正值,表明城市化水平对房价具有正的积极影响。因此,应实行地区差异化的房地产业发展规划与城市规划,尊重经济规律,确立切实可行的房地产宏观调控目标,实行稳健的可持续的城市化战略,通过这些措施促进中国房地产业与城市化协调发展。     

谈国家助学贷款的贷后管理问题

国家实行助学贷款政策帮助贫困学生圆了大学之梦,得到了广大人民群众的拥护。但在实践中出现了新的问题,那就是还款率低。为了更好地解决这一实际问题,必须切实加强对学生思想政治特别是诚实守信教育、建立信用信息查询制度,依靠制度、机制促使还贷,调整政策加大还贷力度,切实做好国家助学贷款的贷后管理工作。     

系数修正法在标定地价评估中的应用

本文从务实的角度出发, 系统阐述了系数修正法在标定地价评估中的应用。文中首先论述了系数修正法的基本原理,然后详细分析了影响地价的各种因素并给出了利用系数修正法评估地价的具体步骤, 最后通过评估实例进行了说明     

Impact of the 2014 Suspension Agreement on sugar between the United States and Mexico

In December 2014, the U.S. and Mexico agreed to a suspension agreement that set a $22.25/cwt import price floor on U.S. sugar imports from Mexico. A partial equilibrium trade model was developed to estimate the economic impact the agreement would have had if it had been in effect from 2008 to 2014. In years when the price floor would have been binding, on average, U.S. producers would have gained $138 million and Mexican producers would have lost $218 million. However, total Mexican welfare would have actually increased by $11.5 million. Furthermore, the average price floor that would have maximized total Mexican welfare over that period is $22.76/cwt. Also, under certain supply and demand elasticity conditions, the average price floor that would have maximized joint U.S. and Mexican producer welfare over that period is $21.91/cwt. The latter two estimates are both close to the actual price floor agreed to in the 2014 Suspension Agreement.     

Testing vertical price transmission for Vietnam's Robusta coffee

Vietnam has undergone market reforms over the last three decades; and as a consequence, the coffee sector has become increasingly market‐driven. The success of the government's liberalisation policies in terms of market efficiency is investigated by examining the transmission of both positive and negative price changes for Robusta coffee between export and farmgate prices. We used a threshold vector error correction model and high‐frequency daily data. The primary result here is that of a symmetric price transmission between export and farm‐level prices. This result holds when tested with weekly price data, derived from the daily data. Farmgate prices respond faster to decreases than increases in export prices when the long‐run deviation exceeds a certain threshold. These price changes are transmitted within several days. This research also confirms the importance of transaction costs, and other price frictions mostly ignored in prior analyses for coffee.     

江苏省虚拟水贸易结构调整研究

基于江苏省2012年投入产出表及水资源公报的统计数据,运用修正后的投入产出模型,定量计算江苏省贸易用水强度、虚拟水净输出量,并通过调整贸易结构,最大化实现节水效应。研究表明:2012年江苏省虚拟水贸易整体上呈现净流入,有利于节约省内水资源;从贸易额调整来看,在设定的5%、10%、15%3个调整幅度的基础上改变传统的贸易输出、输入结构,化学产品、煤炭采选产品部门出现大规模节水效应,随着调整幅度的增加,净输出量大的部门节水效应越来越大。江苏省虚拟水贸易是当前实现资源节约与经济发展的重要方式。
