中美汇率利率互动效应研究：2000-2011

本文应用非线性平滑转换模型研究了2000-2011年中美名义汇率与名义利差之间的动态非线性关系．研究发现：中美名义汇率与名义利差之间存在着负相关关系,汇率对利率的影响呈现出非对称性特征。当名义汇率在7—8之间时,汇率的变动会引起两国利差的较大变动;当人民币被高估或低估时,汇率对利率的影响程度大大降低。     

化石能源耗竭与气候变化约束下的经济低碳转型

本文构建了一个包含产品生产、技术研发、新能源生产和温室气体减排四个部门的内生增长模型;并运用最优控制理论,研究了在化石能源耗竭与气候变化约束下,经济低碳转型中的一系列关键变量的长期行为方式和中短期平衡增长路径;进而刻画了劳动力在各部门间的配置和转移、化石能源价格、排放空间价格对能源结构、碳强度、消费、单位劳动碳减排量、单位劳动产出等变量的影响机制;同时揭示了运用一些政策工具实现经济低碳转型的时机选择。     

外贸可持续发展的战略研究——以湖南省为例

对外贸易是推动湖南经济快速增长的重要力量.面对当前国内外形势发生的一系列重大变化,外贸发展已进入重要的战略转型期.湖南要实现对外贸易发展的新突破,在更大范围、更广领域和更高层面上参与国内外竞争,就必须加快转变外贸增长方式,可持续发展的外贸发展方式是湖南走向成功的必经之路.本文在介绍新世纪以来湖南对外贸易发展基本状况的基础上,结合运用图表数据分析,并运用经济管理相关理论知识对湖南近年来外贸可持续发展状况进行综合评价分析,最后就湖南外贸可持续发展的战略选择提出相关建议.     

住房保障与财富效应逆转——基于平滑转换回归方法的实证分析

本文采取非线性的平滑转换回归方法,对我国保障房供给影响财富效应的程度进行了研究,结果表明:保障房的供给会使得房地产价格的财富效应发生V型逆转,即当保障房供给处于低水平阶段时,房地产价格的财富效应为负向,房价上涨会抑制消费增加;当保障房供给处于高水平阶段时,房地产价格具有正向的财富效应,房价上涨促进消费增加。这说明存在一个保障房供给的最低门槛,只有跨越这个门槛,才能有利于发挥房地产价格的财富效应,进而促进消费。从对全国各省份的数据分析发现,西部地区的大部分省份已经跨越了保障房供给的最低门槛,而东部地区较多的省份,连续几年都低于这个门槛值。因此,应积极建立健全保障性安居工程的融资机制,合理协调好保障房与商品房用地之间的关系,进而促进消费。     

低碳经济转型和中国-东盟FTA贸易与环境的协调

在金融危机全面影响实体经济、世界经济加速向低碳转型的2009年,中国-东盟FTA的构建进入关键时期。尽管双方并没有因此延缓贸易自由化的推进步伐,于2010年1月1日如期建成FTA,但包括贸易与环境的摩擦及冲突在内的中国威胁论的不和谐之音还是若隐若现。低碳经济转型为中国-东盟FTA建设贸易与环境的协调提供了极为重要的契机和内部驱动力量。     

How markets will drive the transition to a low carbon economy

This paper investigates the driving factors behind the transition to a low carbon economy. Here, we offer a two-part analysis: First, we examine the factors leading to the current level of cleantech development. To do so, we examine the impact of country-level economic variables (real GDP, market return, and turnover) and country-level institutional variables on patent intensity. Results from this analysis show that cleantech patenting activity is fostered by a supportive institutional environment that promotes innovation and low-carbon development through carbon pricing policies, country-level public R&D expenditure and human capital. Second, we extend the notion of ‘path creation’ to map out different pathways for cleantech development on a country-level within a real options framework, and offer a corresponding valuation of cleantech patents. Our estimates of total wealth creation through the development of cleantech patents by 2050 range from US$10.16 to US$15.49 trillion dollars (13%–20% of the world GDP in 2017) with investment growth from US$2.93 to US$3.71 trillion (3.7%–4.7% of the world GDP in 2017). The results from our analysis suggest that market forces will drive the transition to a cleantech economy.     

粤港澳大湾区创新生态系统内部耦合时空演化及空间收敛分析

在构建以国内大循环为主体、国内国际双循环相互促进的新发展格局下，高效协同的区域创新体系有助于将粤港澳大湾区三地建设成为具有全球影响力的科技创新中心。通过构建创新生态系统综合评价指标体系，采用耦合协调模型和空间计量模型，实证检验大湾区10个城市2007-2019年创新生态系统内部耦合协调水平、时空跃迁特征以及收敛性。研究发现，大湾区整体及各城市耦合协调度呈上升趋势，基本实现从失调衰退区到协调过渡区的转化，具体可划分为4个等级层次；大湾区创新生态系统协调耦合度存在显著的绝对β与条件β收敛趋势，即最终收敛于同一稳态水平，且城市间差距逐渐缩小。其中，经济发展水平、对外交流水平、人力资本水平对创新生态系统协调耦合度起显著正向作用。     

The non-linear impact of oil price on the oil demand

ABSTRACT

A panel smooth transition regression model was adopted to analyse the non-linear impact of oil prices on oil demand. Data for 42 countries was obtained from the International Energy Agency for the time period spanning from January 1990 to June 2017. The results indicate that a threshold value does exist. Furthermore, when the oil price was lower than this threshold value, a positive relationship between oil price and oil demand was observed. When the price of oil was higher than the threshold value, however, a negative relationship between price and demand was found.     

Did foreign exchange holding influence growth performance during the global financial crisis?

In a context of increased foreign exchange reserves holding from emerging and developing countries, this paper investigates the diminishing return of reserves holding assumption over the most severe phase of the global financial crisis (2008Q1–2010Q4). Relying on a Panel Smooth Transition Regression model, we highlight the differential effect of the accumulation of foreign exchange reserves for a set of financial vulnerabilities variables. In a specific manner, although reserves accumulation is effective above a critical threshold to cope with vulnerabilities related to the financial channel, we show that it becomes less effective beyond a certain threshold for domestic bank vulnerabilities. Our results are robust to alternative specifications.
