Equilibrium theory under ambiguity

We extend the classical results on the Walras–core existence and equivalence to an ambiguous asymmetric information economy; that is, an economy where agents maximize Maximin Expected Utility (MEU). The interest of considering ambiguity arises from the fact that, in the presence of MEU decision making, there is no conflict between efficiency and incentive compatibility (contrary to the Bayesian decision making). Our new modeling of an ambiguous asymmetric information economy necessitates new equilibrium notions, which are always efficient and incentive compatible.     

国防生对军人核心价值观认知程度的调查与分析——以昆明理工大学国防生为例

以昆明理工大学国防生为调查对象,当代革命军人核心价值观(忠诚于党、热爱人民、报效国家、献身使命、崇尚荣誉)五大精神在国防生的思想、学习、生活、军政训练等具体表现形式基础上,设计调查问卷,了解当前高校国防生对当代革命军人核心价值观的认知程度,经分析后查找国防生教育中的薄弱环节和不太被学生认可的地方,为今后教育的优化改进提供可靠准确的理论依据和数据基础。     

京津冀城市大气环境竞争力评价

从大气环境与城市竞争力的关联性入手,将大气环境风险、现状和治理纳入评价指标体系,基于组合权重的大气环境竞争力评价模型,对2013-2017年京津冀13个城市的大气环境竞争力水平进行了测评,并结合空间自相关分析和障碍度模型揭示了其空间效应及障碍因素。结果显示:京津冀城市大气环境竞争力存在明显的空间差异,呈"北部高、南部低、局部跳跃"格局,城市差距逐渐缩小;京津冀城市大气环境竞争力呈显著的空间集聚效应且存在正向相关性,空间分布格局相对稳定。     

Bioelectricity in Malaysia: economic feasibility,environmental and deforestation implications

We investigate the economic feasibility of bioelectricity production from biomass in Malaysia and its impact on greenhouse gas (GHG) emissions and storage, agricultural prices, agricultural employment and deforestation. For this purpose, we develop a partial equilibrium model that projects agricultural prices, production, imports, exports, domestic consumption and land use in 5‐year increments between 2015 and 2065. Our results show that by 2030 biomass‐generated electricity can supply 36.5 per cent of the electricity generated in Malaysia, 16 times more than the 2016 electricity supply from biomass. Increased bioelectricity production from biomass will significantly reduce GHG emissions and will help Malaysia meet its commitment in the Paris Agreement to mitigate GHG emission by 45 per cent before 2030. Our modelling shows that biomass‐generated electricity creates a derived demand for waste biomass that expands the area of oil palm plantations. The expansion lowers agricultural prices, boosts agricultural employment and leads to some deforestation as landowners clear rainforest to plant oil palm trees. Nonetheless, the deforestation does not increase GHG emissions since GHG gains from bioelectricity significantly exceed GHG losses from deforestation.     

Does economic policy uncertainty raise corporate precautionary cash holdings? Evidence from China

Using China as the research setting, this paper investigates the relationship between economic policy uncertainty and corporate precautionary cash holdings. Empirical results show a U-shaped relation between economic policy uncertainty and corporate precautionary cash holdings. Empirical analysis, in terms of ownership structure, firm size, corporate competitiveness and geographical location, further shows that (i) the effects for economic policy uncertainty in both state-owned and non-state-owned enterprises are significant, but the effect is stronger for state-owned enterprises; (ii) such significant effect is also found more strongly in small and medium-sized enterprises and highly competitive enterprises; and (iii) the effects for eastern, central and western China are all statistically significant, but the effect is strongest for eastern China.     

中国农业竞争力提升视域下的小农户发展

目前我国农业发展面临一个急需破解的重大悖论：如何在发展小农户的基础上提升中国农业竞争力。论文提出中国特色农业竞争力具有三重内涵：以生产竞争力为基本要求，以安全竞争力为战略底线，以市场竞争力为主攻方向。小农户发展对于提升中国农业竞争力有重要作用，这体现于小农户发展有助于提升农业生产竞争力、安全竞争力和市场竞争力并推动提升机制之间联动。因此，提升中国农业竞争力必须促进小农户发展，并且小农户发展有提升农业竞争力的可能性，但当前小农户发展受到内外条件的约束。据此，本文提出以下政策建议：完善政府支持、发挥小农户主体作用、发展和推广农业科技和物质装备以及将小农户融入产业链。     

贵州的脱贫和发展：基于三因子耦合的解析

贵州的脱贫和发展案例表明，欠发达地区的脱贫和发展是集合“核心设施、骨干领域、环境机遇”三大因子共同发力的结果。这一发现挑战了当代主流发展理论，并在落后国家或区域具有广泛复制的价值。这种新发展观不只是一种自洽且连贯的学说，还可作为引导明智行动的机制对待，因而深具实践意义。可以把这三个强关联性词汇转换为规范且符合逻辑的陈述以激发洞见，充实当代发展理论，同时为其他不发达地区的贫困治理和经济发展提供经验和借鉴。     

Tourism competitiveness index of the Asia-Pacific region through consistency analysis

The world’s economy shifts to a more competitive environment as globalization expands and countries have to adjust by making decisions to improve their competitiveness in all sectors. The Travel and Tourism Report, a useful tool facilitating policy-making and business decisions, allows entities to envision their ranking in the face of the travel and tourism through the creation of a competitiveness index. Focusing on Asia and the Pacific, this paper intends to investigate internal consistency of the constructs based on data analysis techniques such as correlation and reliability, essentials to broader acceptance of the index. The results indicate that high linear association between index and pillars leads ultimately to good level of consistency and highlight the lack of relationship between overall consistency and inter-class consistency. It is suggested to pay close attention to unidimensionality of constructs and inter-relation between variables while building an indicator system as it increases its reliability.
