Does too much government spending depress the economic development of transition economies? Evidences from dynamic panel threshold analysis

This paper investigates the relationship between government size and economic growth and determines the optimal level of government spending to maximize economic growth. The paper applies a dynamic panel data analysis based upon a threshold model to test the threshold effect of government spending in 26 transition economies over the period spanning 1993–2016. According to the analysis results, government expenditures have a threshold effect on economic growth, and there is a non-linear relationship depicted as an Armey curve in these transition economies. The findings indicate that a government size above the threshold government spending level adversely affects economic growth, while a government size below the threshold level has a positive effect. Furthermore, there is a statistically significant relationship between the two variables above and below that optimal level, even if we divide the sample into developed and developing countries. Our findings suggest that governments in transition economies should consider optimal government size at around the estimated threshold level to support sustainable economic growth.

Integrating science and local knowledge in environmental risk management: A decision-focused approach

This paper explores how a structured decision process, based on methods from the decision sciences, can contribute to the integration of local and scientific knowledge in environmental decision making. Emphasis is placed on the use of key decision structuring steps and analytical tools to help ensure the systematic treatment of both fact-based and value-based knowledge claims. Practical methods are discussed for communicating and evaluating values and technical information across participants and cultures in ways that are methodologically rigorous and encourage different sources of credible knowledge to be considered on equal footing. Examples are presented from water use planning in British Columbia, Canada, where stakeholder consultations at 22 hydroelectric facilities demonstrate specific techniques that can be used to clarify values, to explore hypotheses, to clarify uncertainties, to identify and evaluate options, to make value-based choices, and to facilitate mutual learning.     

The Application of Sensitivity Analysis on Comprehensive Transportation Evaluation

Comprehensive transportation evaluation objects using multi-objective decision method is a process of choosing the best one from a few objects through calculating, analyzing, and comparing the index system. The result may be different because of the difference of the index weight and index value. Therefore, sensitivity analysis should be one of the necessary parts of the decision-making. It is desired to give the index with higher sensitivity and its varying scope to control the index strictly during the execution process. This paper derives transfer index weight, which changes the rank evaluation order of the projects. Meanwhile, a simple, effective and practical method based on sensitivity district and sensitivity matrix is proposed for the sensitivity analysis of decision-making. As an example, the index sensitivity in decision-making of some provinces comprehensive transportation objects, and their influence on the final decision are discussed.     

信任、不信任与控制关系及其应用研究的现状与思考

信任、不信任与控制之间的关系及其应用,已成为当代众多社会科学学科研究信任问题的子焦点之一。我们依据近年国外有关文献的调研,认为：缺乏一个以当代众多社会科学领域重要的理论命题为基础的、统一的科学、严谨、结构合理的三者关系的分析框架,是当前深化和推进有关研究必须克服的一个障碍。

武陵山片区旅游节点交通畅达性研究

区域旅游节点的交通畅达性对区域经济发展具有强劲的推动作用,区域旅游节点的交通畅达性优劣取决于内部的连通性和外部的可达性。文章基于因子分析法分别就高等级公路、高速公路、普铁、高铁(动车)、民航航线等因素对武陵山片区内各旅游节点的交通畅达性的影响进行了评价分析,对各旅游节点的畅达性进行了排名;并选取2010、2014、2018年等3个时间节点数据导入GIS生成3个片区旅游交通图。研究发现:①重庆、武汉、长沙、贵阳四大中心城市的交通连线支撑起武陵山片区的交通网络,片区旅游节点之间的畅达性逐步提升;②处于武陵山片区外围重庆、武汉、长沙、贵阳四大中心城市交通大廊道上的旅游节点之间畅达性处于片区前列;③同一省市或同一传统旅游线路的旅游节点连通性较好,分属不同省市的旅游节点之间连通性普遍较差;④历史上,山高谷深、交通闭塞,各地市自然旅游资源丰富多样,文化旅游浓郁独特,近年来,武陵山片区旅游发展与交通建设相互推拉,呈现良性发展。

湖南省农民收入水平地区间差异实证分析

本文应用定性分析与定量分析相结合的方法,通过对湖南省农民收入水平地区间差异的对比分析和影响农民收入水 平各因素的相关性分析,说明人均国内生产总值、第一产业比重、城市化水平对农民收入均有重要影响。造成湖南省农民收入水 平地区间差异的原因在于:农村教育发展上的差异、非农产业发展上的差异、市场化发育程度上的差异、资源环境条件上的差异。     

非农化经营与农业上市公司经营绩效——理论分析与实证检验

我国农业上市公司非农化经营现象甚为严重,这一现象对农业上市公司经营绩效的影响引起了社会各界的广泛关注.农业上市公司非农化经营主要可以归纳为产业层次和企业管理层次这两方面成因.农业发展不足的现实成为我国农业上市公司非农化经营取向的最大产业背景因素.文章运用农业比较利益理论、外部性理论以及多元化经营理论,形成对农业上市公司非农化经营成因和非农化经营对绩效影响的理论分析框架.通过实证分析所得出的结论是:非农化经营从整体上减损了农业上市公司经营绩效.研究认为,政府应该着力在改善农业投资经营环境和制度创新上下功夫,才可能真正引导农业上市公司专注于农业上来;同时认为,目前农业上市公司主要应当实施农业专业化经营战略,在条件具备的情况下才实施与主业相关的多元化战略,现阶段应尽量避免非相关多元化经营.
