安徽省城乡居民收入与消费关系的协整分析

本文运用协整和误差修正模型,以安徽省1984—2006年的统计资料为样本,构建了城乡居民长短期的收入与消费模型,对城乡居民收入与消费之间的关系进行了分析。结果表明：安徽城乡居民的收入和消费之间各自存在着长期的均衡关系,在人均消费的层面上,城镇居民对于消费增长的支持大于农村居民,农村居民的消费需求还有待提高。     

中国航天产业后向关联效应及前向关联效应研究——以上海数据为例

航天产业是当今世界最具挑战性和产业关联性的高科技领域之一,并已成为国家的战略性高技术产业.文章利用投入产出分析技术和上海最新投入产出表数据,通过计算和分析直接消耗系数、完全消耗系数、直接分配系数、完全分配系数、影响力系数和感应度系数等指标,研究了航天产业对其他产业的后向关联效应与前向关联效应,揭示了航天产业与其他产业关联的内在机理.最后从促进产业关联的角度提出了加强航天产业发展的政策性建议.     

Welfare and equity impacts of cross-border factor mobility in Bangladesh: A general equilibrium analysis

We develop a dynamic computable general equilibrium model with cross-border factor mobility to assess the impacts of a foreign wage shock and the effects of counteractive policy measures in Bangladesh. The model features migration of workers and foreign direct investment (FDI) in the ready-made garments (RMG) sector. Our simulation results show that returning migrants induced by a foreign wage fall would reduce household welfare by lowering wages and increasing unemployment, particularly for unskilled workers in the domestic labor market. To counteract this negative shock, FDI promotion in the RMG sector and a human-capital development program are considered. The former policy minimizes the negative impacts of the foreign labor market shock, while a combination of both policies is more equitable.     

基于对象—过程—主体分析方法的区域低碳交通评价研究

推动节能减排与促进低碳发展已经成为我国发展的重要议题,建立与低碳交通概念相适应的评价体系,对于我国低碳建设具有重要意义。运用对象—过程—主体分析方法,在对象维度考察能源消耗与碳排放;过程维度考察输入端、循环端和输出端;主体维度考察政府、交通企业和公众的共同行为。由此构建"对象—过程"维度和"对象—主体"维度2个一级指标13个子指标的区域低碳交通评价指标体系。在此基础上,结合模糊数学方法与理想解法,建立区域低碳交通评价方法。以江苏2017年交通发展为例开展评价分析,形成区域低碳交通政策矩阵,以期为低碳交通管理提供参考。     

Big Players in Slovenia

The subjectivism of Austrian economics helps to explain the statistical fact of long memory in asset prices. The theory of Big Players is an Austrian approach to understanding the effects of discretionary policymaking in markets. It leads to implications that can be tested with statistics. In particular, Big Players induce herding and, thereby, an increase of persistence in asset prices. A recent episode in Slovenian monetary theory provides a case study. This case study adds to a set of similar studies, all tending to support the theory of Big Players.     

A gramscian perspective on field dynamics. The case of the privatization of Italian steel industry

Institutional fields are not static, they undergo times of fragmentation and times of settlement. Neo-institutional research has long explained the settlement of fields as either the effect of political manoeuvring of actors, or of discursive activity influencing cultural codes, narratives and symbols. But can these processes really be considered in isolation? In this paper, we propose to adopt a comprehensive view on fields’ dynamics, one that embraces the interaction of political and discursive manoeuvring to explain how fragmented fields manage to settle. To do so, we build on the Gramscian concept of hegemonic practices as discursive and political processes that integrate cultural equivalence among actors with political alliances based on aligned interests. Hegemonic practices align actors in a new historical bloc (a new settlement). Through this lens, we interpret the case of the Italian State steel privatization (1984–1995) and propose a process model explaining what yields fields’ dynamics from fragmentation to settlement. The model highlights the action of diffused agency in field dynamics, thus overcoming the obsolete challenger/incumbent view, and the need of becoming a historical bloc for alliances to stabilize a field.     

后金融危机时代股票超额收益率影响因素的探索

运用判别分析法和决策树模型对上证180的成分股是否可以获得超额收益率及其影响因素进行了分析,并将两种方法的分析结果进行了对比。结果表明：两种方法都可以对上市公司是否可以获得超额收益进行分辨,并且可以找出影响因素。但是从两种模型的结果来看,决策树模型要明显优于判别分析法。从我们的分析样本来看,对企业是否可以获得超额收益率的影响因素主要有：市盈率、市净率、息税折旧摊销前利润/营业总收入等。在实际中,通过这两种方法,投资者可以寻找出那些具有超额收益率的股票进行投资,从而使得自身的投资结果优于大盘。     

Public and private healthcare services: What drives the choice?

This paper has explored patients' propensity to consume private healthcare services. We based our analysis on the typical tangible and intangible (for instance, responsiveness, reliability, assurance and staff empathy) domains of the SERVQUAL and SERVPERF methods. These variables may influence patients' decision-making when they choose between the public and private sectors. We combined factor analysis (to obtain a set of latent factors related to perceived quality) and a partial proportional ordered logit model to estimate the probability that a patient would access private healthcare services. To test the main hypotheses, we used data from a stratified sample in Sardinia, a peripheral region of Italy. Findings revealed that private and public healthcare are substitutes, especially for primary/specialised services. Patients who used public healthcare frequently and had a low income were unlikely to change to private healthcare or to recommend private services. ‘Responsiveness’ and perceptions on ‘tangibles’ were key in determining the probability that a patient would choose and recommend private services. This paper offers a multifaceted framework that can be used in future research to generalise these findings, especially in insular regions that are constrained by mobility.     

东莞市环境经济系统的能值分析

以能值理论与方法为基础,采用不同的能值指标和系统可持续性的综合性指标对东莞市的环境及经济发展状况进行分析,并与其他国家和地区相应指标进行比较,评价东莞市城市生态系统自然环境和社会经济可持续发展的状况。结果表明,东莞市全年利用总能值比较丰富,但经济发展程度与发达国家和地区相比还有一定差距,经济发展主要依赖外界的支持;东莞市自身环境资源相对匮乏,环境压力较大,远远超过了系统的环境承载力,东莞市可持续发展水平较低。结合东莞市实际,从能值分析角度提出其实施可持续发展的对策建议。
