Network analysis of the Caucasus’ image

Destination image is influenced by many factors, including destination promotion materials, the mass media as a general familiarity agent, the perceivers’ own characteristics and even researchers’ methodological choices. To isolate and minimize the impact of research on destination image, different qualitative and quantitative designs and analysis techniques have been utilized. However, no previous study utilized the network analysis technique, which may be useful to reveal a picture of destination image with the interconnections and hidden dynamisms of dimensions as well as its correlates. The present study applies this technique on qualitative data from an online sample of Americans on their perceptions of a relatively remote and unfamiliar destination, the Caucasus region, in order to hone in on the dramatic impact of mass media on destination image. Results revealed networks of meanings with residue of mass media messages about Boston bombing, with some differences among different genders and education levels.

旅游景观模糊美学特征包括形态模糊和内涵模糊.旅游景观模糊美学的成因机制主要是构成旅游景观的物质形态、物质结构和动态变化引起的时空跨越和质的飞跃,具有明显的边际效应,显示出量子化特征.旅游景观模糊美学在旅游景观欣赏和旅游资源开发以及旅游景观构建中具有重要的应用价值.     

女性劳动力市场理论研究——明塞尔《劳动供给研究》一书述评

明塞尔的主要思想在两卷本的《雅各布.明塞尔论文集》中得到了充分体现。他的论著之一《人力资本》系统地发展了人力资本的理论基础与分析方法;另一部《劳动供给研究》则促进了现代劳动经济学研究体系和专业风格的形成。其中《劳动供给研究》一书对人力资本理论研究中的劳动力供给问题,尤其是妇女劳动力供给行为作了详细的讨论与分析。本文主要以此书为基础,着重于讨论女性劳动力供给理论和工资差别理论,最后联系我国女性劳动力的实际情况,提出该理论的现实意义。     

Market Integration of Fish in Europe

This paper examines market integration between fish species in Europe, taking international market integration into account. Based on Juselius (2006) , market integration is found both on the fresh and frozen markets. The Law of One Price is in force on the fresh market within the segments of flatfish and pelagic fish. Assuming transitivity, a loose form of market integration is identified between 13 fresh and seven frozen fish species, and the relative prices are found fairly stable. The policy implication is that catch limitation measures implemented through the Common Fisheries Policy have limited and conditional effects on prices, because of the large size of the market and varying market integration. Therefore, many fishermen are not ‘compensated’ by price increases as a result of catch limitation measures.     

非洲猪瘟疫情对我国肉类价格影响的区域异质性研究

[目的]非洲猪瘟疫情暴发导致猪肉等畜产品市场供需结构性、区域性失衡,进而导致肉类价格大幅波动,不利于畜牧业高质量可持续发展。[方法]文章通过构建覆盖全国30个省（市、区,不含港澳台、西藏）,包括猪牛羊和白条鸡四大肉类价格和非洲猪瘟疫情指数的动态面板数据,运用面板向量自回归模型（PVAR）,研究非洲猪瘟疫情对猪肉等主要肉类价格的冲击和影响在重点、约束、适度发展区和潜力增长区(1)的区域异质性。[结果]（1）非洲猪瘟疫情对不同区域不同肉类价格的影响存在着正负向不趋同的方向性差异,在冲击程度大小和时滞期上均存区域异质性;（2）区域间和区域内不同省份间猪肉等肉类生产流通和供需形势、及非洲猪瘟发生发展程度的差异是非洲猪瘟疫情对这些肉类价格冲击影响异质性产生的主要原因。[结论]非洲猪瘟疫情对肉类价格影响存在较为明显的区域异质性,亟需进一步优化生猪等畜牧产业布局,加快形成区域协同发展格局;健全动物疫病防控体系,建立多方协同联动机制;完善市场风险预警调控机制,加快实现产需顺畅匹配,确保畜产品市场总体平稳运行和畜牧业健康可持续发展。     

辽宁省县域经济发展的地域差异及成因

运用主成分分析及聚类分析的数理统计方法,选择10项指标,对辽宁省44个县市经济发展水平的地域差异进行了综合评价和聚类划分。主成分分析结果表明:辽宁省44个县市经济发展水平存在明显的地域差异,其影响因素可概括为工业发展及综合经济实力因素、人均经济水平因素、社会稳定因素3个层面,累积贡献率达84.8%。聚类分析的结果表明:辽宁省44个县市可划分为发达地区、较发达地区、中等发达区、初等发达区和欠发达区5种地域类型;在此基础上,分析了44个县市经济发展的地域差异原因,同时提出了协调区域经济平衡发展的相应对策。     

Localizing Land Governance,Strengthening the State: Decentralization and Land Tenure Security in Uganda

Decentralization of land governance is expected to significantly improve land tenure security of small‐scale farmers in Africa, through ensuring better protection of their assets and reducing land‐related conflicts. This paper, however, cautions not to have too high expectations of transferring responsibilities for land administration and dispute resolution to local government bodies. Field research in Mbarara District in south‐western Uganda brings out how decentralization has limited impacts in terms of localizing land services provision. Nonetheless, local land governance has transformed in important ways, as decentralization adds to institutional multiplicity, and fuels competition among state and non‐state authorities, and about the rules they apply. Rather than strengthening local mechanisms for securing tenure, the reforms introduce new forms of tenure insecurity, fail to transform local conventions of dealing with land disputes and delegitimize local mechanisms for securing tenure. In practice, decentralization has had limited effects in securing tenure for the rural poor, yet reinforces the presence of the state at the local level in diverse ways.

中国行业收入不平等问题的解析

进入新世纪以来,中国行业收入不平等有持续扩大的趋势。基于回归方程的Shap-ley分解结果表明,人力资本、所有制、资本投资、技术等因素对行业收入差距有显著影响,其中人力资本对行业收入差距的贡献约为45%,所有制的贡献在20%以上。因此在治理措施上,实施教育均等化,提高教育回报率,开放垄断行业的劳动力市场,推行劳资谈判制度可以有效缓解行业收入差距持续扩大的问题。     

我国区域资本形成差异实证分析

在总结分析区域资本形成差异相关研究的基础上,利用泰尔指数对我国区域内、区域间和区域总体资本形成差异进行实证研究.分析结果显示:区域内资本形成差距不具备收敛特征,区域间资本形成差异具有日趋缩小趋势,区域总体资本形成差异与区域间资本形成差异表现出高度的吻合性.要加快中西部地区发展的步伐,提高资本利用效率,建立区域内部协调发展机制,以缩小我国当前区域资本形成的差距.
