山西省A级景区旅游流网络特征研究

收集携程网站上发布的关于山西省A级景区的旅行游记，以社会网络分析法构建261个景区为节点的旅游流网络，并分析节点特征以及整体网络结构特征。结果表明，在山西省A级景区旅游流网络中，等级较高的景区其吸引力较强；平遥古城、五台山、悬空寺等景区在山西省旅游流网络中处于关键核心位置，但能发挥旅游路线的中转枢纽作用的A级景区数量较少；旅游流网络具有明显的核心－边缘特征，同时表现出较大的规模以及较小密度。

海运设施联通推动贸易畅通是促进“一带一路”高质量发展的重要途径。文章基于社会网络分析法，揭示了共建“一带一路”国家（地区）班轮航运网络的结构特征，并实证检验了其对沿线双边贸易的影响。研究发现：沿线班轮航运网络表现出“小世界”的特征；各国（地区）的个体特征存在明显的空间差异；一国（地区）节点强度和广延性的结构特征显著促进了双边贸易增长；网络结构特征的贸易增长效应在“一带一路”倡议实施前后、不同港口环境和不同经济发展水平下存在显著异质性；机制检验表明，网络结构特征将通过降低贸易成本和增强市场引力来促进双边贸易的增长。     

基于网络游记的新疆旅游流空间网络动态演化研究

本文以网络游记为研究样本,对新疆旅游流空间结构进行动态分析,用Ucinet导出路径图,利用社会网络分析法计算旅游流空间网络的中心性、结构洞和网络密度,实现旅游流空间网络结构的可视化。研究结果表明,新疆旅游流网络密度逐年增加,节点持续更新,但疏密不均问题较为严重;新疆旅游资源禀赋、交通通达度、旅游服务基础设施是影响旅游流结构演变的重要因素;随着时间轴向前推进,新疆旅游流网络空间结构演变呈现出结构趋于完整、节点关联耦合紧密的趋势。由此提出旅游主管部门应加强与景区景点联系,增强政府与旅游发展网络关系;提高旅游景区景点互动,加强资源共享;旅游企业与互联网相结合等对策,以实现新疆旅游流网络的均衡。     

建党百年文化视域下的新疆红色旅游融合研究

本文选取网络文本数据,以入选“建党百年红色旅游百条精品线路”的新疆21个景区为例,对比分析景区的红色旅游体验文本和红色文化传播文本,了解建党百年文化视域下新疆红色旅游和红色文化的融合发展情况。研究结果表明,在新疆红色旅游中,游客对红色文化载体的感知最为强烈,能够对红色文化产生一定认同感,红色旅游的教育功能较为显著;同时,游客在游览过程中的积极情绪有利于其产生幸福感。今后可进一步推动新疆“红色文化+”融合发展,借助现代科学技术提升红色文化融入度,加强红色文化产品创意设计和品牌打造,并借助营销不断扩大红色文化影响力,更好地传承红色文化,推动新疆红色旅游健康、快速发展。

我国区域创新能力的空间关联特征及其效应研究

强化区域联动、推进协同创新是提升创新能力及实现高质量发展的重要抓手。基于我国30个省(区、市)数据,采用空间自相关检验与社会网络分析法考察我国区域创新的空间关联特征,并进一步探究个体网络结构特征对创新能力的影响效应。研究表明,邻近视角区域创新能力空间分布呈“同质集聚”特征,多数地区处于低值集聚区且长期稳定;网络视角区域创新能力空间关联呈复杂网络形态,且网络联系愈发紧密,网络结构趋于稳定;江苏、上海、天津、浙江、北京、广东等居于网络核心,拥有较高的点度中心度、接近中心度及中介中心度;点度中心度、接近中心度均能显著促进区域创新能力提升,且点度中心度边际效应强于接近中心度,中介中心度表现为负向作用。据此,在推进区域协同创新进程中,应树立创新空间联动意识,强化核心地区创新辐射,精准制定创新发展政策,完善协同创新体系建设。

Taxing Times in Indonesia: The Challenge of Restoring Competitiveness and the Search for Fiscal Space

Indonesia’s economic growth picked up slightly in mid-2016 but remains below the level demanded by government and popular aspirations. Despite a plethora of reforms intended to increase efficiency and productivity, some policies are perverse and longstanding problems of implementation remain. The share of manufacturing has declined, the real exchange rate has appreciated, exports have dwindled, and growth has been trending downwards. The banking sector is stable but inefficient, with wide net interest margins and numerous barriers to competition. Trade protection, particularly in basic food commodities, has created high costs that weigh particularly heavily on the poor. Declining government revenues have placed increasing pressure on the public budget, even as the current administration aims to increase spending on infrastructure and welfare and to enhance productivity. In an effort to increase revenues, the government has announced a tax amnesty program and other measures. In addition, Sri Mulyani Indrawati, the new finance minister, has taken steps to cut non-essential expenditure in order to secure high spending on infrastructure and at the same time keep within the 3% budget deficit limit stipulated by law. Although the overall debt situation is not yet alarming, declining revenues and budget cuts that do not fully reflect this decline are putting pressure on increasing debt levels. The government’s high-profile tax amnesty program was the major policy initiative implemented in the second half of 2016 that aimed to relieve this pressure. Despite widespread criticism of, and scepticism about, the tax amnesty (both within and outside Indonesia), its first phase had a much higher participation rate than most independent accounts expected. Revenues raised so far through the amnesty are less than 60% of the official target, but this is actually a strong result for the short term. The bigger question, however, is whether the amnesty is a key element of a more encompassing strategy to overhaul the system of taxation and tax administration.

The causes of Japan's ‘lost decade’: The role of household consumption

In this paper, I analyze the causes of the prolonged slowdown of the Japanese economy in the 1990s and find that the stagnation of investment, especially private fixed investment, was the primary culprit. I then investigate the causes of the stagnation of household consumption during the 1990s and find that the stagnation of household disposable income, the decline in household wealth, and increased uncertainty about the future are among the contributing factors. Finally, I consider whether demand side factors or supply side factors were more important as causes of the prolonged slowdown of the Japanese economy in the 1990s and conclude that the former (especially misguided government policies) were probably more important.     

Stature growth in industrializing Argentina: The Buenos Aires industrial belt 1916-1950

A sustained long-term increase in average stature accompanied the process of import-substituting industrialization in the main suburban area of Argentina, the Buenos Aires Conurbano. This gain in net nutrition was attained before the rise to power of a re-distributionist political party: the Peronists. The article also provides evidence of a decline in average heights during the period 1939-1945, which challenges us to revise the traditional wisdom about the impact of World War II and Peronist social policies and its implications for the nutrition and health of children. The new evidence on heights shows also persistent social and regional differences over time that had not been documented before.     

The Transfer of Property Rights from the Public to the Private Sector in Hong Kong: A Critical Assessment

Abstract

The privatization idea may have lost some of its luster in recent years, but it remains relevant in today's socio-economic environment and is pursued consistently in industrialized and industrializing countries alike. Hong Kong has followed the general pattern in a manner reflecting its particular circumstances and its institutional modus operandi. The underlying logic may not appear highly compelling, from a short-term perspective, yet there are sound grounds for approaching the task positively, if viewed from a multi-year standpoint. Rather surprisingly, for such a quintessentially capitalist society, Hong Kong has not confronted the privatization challenge astutely on the political front and has handled it somewhat mechanically in managerial terms. The benefits to the community may have thus been more modest than one could legitimately expect, given the historical backdrop.     

Measuring performance: Ranking state success over two decades in India

This paper proposes new composite measures of relative and dynamic state performance to improve governance and delivery of public programs in developing countries with a federal structure. We illustrate the use of the indices to rank the performance of 19 major Indian states on two large development programs launched by the Indian government over the last two decades using publicly available data. Although we find volatility in performance over time, there exists a positive correlation between measures of initial (administrative) state capacity, development and accountability with program outcomes. Our findings have important implications for both the design and implementation of large-scale public programs across developing countries.     

Thinking regionally: Aviation and development implications in the Karoo region,South Africa

This study focuses on regional economic development in South Africa, across provincial political jurisdictions. The article argues that remote hinterlands can be more usefully understood as forming an integrated whole, rather than functioning as the poor rural cousins of their provincial metropoles. This article considers three propositions: that key transport projects (such as airports) may unlock regional development; that this may stimulate regional spatial integration; and that this may spur the South African government to address its weak regional planning system. All three propositions are speculative, drawn from the international literature, but they contribute to an argument for greater spatial coherence in South African planning in rural regions. The argument is illustrated with reference to the Karoo region of South Africa, and the potential of a new airport to impact on regional economic dynamics. Furthermore, the article argues that such impacts will require new regional planning systems, which are currently absent from the South African political system.
