区块链技术在旅游业中的应用价值与场景探析

目前,随着大众旅游需求的不断升级,“到此一游”的踩点式旅游模式已经逐渐变得不再风行,体现旅游者兴趣差异化的品质旅游比重正在提升。在“互联网+”发展背景下,区块链技术具有透明度高、数据可溯源、不可篡改、可追踪性等众多卓越优点,可对旅游业中无法提供差异化供给、商家信用低、价格不明确、旅客维权难、基础设施管理差等困局逐一突破,推动旅游业向智慧化、透明化方向发展,对营造一个信用良好、发展健康的旅游交易市场氛围颇有裨益。论文简要介绍了区块链的基本原理,剖析区块链在旅游业的应用场景,从而讨论区块链+旅游的实际意义,为未来相关的研究提供借鉴。     

营商环境优化能够提升全球价值链分工地位吗*

本文基于世界银行发布的历年营商环境报告相关数据，从OECD ICIO提供的基础数据测算结果的基本事实出发，理论阐释了营商环境对攀升全球价值链的影响及可能机制。以此为理论先导，进一步利用跨国面板数据的计量检验发现：第一，营商环境优化的确对价值链分工地位具有显著正向作用；第二，上述正向作用不仅来自营商环境优化直接效应，而且还通过价值链迁移、创新活动激发、贸易条件改善等中介作用形成间接效应。据此，打造国际一流营商环境对促进中国攀升全球价值链具有重要支撑作用。     

旅游产业与农村可持续生计耦合的空间格局及驱动机制——以张家界为例

通过构建乡村旅游与农村可持续生计系统指标体系,运用变异系数和耦合协调度模型对2005—2018年张家界乡村旅游与农村可持续生计的耦合度和协调度进行测算,分析耦合协调度的空间格局,并运用地理探测器方法对其驱动机制进行分析。研究表明:①2005—2018年耦合协调度保持连续上升的趋势;②乡村旅游发展初期呈现东部高西部低的分布格局,中期呈现东南部滞后于西部的分布格局,但最终张家界整个区县达到优质协调;③耦合协调度空间分异的主要影响因素有人均GDP、旅游收入占GDP比重、农业机械化水平和人均财政收入等,且具有明显的时间异质性特征。

Why Do Politicians Intervene in Accounting Regulation? The Role of Ideology and Special Interests

Politicians frequently intervene in the regulation of financial accounting. Evidence from the accounting literature shows that regulatory capture by special interests helps explain these interventions. However, many accounting rules have broad economic or social consequences, such as their effects on income distribution or private sector subsidies. The perception of these consequences varies with a politician's ideology. Therefore, if accounting rules produce those consequences, ideology plausibly spills over and explains a politician's stance on the technical accounting issue, beyond special interest pressure. We use two prominent U.S. political debates about fair value accounting and the expensing of employee stock options to disentangle the role of ideology from special interest pressure. In both debates, ideology explains politicians’ involvement at exactly those points when the debate focuses on the economic consequences of accounting regulation (i.e., bank bailouts and top management compensation). Once the debates focus on more technical issues, connections to special interests remain the dominant force.     

Official Demand for U.S. Debt: Implications for U.S. Real Rates

We estimate a structural term-structure model of U.S. real rates, where arbitrageurs accommodate demand pressures exerted by domestic and foreign official investors. Official demand affects rates by altering the aggregate price of duration risk, and thereby bond risk premiums. Although foreign central banks' demand contributed to reduce long-term real rates mainly in the years prior to the global-financial crisis, the Federal Reserve's demand lowered rates during the quantitative easing period. Overall, the two-factor model, augmented to account for changing liquidity conditions, offers a good representation of real rates during the 2001–16 period; however, we flag some caveats and possible extensions.     

Marx 200: The Abiding Relevance of the Labour Theory of Value

ABSTRACT

Marxist political economy is alive and well, and not just because of the habitual turn to Marx in response to any crisis of capitalism. Both through Capital and through the continuing evolution of Marxism, Marxist political economy offers valuable insights that can illuminate the modalities of social and economic reproduction and the relationships between (different aspects of) the economic and the non-economic. Marxism’s presence has been felt through its own internal debates and debates with other approaches to political economy, and even through its influence on those reacting against Marxism. The key to the continuing relevance and analytical strengths of Marxist political economy lies in its capacity to provide a framework of analysis for unifying disparate insights into and critiques of the contradictions of capitalism across the social sciences. The instrument for forging that unity is Marx’s theory of value, the potential of which is examined and illustrated with reference to the Sraffian critique and two key concepts in Marxian political economy: the value of labour power and financialisation. They are explored in the light of the processes of commodification, commodity form and commodity calculation.     

分散决策下的双渠道供应链补偿策略——基于消费者渠道选择行为

为了有效解决由于对消费者的争夺从而引发的渠道之间关于定价、服务水平、利润等方面的冲突,基于消费者渠道选择行为,构建了网络直销市场与传统零售市场需求模型和双渠道供应链利润模型,运用Stackelberg模型,在制造商与零售商实施分决策时,通过制造商对零售商实施补偿激励前后的对比,分析了消费者渠道选择行为对网络直销渠道和传统零售渠道定价、制造商与零售商利润以及供应链总利润的影响,并求得最优定价及制造商的最优补偿额度和零售商的最优销售努力水平,进行了不同情况下的双渠道供应链利润的比较分析。结果表明,无论制造商是否实施补偿激励,都应随着网络消费者比例的增加而增加其网络直销价格;零售商的零售渠道价格应根据网络消费者比例的增加先降低到一定水平后再提升。当更多的消费者选择网络直销渠道时,制造商的补偿激励水平和零售商的销售努力程度均会下降。制造商应提高其补偿水平,进而激发零售商提高销售的努力水平,并使双方利润及供应链总利润最大化。研究结果为基于消费者选择行为的供应链补偿研究提供了新方法,对双渠道的供应链补偿研究有借鉴意义。     

新疆坎儿井农业遗产资源保护与旅游开发利用

[目的]分析新疆坎儿井农业文化遗产资源的旅游效用,以期更好地指导当地旅游资源的开发利用工作,达到促进区域休闲农业可持续发展的目的。[方法]文章以新疆坎儿井农业文化遗产资源为例,分析其资源特征、资源保护及开发现状;采用AHP分析法分析坎儿井农业遗产资源旅游效用,基于上述分析并结合农业文化遗产旅游发展的需求,提出优化其农业遗产资源保护及开发的规划、模式及策略。[结果]坎儿井农业文化遗产资源中主体旅游资源坎儿井工程(B_1)、辅助旅游资源农业文化资源(B_2)、客源与市场特征(B_3)和外部因素特征(B_4)的权重分别是0.43、0.22、0.10和0.06。[结论]在比较其生态价值、环保价值、旅游价值的基础上,发现在稳固生态价值与环保价值的同时,挖掘新疆坎儿井的旅游价值是实现农业文化遗产有效保护的最佳途径;主体旅游资源坎儿井工程和辅助旅游资源农业文化资源为坎儿井农业遗产资源旅游带来良好的经济收益,而客源与市场特征和外部因素特征权重最低,说明这两个因素是导致旅游效益权重低的主要原因;农业遗产资源旅游的保护和开发两者互惠共赢,但必须建立在重视农业遗产资源的保护及其宣传保护的基础上。
