云南省团队游空间结构及其聚散效应研究

在旅游业高质量快速发展的背景下,全面厘清与掌握省域尺度范围各旅游节点在网络中的角色和地位,并解析其网络结构效应具有重大意义。针对现有研究因旅游流数据采集限制而较少对团队游空间结构研究的不足,基于云南省旅游包车客运信息,运用社会网络结合空间分析的方法,提取了云南省团队游网络空间结构特征,并对其聚散效应进行分析。结果表明:云南省团队游整体网络密度较小且淡旺季表现出相似特征,网络对各节点的旅游联系与合作影响尚未显现,暴露出云南省团队游旅游市场发展的不均衡;团队游网络外向中心势显著高于内向中心势,网络空间集聚趋势明显;通常具有较强外向中心性的旅游节点同时也具有较强内向中心性,表现出“集中—发散”的聚散规律;旅游节点的聚散效应表现为单个节点以圈层状向外递减形式发生,其扩散路径主要集中于文山—蒙自、景洪—思茅方向。整体上,云南省区域旅游业发展差异明显,应重点加强滇西南与滇西旅游区、滇中与滇东北旅游区的旅游资源开发与合作。     

威客活动水平的区域空间统计分析——从人力资本视角看区域经济发展失衡

探索了威客活动的地域分布特征,并将之与区域经济发展水平相联系,构建了区域经济发展研究的新视角。通过绘制分位地图,探索了威客活动可能存在的地域歧视,从需求和供给的角度分析了威客活动的地域分布情况。利用空间统计分析方法对比了GDP与威客数量的地域分布情况。研究结果表明:威客活动中不存在明显的地域歧视;威客活动的需求和供给分布较为一致;大多数省份的威客数量水平低于其经济发展水平;威客的地域分布不存在明显的集聚现象。整体而言,以威客平台为基础的网上劳动力市场的存在与发展,借助互联网在联系不同地域、消除地域差异上起到了重要作用。     

House price determinants in Athens: a spatial econometric approach

In this paper, we try to identify the price determinants in the biggest real estate market of Greece, the metropolitan area of Athens. For that purpose, various spatial econometric models are used to explore their prediction ability and we are displaying the variations in property prices for the wider area of Athens. These models have been compared based on different criteria such as model fit, the Akaike information criterion and variance of the residuals. Our results indicate that, in our case, the spatial general model is the most appropriate simultaneous autoregressive model when dealing with spatially autocorrelated prices of housing properties data, in terms of our selection criteria.     

The Relationships Amongst Emotional Experience,Cognition, and Behavioural Intention in Battlefield Tourism

The objective of this study was to identify the hypothesized relationships amongst emotional experience, cognition, and behavioural intention in battlefield tourism. A face-to-face questionnaire survey was administered and 655 valid questionnaires were collected at heritage site related to the Sino-French War in Keelung, Taiwan. The results revealed significant positive relationships between emotional experience and cognition as well as between cognition and behavioural intention. Structural equation modelling verified that cognition fully mediated the effects of emotional experience on behavioural intention. Moreover, this study suggests that cognition may be an accurate predictor of behavioural intention, particularly in regard to battlefield tourism.     

“省直管县”财政体制如何促进经济增长——基于江苏省2004-2009年数据的实证分析

近几年来,"省直管县"财政体制在各省陆续实施,其主要目的在于克服既有的市管县体制存在的各种弊端。可以预期,这项改革措施有减少行政管理成本、解决县乡财政困难、促进县域经济增长等多种潜在作用。但可能存在的问题是,该财政体制如何促进经济增长?文章利用江苏省51个县(市)2004-2009年的空间面板数据进行分析发现,"省直管县"财政体制对经济增长的作用主要是通过县(市)扩权而产生的"政府竞争效应"实现的。     

Quantitative Analysis of Foreign Trade and Environmental Efficiency in China

This article analyzes the relationships among trade, the economy, and environmental quality in China. First, in the context of these relationships, the Super-SBM model is used to calculate the environmental efficiencies of thirty Chinese provinces and cities to obtain the degrees of regional disparity. Second, China’s provincial panel data from 2003 and 2012 are used to establish an influential factor indicator system of environmental efficiency. A section-weighted fixed effect model then provides insights about influential factors such as spatial heterogeneity. Third, the article establishes a variable coefficient model to identify the relationships among the objects of the study and divides the Chinese regions into four types. The suggestions include enhancing environmental and business regulations to ensure equilibrium between trade, the environment, and local economies.     

Raising the bar (4)

This editorial summarizes and comments on the papers published in issue 11(4) so as to raise the bar in applied spatial economic research and highlight new trends. The first paper deals with common factors and spatial dependence in the error term specification of a production function model. The second paper sets forth a New Economic Geography (NEG) model with production activities that vary in their complexity, so as to analyse the impact on specialization patterns across different regions. The third paper measures the efficiency of local public investments using a relatively unknown econometric technique in which the time span over which the variables in the regression equation are measured is increased by one time period every run. The fourth paper adopts a conditional quantile regression approach to determine the impact of people employed in informal jobs on the wage distribution in Colombia and five of its regions. Finally, the last paper proposes and tests two new Bayesian variable selection approaches for spatial econometric models.     

基于主客观组合群决策的权重区间确定方法

提出了一种确定权重区间的方法,即将由多位专家确定的主观权重和用多种方法计算的客观权重相结合,形成权重区间,通过分析主客观权重区间的重合关系,计算权重区间的置信度和精确度,据此对权重区间进行循环优化。最后用算例表明了该方法的科学性和可操作性。     

Regulations for the Eighth International Congress of Actuaries

Abstract

The present paper proposes and investigates a procedure for numerical evaluation of the transition probabilities for a time-inhomogeneous Markov process when the intensities are known (estimated). The procedure is based on Taylor-expansion of the transition probabilities linked with the Chapman-Kolmogorov equations.
