Testing for structural breaks in panel varying coefficient models: with an application to OECD health expenditure

In this article, we propose a model selection approach for testing structural breaks in a semiparametric panel varying coefficient model. Monte Carlo evidence shows that the proposed model selection approach performs well in finite sample settings. Applying the method to an empirical data, we find evidence of structural breaks in Organisation for Economic Co-operation and Development (OECD) health expenditure data by allowing for income elasticity to be state (income)-dependent. The relationship between health expenditure and income is subject to two types of structural changes: smooth changes over income and structural breaks in the time dimension. The findings hold for both foreign exchange rate-converted and Purchasing Power Parity-converted expenditure and GDP.

Consumer Responses to Corporate Social Responsibility (CSR) in China

This research explores how consumers respond to Corporate Social Responsibility (CSR) in China with a multiproduct, comparative survey. Empirical results conclude that (1) Chinese consumers, who show a high level of awareness and trust of CSR, are more likely to transform a good CSR record into positive corporate evaluation, product association, and purchase intention; (2) Consumer responses to CSR vary across different product categories. Those firms selling experience products (vs. search and credence products) are more likely to gain consumers’ positive product associations and purchase support through CSR practices; and (3) The relationships between consumer demographics and their CSR responses are not linear, and those consumers with a middle level of age and income would respond to CSR more positively. Managerial implications are provided.     

Turbulence in growing and declining industries

Turbulence over the industry life cycle is examined for the case of Portugal using the lowest possible level of industry aggregation, thus allowing for the use of panel data to study the evolution of product markets. Replacement of exiting firms by subsequent entrants plays a primary role in generating turbulence in high growth markets, while displacement of incumbents by recent entrants is the main selection force in declining markets. As the industry life cycle progresses, trial-and-error entry and entry mistakes decrease, and turbulence subsides.     

中国城市土地集约利用与城市化协调发展评价研究

文章在构建城市土地集约利用与城市化协调发展评价模型的基础上,分析了中国31个省区城市土地集约利用与城市化协调发展的程度。研究结果表明:(1)中国省区协调度及协调发展度都存在着明显的区域差异,协调发展水平整体上表现出东部地区大部分省份高于中西部地区的规律,而且与区域经济发展水平具有较强的相关关系;(2)中国省区城市土地集约利用与城市化协调度及协调发展度在空间分布上具有一定的对应性;(3)按照协调度和协调发展度将31个省区分为八类,分别体现经济发展、自然条件和政策因素等对区域城市土地集约利用与城市化作用的差异。     

论英语俚语翻译策略

据统计,英语常用语中20%为俚语,如何准确实现英语俚语与汉语之间的转换成为目前翻译工作者越来越关注的问题。掌握科学的英语俚语翻译策略,必须全面了解英语俚语,包括俚语的由来、文化内涵以及俚语特征,并从直译、意译、阐释翻译、引申、还原和同步六种翻译方法入手,研究俚语翻译策略。     

城市给排水系统设计分析

城市规划是对城市整体建设与功能布局的规划与构想,直接关系到城市未来发展的方向与前景.给排水设计在城市规划中占有十分重要的地位和作用,对满足城市居民的基本生活与工农业生产的供水、排水系统建设具有很重要的意义.在城市整体规划中,市政相关部门要紧紧抓住给排水设计的重点和难点,并以其为根本出发点,力争制定出科学、合理的城市给排水设计方案,进一步促进城市的经济建设和未来发展.     

两岸三地服务业国际竞争力比较分析

国际上常用的服务业国际竞争力主要评价指标包括MS(国际市场占有率)、TC(净出口指数)、RCA(显示性比较优势指数)和CA(显示性竞争优势指数)。文章根据联合国贸发会议的基础数据,分别计算、比较了两岸三地服务业的MS、TC、RCA和CA四类指数,并且分行业计算了两岸三地的RCA指数,进而分析了两岸三地服务业各自存在的问题。结论认为:从四类指数的计算结果看,香港在两岸三地中国际竞争力最强;内地服务业尤其是生产性服务业相对比较落后。文章最后探讨了两岸三地服务业的未来合作前景。     

地方政府权力的空间伸展与统治基础的初步构建——以赣政十年(1932-1942)税收聚集为例

借用空间聚集的概念,以赣政十年江西的税收聚集情况为例,运用相应实证检验方法及面板数据的计量模型,证实江西地方政府运用税收聚集推进政权权力空间的伸展和实现经济、社会效率的产出,从而初步奠定了转型时期近代江西地方政权在乡村经济社会的统治基础,进而也为该地区近代文化网络的构建创造了条件.
