Is health care a necessity or a luxury? Evidence from urban China

This article uses a smooth transition regression (STR) model to research the income elasticity of the health care expenditure of China’s urban residents in the 1990–2013 period. The results demonstrate that if the real income of China’s urban residents that lags a period is taken as a transition variable, urban residents’ health expenditure follows an LSTR1 nonlinear two-regime model. Here, the income elasticity of health care expenditure of China’s urban residents is 1.4919 in 1990–2002 and 1.2216 in 2003–2013. Overall, the income elasticity of health care of China’s urban residents is greater than 1, indicating that health care is a luxury.     

粮食安全与农业结构调整水平的协整分析*——以广东省为例

[目的]实现我国粮食安全与农业结构调整之间(即粮食增产和农民增收)关系的协调,较长时间以来是学界、政界关注的重要议题,但定量分析两者之间内在依存关系的研究一直欠缺。[方法]文章采用协整分析及Granger因果关系检验方法,以广东为例,对我国粮食安全(用粮食总产量来衡量)与农业结构调整水平之间的协整性及因果关系进行了研究。[结果]广东粮食总产量与反映农业结构调整水平的3个指标之间均存在长期均衡关系,且农作物播种面积中粮食作物面积对广东粮食总产量影响最大,每下降1%,粮食总产量下降0. 659 548%。短期内,反映农业结构调整水平的3个指标对广东粮食总产量的影响均存在波动,但由短期偏离拉向长期均衡的牵动作用均较弱。Granger因果关系检验表明农业在国民经济中的比重、农作物播种面积中粮食作物面积早期对广东粮食总产量产生单向影响,但影响程度相对较弱。[结论]提出应从农业结构调整以外的因素着手提高我国粮食安全水平,并通过调整农业区域结构去缓解我国粮食供求市场的结构性矛盾。     

茭簰考释--兼及江汉平原湖区人水关系

明清时期长江中游地区地方文献记载的茭簰,并非漂浮种植性质的葑田,而是漂浮居住性质的水上居家设施。“随波上下”且“不时迁移”是其基本特性,实质是借水之力以避水之害,乃湖区居民应对洪涝灾害的居住创举。茭簰不同于为众熟知的舟船,亦有别于水上航行的排筏,茭簰居民并非渔民,而是备有“种莳牲畜”的农民。茭簰与葑田,虽然一耕一居,却具有共同的指向。茭簰是湖区农家适应环境变化,根据生产生活需要而做出的相对选择,堪称湖区居民趋利避害、协调人水关系的代表性举措。     

中国自然保护地规划的回顾与对比研究

中国自然保护地历经60余年的发展，形成了多部门主导、保护类型多样的自然保护地体系。面对机构改革和以国家公园为主体的自然保护地体系建立的契机，传统规划的经验积累为新规划体系的构建提供了借鉴的可能。通过回溯机构改革前各类自然保护地规划，对比分析其规划结构体系，并从人地关系视角切入，分析各类规划针对保护对象、保护利用强度,以及社会发展调控上的差异，总结各类自然保护地规划的既有经验，为新时期规划体系的重构提供支撑。     

Opinion leadership vs. para-social relationship: Key factors in influencer marketing

The literature on influencer marketing has identified opinion leadership of influencers and parasocial relationship with influencers as two focal constructs affecting followers' purchase intention; yet they are only studied in isolation. This research aims to provide a comprehensive understanding of the effects of the two key constructs by combining and comparing them in a model with the moderators of post characteristics, namely post type and correspondent inference. Empirical results from 409 online followers of two Instagram accounts confirm the complementary effects of opinion leadership and parasocial relationship in influencer marketing and reveal the more prominent role of parasocial relationship over opinion leadership in affecting followers’ purchase intention. These effects are moderated by post characteristics. Storytelling posts intensify both effects. Correspondent inference enhances the effect of parasocial relationship, but not that of opinion leadership. These findings point to the importance of the social aspect of influencer marketing and inform the influencer marketing research and practice on “who says what” for improving communication effectiveness.     

Lifestyling entrepreneurs’ sociological expressionism

This study explores the tourism host-home relationship investigated through documentary analysis of photographs choreographed through mutual negotiation between hosts and researcher (collaborative auto-driving) and participants’ spoken narratives (photo-elicitation interviews); we identify the significance for tourism product construction. Major findings concern the sociological expressionism of the tourism lifestyle entrepreneur who creates a certain personal brand identity or ‘lifestyling’ through their commercial home presentation; ‘private’, ‘inclusive’ and ‘temporal’ classification categories of hosts’ favourite spaces in the home are identified, based upon the individual spatial management strategies employed. Depictions of favourite spaces emphasised emotional and sensorial dimensions rather than material things present, and were described as spaces of contentment and tranquillity essential for energising hosts in the ongoing production of the commercial home.     

The role of relationship quality in raising organizational change acceptance: The case of the Greek hotel industry

This study examines whether the quality of an employee's relationships, within the context of the hotel industry, has an influence on their behavioral intention towards organizational change. The researchers suggest that the quality of relationships is an important element of an individual's social capital and can be evaluated using five key dimensions: the extent to which relationships are tangible, responsive and reliable, as well as the extent to which they offer empathy and assurance. Furthermore, this research examines whether organizational commitment and job satisfaction have an effect on the association between relationship quality and an individual's behavioral intention towards organizational change. The data collected from a sample of 100 hotel employees in Thessaloniki, Greece, show that relationship quality has a positive association with an individual's behavioral intention towards change. Additional results highlight the roles of job satisfaction and organizational commitment as mediating variables. Managerial implications relevant to the findings and pathways for further research are also discussed.     

Incorporating textual information in customer churn prediction models based on a convolutional neural network

This study investigates the value added by incorporating textual data into customer churn prediction (CCP) models. It extends the previous literature by benchmarking convolutional neural networks (CNNs) against current best practices for analyzing textual data in CCP, and, using real life data from a European financial services provider, validates a framework that explains how textual data can be incorporated in a predictive model. First, the results confirm previous research showing that the inclusion of textual data in a CCP model improves its predictive performance. Second, CNNs outperform current best practices for text mining in CCP. Third, textual data are an important source of data for CCP, but unstructured textual data alone cannot create churn prediction models that are competitive with models that use traditional structured data. A calculation of the additional profit obtained from a customer retention campaign through the inclusion of textual information can be used by practitioners directly to help them make more informed decisions on whether to invest in text mining.     

The State as Both Regulator and Player: The Politics of Transfer of Development Rights in China

The conventional argument that the introduction of transfer of development rights (TDR) shifts the power of land use regulation from the state to the market is increasingly under challenge. In China, the state's grip on land is reinforced through TDR, in which the state is both regulator and player. This state-dominated form of TDR affects China in three ways. First, competing aspirations of different scales of government complicate how TDR is implemented. Although the central state promotes TDR to maintain a national balance of arable land, some local states instrumentalize it to expand their landed basis of accumulation. Secondly, TDR tends to benefit the state but not its people. It may increase the fiscal income of the sending government and lessen the land shortage of the receiving government, but sometimes at the expense of the interests of land users without land ownership. Thirdly, given the state's deep involvement in TDR programs, the key for China's TDR to protect arable land lies not so much in clear property rights or a fully fledged market as in effective checks and balances regarding the state's powers over TDR. These three observations attest to the embeddedness of TDR in the local political economy.
