Preferences for tourist information centres in the ubiquitous information environment

The rapid development of information communication technology has encouraged tourism authorities to carefully consider the typical duties of tourist information centres (TICs), wherein visitors acquire various kinds of travel information about a particular destination. This study aims to provide useful management implications to help tourism organisations develop feasible TIC operational strategies and implement alternative services in the ubiquitous information environment. To provide a richer understanding of tourists' heterogeneous preferences for TICs, this study makes use of the stated preference choice method with a sample of South Korean domestic tourists. Despite the widespread use of personal mobile devices, our study results suggest that South Korean domestic tourists still prefer to visit various types of TICs to acquire travel information. Results indicate that the TIC visitor group is less sensitive than the non-visitor group to advanced information communication technology and more satisfied with the availability of WIFI signals to facilitate the use of personal mobile devices or laptops. Our respondents also demonstrate their preferences for some TICs constructed with container structures, whereas they showed a strong aversion to visiting booth-styled TICs inside larger buildings. Based on these findings, this study provides several management strategies to fulfil tourists' ever-changing needs.     

Labour market impacts of occupational licensing and delicensing: New evidence from China

We examined the recent occupational regulation changes in China and their labour market impacts. Using data from the China Labor-Force Dynamic Survey from 2014 to 2018, we found an earning premium of approximately 10 per cent, as well as more employment-based benefits, for those with an occupational license compared to those without one. Licensed workers reported higher skill-job task match than unlicensed workers. Our data cover the period of occupational regulation reform in China, when 70 per cent of occupations previously licensed or certified were deregulated. Over this period, the licensing status remained associated with positive earning and employment benefits premiums, and better skill-job task match at the labour market level. However, delicensing led to a distributional shift in the earning dispersion, especially at the bottom of the earning distribution; earning premiums rose sharply for the 10th to 30th percentiles. Workers directly affected by the licensing reform reported a significant decrease in employment benefits and in subjective job quality measures (i.e. skill-job task match and voice at work) after delicensing, relative to never-licensed workers. We suggest that non-wage compensation is lost in the short term because the signal of competency is no longer valued by employers after delicensing.     

中国城镇化和水资源利用的协调性分析*——基于熵变方程法和状态协调度函数

［目的］通过研究2007—2016年城镇化和水资源利用的协调性,为两者协调发展提供政策建议。［方法］利用熵变方程法和状态协调度函数实证分析。［结果］(1)基于熵变方程法得到的相对协调度结果与利用状态协调度函数测算的静态协调度结果基本一致,目前我国城镇化与水资源利用逼近或处于协调发展状态,但在2009—2011年两者动态协调度偏离了协调发展轨迹。(2)3类城市中地级以上城市城镇化与水资源利用目前处于协调发展状态,两者动态协调度一直处于协调发展的轨迹上,地级市和县级市城镇化与水资源利用则处于基本协调状态,尚未达到协调状态,即目前城镇化发展的同时,水资源利用情况出现了小幅恶化,且2类城市动态协调度分别在2009—2012年和2009—2011年偏离了协调发展轨迹。［结论］我国尤其是地级市和县级市需要统筹城镇化发展与水资源利用,既需提升城镇化质量,又需进一步贯彻执行水资源管理法规,捋顺其管理体制,完善水资源价格形成机制以及污水处理收费制度,构建多渠道的水资源循环利用机制,达到城镇化进程中水资源可持续利用。     

中国马铃薯生产区域布局的时空特征与驱动机制研究*——基于主产区的面板数据的分析

[目的]基于1993—2015年中国马铃薯21个省区的数据,实证研究马铃薯生产区域布局的时空特征及其内在的驱动机制。[方法]从全国和5个马铃薯优势产区层面,运用生产规模指数分析马铃薯生产区域布局的时空特征,从自然环境、技术进步、经济效益、非农产业化水平、政府支持政策等方面厘清和探究马铃薯生产区域布局的驱动机制,并重点利用面板数据计量模型研究这些因素在全国以及5个马铃薯优势产区的影响的差异性和重要程度。[结果]中国马铃薯播种面积从1993年的308. 720万hm2增至2015年的551. 830万hm2,呈现迅速增长、下降与增长交替并存、平稳增长3个阶段;中国马铃薯生产的地理集聚现象明显。一方面,马铃薯生产规模在不同省区出现更迭变动。另一方面,马铃薯生产区域进一步向优势区域集中,呈现出向西南和西北优势产区集中的特征。[结论]中国马铃薯生产区域布局是自然灾害、农业基础设施、技术进步、马铃薯与粮食生产净利润比值、非农产业水平和政府支持政策等因素共同作用的结果,其中自然灾害、农业基础设施、非农产业化水平、政府支持政策的影响更为显著,但由于区域差异,各因素在全国和不同马铃薯优势产区的影响程度有明显的差异性。

Adjusted Pearson Chi-Square feature screening for multi-classification with ultrahigh dimensional data

Huang et al. (J Bus Econ Stat 32:237–244, 2014) first proposed a Pearson Chi-Square based feature screening procedure tailored to multi-classification problem with ultrahigh dimensional categorical covariates, which is a common problem in practice but has seldom been discussed in the literature. However, their work establishes the sure screening property only in a limited setting. Moreover, the p value based adjustments when the number of categories involved by each covariate is different do not work well in several practical situations. In this paper, we propose an adjusted Pearson Chi-Square feature screening procedure and a modified method for tuning parameter selection. Theoretically, we establish the sure screening property of the proposed method in general settings. Empirically, the proposed method is more successful than Pearson Chi-Square feature screening in handling non-equal numbers of covariate categories in finite samples. Results of three simulation studies and one real data analysis are presented. Our work together with Huang et al. (J Bus Econ Stat 32:237–244, 2014) establishes a solid theoretical foundation and empirical evidence for the family of Pearson Chi-Square based feature screening methods.     

股票杠杆交易行为及收益分析——基于融资融券交易数据

作为重要金融工具,股票杠杆交易对于资本市场效率的提高具有重要意义.本文通过融资融券的交易数据研究中国股票杠杆交易行为及收益情况,从信息披露、盈余质量及公司估值三个层面,本文发现参与融资融券的杠杆交易者更多选择信息披露质量差、盈余质量低的公司,且交易的股票估值偏高.通过构建投资组合,我们发现这种杠杆交易行为获得超额收益.本文进一步从业绩预告和证监会处罚两个视角进行检验,发现杠杆交易者可能是通过内幕信息获得收益.本文打开杠杆交易的黑箱,为监管层监管杠杆交易的合理性和必要性提供了依据,也为在打造规范、透明、有活力的资本市场过程中,如何让金融工具更好地服务于资本市场提供了参考.     

基于DEA模型的青岛市休闲农业效率评价*——以青岛市休闲农业与乡村旅游示范点为例

[目的]以青岛市休闲农业为研究对象,分析青岛市休闲农业运行效率,为推动青岛市休闲农业发展提供建议。[方法]以青岛市15个休闲农业与乡村旅游示范点的调研数据为基础,构建了青岛市休闲农业效率评价指标体系,运用数据包络分析方法对青岛市休闲农业效率进行评价。[结果]青岛市休闲农业的综合效率相对较低,综合效率平均值为0. 577,仅达到最优水平的57. 7%,15个示范点中只有5个示范点的综合效率达到DEA有效。青岛市休闲农业的纯技术效率不高,纯技术效率平均值为0. 713,有8个示范点的纯技术效率未达到最优。青岛市休闲农业的规模效率一般,规模效率平均值为0. 774,规模报酬不变的示范点有6个,数量最多。在15个休闲农业示范点中,有8个示范点存在土地和劳动力投入冗余问题。[结论]青岛市休闲农业综合效率与纯技术效率较低;规模效率一般,大部分示范点处于规模报酬不变阶段;投入冗余问题突出。     

县域农村居民点空间重构研究进展

[目的]通过对我国县域农村居民点空间重构相关研究进展进行综述,剖析当前研究中可能存在的不足,探讨该研究领域未来可能的发展方向,以期丰富我国县域农村居民点空间重构的理论与实证研究。[方法]文章采用文献回顾及归纳分析法,从县域农村居民点空间分布及其演变特征、农村居民点空间重构思路与方法、农村居民点空间重构模式与策略等三方面对该领域的研究进行综述与讨论。[结果]当前我国县域农村居民点空间重构研究内容不断丰富,但由于农村居民点空间重构是一个涉及自然、社会和经济等多方面的复杂系统,县域层面相关研究还不成体系;不同地貌类型县域农村居民点空间重构对比研究不足,对"三块地"改革、精准扶贫、乡村振兴等社会经济转型背景下的农村居民点空间重构模式与策略研究仍有欠缺,研究结果之间也相对独立,缺乏整合集成。[结论]今后应加强不同区域县域农村居民点空间重构研究的对比分析,探索不同发展阶段和背景下的县域农村居民点空间重构模式与策略,开展跨学科、多元化的综合性研究是该领域未来的发展趋势。     

Experiential learning and its effectiveness from the perceptions of hospitality students

This work aims to review the implementation situation of experiential learning (EL) in China’s hospitality education and explore the perceptions of students on the effectiveness of the adopted EL methods. Observations and focus group discussions are conducted in three vocational colleges and three universities in China. The study reveals that EL activities are widely utilized in China’s hospitality education. Generally, students state that EL is more effective than traditional classroom learning. Nonetheless, they consider some EL activities as being ineffectively implemented. Several suggestions are given in this paper to provide support to hospitality educators for improving the utilization of EL methods and facilitate student learning. Furthermore, unique EL methods that are not documented in literature are adopted in China’s hospitality education.
