试析饮食文化在旅游开发过程中的文化变异问题——发展多层次饮食文化旅游

中国在世界上享有"食在中国"的盛誉,拥有开发饮食文化旅游的特殊优势。然而从目前饮食文化旅游的发展状况来看,仍然存在着不少问题。随着旅游活动的逐步扩展,传统饮食文化受到旅游开发的影响而发生文化变异是不容忽视的重要问题之一。这就要求我们在进行饮食文化旅游开发的过程中要正确认识文化变异及其机制,并在此基础之上发展多层次饮食文化旅游。     

Factor allocation,economic growth and unbalanced regional development in China

On the basis of development accounting techniques and a factor misallocation framework, we use panel data of 30 Chinese provinces from 2000 to 2013 to assess how factor allocation affects economic growth and unbalanced regional development in China. In particular, we decompose economic growth into three parts, namely sector productivity (SP ), factor market efficiency (FME ) and factor endowment (FE ). We then conduct counterfactual analyses to investigate the short and long‐run roles of factor allocation in the income distribution across provinces. The results show that SP , FME and FE can explain 23%, 8.5% and 68.5% of economic growth, while labour, capital and energy reallocation account for aggregate productivity growth of about 47%, −4.8% and −0.1%. Furthermore, when the factors are efficiently allocated, transferring labour (capital, energy) from agriculture (service, industry) to the other sectors will increase the income per capita by 29.5% and 42.5% in the short and long term. Meanwhile, efficient factor allocation accounts for 32% and 29.7% of aggregate productivity and reduces the income variation across provinces by 25.5% and 23% in the short and long run, respectively.     

Video mining: Measuring visual information using automatic methods

Marketers are becoming increasingly reliant on videos to market their products and services. However, there is no standard set of measures of visual information that can be applied to large datasets. This paper proposes two standard measures that can be automatically obtained from videos: visual variation and video content. The paper tests the measures on crowdfunding videos from a leading online crowdfunding website, and shows that the proposed measures have explanatory power on the funding outcomes of the projects. These measures can be effectively implemented and used for large datasets. Further, researchers can apply these measures to other sets of visual information, and marketers could use the research to guide their video design and improve their video marketing effectiveness.     

广东省土地利用变化时空分异及其与城市化和工业化的耦合关系

研究目的:分析广东省1996—2008年土地利用变化趋势和特征,划分快速型、中速型、慢速型和稳定型4种土地利用变化类型,探讨土地利用变化与城市化和工业化耦合关系。研究方法:GIS技术,统计分析与耦合分析方法。研究结果:珠江三角洲地区土地利用变化剧烈,粤东地区次之,粤西地区和北部山区相对稳定;城市化、产业非农化与综合土地利用动态度有较高一致性,表现出良好的正相关性。土地利用变化越剧烈的地区,其城市化进程和工业化进程对土地利用变化的影响越大;处于城市化加速和完成阶段、工业化中期和后期的县市区土地利用变化剧烈。研究结论:城市化和工业化的迅速发展是导致土地利用变化的重要因素,必须通过掌握广东省土地利用变化的时空分异及其与城市化、工业化耦合关系,合理调控未来各区域土地利用发展方向。     

人力资本促进中部地区旅游经济的时空差异研究

人力资本创新是助力旅游经济高效发展的重要途径。以中部6省为研究单元,基于2009—2017年面板数据,综合运用变异系数、泰尔指数、σ系数及面板回归模型,探析中部地区旅游经济时空演化特征及人力资本对中部地区旅游经济的影响效应差异。结果表明：研究期内,总体来看,中部地区旅游经济发展水平呈稳步上升态势,由2009年的0.181增长到2017年的1.081,分省份来看,大致呈“山西>江西>湖北>安徽>湖南>河南”的空间分布格局;从区域发展差异来看,中部地区旅游经济发展水平的相对差异与绝对差异均不断扩大,呈不均衡、不协调的演化特征;人力资本对中部地区旅游经济发展水平的影响总体呈先抑制后促进的“U”型关系,呈现出明显的空间异质性。

The Effect of Board Characteristics on a Firm＇s Strategic Change

The purpose of this study is to identify the relationship between the characteristics of the board of directors and strategic change of a firm in the Chinese context. In this study, strategic change is defined as strategic deviation relative to industry norms and strategic variation relative to historical experiences. The size, independence and leadership structure of the board of directors are defined as the board characteristics. We then propose hypotheses on the effects of board characteristics on a firm＇s strategic change. This study takes strategic resource allocation profile as measure to calculate strategic deviation and strategic variation, and then empirically tests and verifies the hypotheses using data from Chinese publicly listed companies in the information technology industry from the year 2006 to 2010. We find that the size, independence and leadership structure of the board of directors significantly affect both strategic deviation and strategic variation. Therefore, we conclude that board characteristic affects a firm＇s strategic change. The conclusion of the study indicates that moderate reductions in the size of the board, increasing the proportion of independent directors and separating the roles of chairman and chief executive officer can facilitate promoting the process of strategic change for a firm in a dynamic environment. Through this study we re-examine the role and significance of the board of directors in strategic decision-making for a firm, and provide useful suggestions on how to form a board that can meet the needs for strategic change for a firm in a dynamic business environment.
