关天经济区新型城镇化水平综合评价——基于PCA分析法

首先在界定了新型城镇化内涵的基础上,从新型城镇化发展的动力系统、质量系统和公平系统三大方面构建了评价关天经济区新型城镇化水平的指标体系,然后采用PCA主成分分析法对关天经济区各市区2003—2012年新型城镇化综合水平进行了测定及排名。结果显示:经济区在10年间新型城镇化水平总体呈上升趋势,但仍存在基础设施落后、城乡居民收入差距过大、产业结构不合理等问题。因此,以强化城镇发展动力提升为目的,合理配置产业结构;以提升城镇质量为核心,加强城镇基础设施建设;以改善社会公平为着力点,缩小城乡收入差距成为应对关天经济区新型城镇化问题的必然选择。     

秦汉焚尸非火葬刍议

秦汉史籍所记载的焚尸,并非传统意义上的火葬。这些焚尸的目的大多是对死者的一种羞辱和对生者的一种泄愤。与传统意义上的焚尸相比,不仅目的不同,而且主持焚尸者大多为死者的仇敌或敌人。焚尸过程充满暴力,缺乏火葬所必须的仪式。这种掘人祖坟、焚尸的行为与当时的社会伦理相背离,也与当时的丧葬礼仪格格不入。     

Incubation of an industry: Heterogeneous knowledge bases and modes of value capture

Research summary : We examine firms' technological investments during an industry's incubation stage—the period between a technological breakthrough and the first instance of its commercialization. Using the agricultural biotechnology context, we develop stylized findings regarding the understudied knowledge evolution preceding product evolution in an industry's life cycle, the trend and diversity of firms undertaking technological investments in anticipation of industry emergence, their leverage of markets for technology and corporate control, and their use of alternative modes of value capture. We juxtapose these stylized findings with existing literature to identify new theoretical insights, and set the stage for future scholarly work to develop and test new theories for the incubation period, examine its existence in other industries, and study its impact on subsequent firm and industry evolution. M anagerial summary : New technological breakthroughs present managers of existing firms and aspiring entrepreneurs with opportunities to create altogether new industries. During the vibrant incubation period, we find that multiple firms capitalize on diverse knowledge bases to shape the industry's knowledge evolution and also capture economic value in diverse ways. Existing firms in the obsolescing industry are more likely to become targets in acquisitions given their complementary knowledge. Science‐based start‐ups are more likely to engage in acquisitions and collaborations with established firms. Diversifying firms are more likely to commercialize products after leveraging of internal development, acquisitions, and alliances. Our study highlights the importance for managers to think about “success” and “failure” across multiple yardsticks of performance, rather than only as product commercialization as the sole goal.

Research continuum on consumer education and brand knowledge: A critical analysis

Consumer education and brand knowledge have emerged as the dynamic tool in the complex marketplace today that actively stimulate the cognitive behavior of consumers toward developing purchase intentions and buying decisions. The general objective of this study is to critically review the previous studies on the role of brand literacy, transfer and perceptions of knowledge, purchase intention, shopping ambiance and customer satisfaction, and illustrate the consumer decision making process induced by the above factors. The literature review reveals that brand education plays significant role as a driver of decision making among consumers, which not only empowers consumers in developing perceptions on the brand but also helps the companies on brand co-designing and knowledge dissemination process. Consumer literacy and brand knowledge helps the consumers in assessing the brand value, competitive advantage, and operational efficiency of the brand toward building purchase intentions. The effects of the increasing levels of customer expertise in the marketplace today is seen as the outcome of consumer education and perceived brand knowledge.     

A new professionalism for agricultural research for development

There have been repeated calls for a ‘new professionalism’ for carrying out agricultural research for development since the 1990s. At the centre of these calls is a recognition that for agricultural research to support the capacities required to face global patterns of change and their implications on rural livelihoods, requires a more systemic, learning focused and reflexive practice that bridges epistemologies and methodologies. In this paper, we share learning from efforts to mainstream such an approach through a large, multi-partner CGIAR research program working in aquatic agricultural systems. We reflect on four years of implementing research in development (RinD), the program’s approach to the new professionalism. We highlight successes and challenges and describe the key characteristics that define the approach. We conclude it is possible to build a program on a broader approach that embraces multidisciplinarity and engages with stakeholders in social-ecological systems. Our experience also suggests caution is required to ensure there is the time, space and appropriate evaluation methodologies in place to appreciate outcomes different to those to which conventional agricultural research aspires.     

The changing US–China investment relationship

The United States and China are at a turning point in their investment relationship. China’s previous investments in the United States were predominantly in government securities, while other holdings were negligible. Recently, the accumulation of treasury securities has slowed and direct investments by Chinese firms have risen steeply, with Beijing signaling greater support for portfolio investment outflows as well. This article describes the nascent shift in patterns of Chinese investment in the United States and uses the case of direct investment to examine the implications for US–China relations. We discuss current and future policy issues presented by Chinese foreign direct investment (FDI) in the United States, including national security, market access, and antitrust.     

Can household-based food consumption surveys be used to make inferences about nutrient intakes and inadequacies? A Bangladesh case study

Household Consumption and Expenditures Surveys (HCES) are increasingly being used to make inferences about individual food consumption, despite the fact that they collect food data at only the household level. Usually the analysis assumes that the household’s food is distributed among its members in direct proportion to each member’s share of the household’s total energy requirements; what is referred to as the adult male equivalent (AME) approach. Using the 2011–2012 Bangladesh Integrated Household Survey—which collected consumption data for all members of rural households using combined 24-hour recall (24HR) and food weighing methods—this study directly compared probability-based average estimates of intakes, intake gaps, and the prevalence of inadequacies as estimated by the 24HR and those calculated using the AME approach for energy and each of four micronutrients: vitamin A, iron, zinc, and calcium.At the population level, for iron, vitamin A, and calcium, more than 97% of all individuals had the same estimated prevalence of adequate or inadequate nutrient intakes using 24HR and AME-based estimates. In the case of energy and zinc, roughly 77 and 83% of the sample population had identical adequacy statuses, respectively. The magnitude of inadequacies (the nutrient gaps) differed by 8 percentage points for energy and less than 3 percentage points for the four micronutrients. Disaggregating intakes and inadequacies by age groups revealed that the vast majority of variance between the two methods was highly concentrated in the first few years of life. Children 3 years of age and younger constituted 7.5% of the population but had 13.1% of the inconsistencies in intake adequacy status. 54% of children 3 and under had at least one pair of inconsistent prevalence estimates. While there are important differences in the levels of estimated energy and micronutrient intakes using 24HR and the AME-based estimates for children 3 and under, the results are remarkably comparable for the rest of the population.     

Understanding the effect of personal and social value on attitude and usage behavior of luxury cosmetic brands

The growth of the luxury market has been phenomenal in recent years, especially in the emerging markets such as India. This research studied luxury value aspects (personal and social) of luxury cosmetic brands and their impact on consumer attitudes and usage behavior, with a focus on women consumers. Data was collected in the form of a survey from 372 women luxury cosmetic users. Structural equation modeling was used to analyze the framework. Hedonism and status value were found to have high significant relationship towards attitude whereas usage behavior was influenced by materialism and status value. Hence the symbolic and psychological traits among consumer will show their willingness to buy and preferences on luxury cosmetic brands. The findings of this study provide valuable insights to marketers and managers to understand consumer trends, attitudes and behavior in the luxury cosmetic market and develop marketing strategies to successfully market their products.     

Herding behavior in the Pakistan stock exchange: Some new insights

This study attempts to examine the presence of herding behavior in the Pakistan Stock Exchange (PSX). The novel contribution of this paper is that it investigates the herding phenomenon from a large number of facets such as herding of firms towards market, herding of firms towards industry portfolios, herding of industry portfolios towards market, herding in mostly traded stocks and in large and small stocks, and herding in the crisis period. For this purpose, we use the herding behavior model of Christie and Huang (1995) on the daily closing prices data of 609 firms listed on the PSX from January 2004 to December 2013. Results show that individual firms do not herd towards market index, except when the market experiences a negative return of 5%. However, when we sort firms into small and large groups based on median market capitalization, results indicate that large firms show herding behavior in extreme market movements. Further, we find that firms in several industries herd towards their industry portfolios. However, we find weak evidence of industry portfolios herding towards the market. We also segregate the impact of financial crisis of 2008 from normal times. These findings support results of our baseline estimation.     

产业分工、国际贸易摩擦及我国的对策——基于价值链视角的研究

国际分工格局的改变引致国际贸易格局随之改变，发达国家为持续占领和控制国际分工的主动权，必然采取保护相关措施抑制发展中国家急速扩展的国际贸易业务，进而减弱发展中国家在全球价值链分工体系中的位置，这就必然导致国际贸易摩擦事件频发。基于经济学视角，为了顺利推进我国开放型发展战略的实施，减缓我国国际贸易摩擦的困扰，未来应从内部层面继续加快中国开放型经济转型升级的步伐，创新对内对外的开放模式；从外部层面加速价值链升级工程建设，提升我国在全球价值链分工体系中的地位，逐渐摆脱贸易摩擦的被动地位。
