技术扩散与全球技术二元现象研究初探

以技术贸易、FDI、国际技术联盟和海外R&D活动为主体的全球技术扩散活动使得技术在全球范围内的流动更加活跃,技术先进国家对技术落后国家的技术扩散和转移,使技术落后国家的技术和经济发展水平得到了提高,但是,这并没有减轻全球的技术二元现象,相反,伴随着经济全球化进程的加快与深化,全球技术二元现象更是日益凸显。本文从技术扩散的研究视角出发,分析了全球技术二元现象形成和加剧的原因,也指出了为什么有些技术落后国家和地区能够突破技术二元的壁垒,在全球技术扩散的浪潮中加强自己的技术地位,逐渐缩小与技术发达国家和地区的技术差距,从而成为全球新的技术增长点,为技术落后国家和地区通过改善技术扩散通道和提高技术势能,来改变其在全球技术格局中的地位提供了理论借鉴。

The multilevel analysis of students’ achievement: Evidence from Morocco

This paper, using multi‐level modelling, sought to highlight student‐level and school‐level characteristics that differentiate the academic performance in mathematics from a sample of 6080 Moroccan secondary students who participated in the 2011 Trends in International Mathematics and Science Study (TIMSS) test. The results indicated little evidence to support the Heyneman–Loxley effect, as they showed that individual and family characteristics were the strongest determinants of achievement compared to the schools’ factors. Students scored higher when they were boys, were younger, were more self‐confident, were more ambitious, and felt secure in school. They also scored higher when they came from families with a higher socioeconomic status, particularly when their parents were able to ensure the availability of learning resources, and were of a higher level of education. Finally, schools were matter for their pupil achievement mainly through the location channel, as urban pupils outperformed rural ones. However, the other school characteristics, including those related to teachers, played a negative, or at best neutral, role in pupil outcomes. These findings have important public policy implications. Redesigning education policy towards improving the school's environment and fostering inclusivity would be needed to enhance learning performance of Moroccan students.

Spread of E-commerce,prices and inflation dynamics: Evidence from online price big data in Korea

The so-called Amazon effect is generally defined as such that the increasing competition in the online market and between online and traditional retailers is reducing retail markups and putting downward pressure on prices. This paper investigates the existence of the Amazon effect using online price big data in Korea where e-commerce has been rapidly spreading. For this task, the direct comparison between the online and offline prices were conducted in terms of the levels, trends, inflations, and dynamic correlations for two prices. Online prices for products were collected and classified under the identical classification in the CPI for 14 items in two divisions: food and non-alcoholic beverages and clothing and footwear. Laspeyres formula with identical weights as for the CPIs was applied to compilation of the item- and division-level OPIs (online price indexes) from July 2018 to June 2019. The empirical analyses overall indicated that persistent decreasing trends in the online prices were found when compared to those in the offline prices represented by the CPIs, indicating the existence of the Amazon effect in Korea. More specifically, the OPI covering two divisions decreased by 1.8%, while the CPI increased by 3.6% for the period. In addition, the close dynamic correlations between on-month inflations of two indexes were also found in panel regression and VAR estimations, indicating that a 1% increasing shock to OPI inflation led to an around 0.3% increasing response in the CPI inflation. The dynamic correlations, however, were quite different across the divisions. Those were more pronounced for the division of food and non-alcoholic beverages while they were found little in the division of clothing and footwear.

SCIENTIFIC BREAKTHROUGHS AND NETWORKS IN THE CASE OF SEMICONDUCTOR LASER TECHNOLOGY IN THE US AND JAPAN, 1960s–2000s

United States organisations took a clear lead in semiconductor laser research until the mid‐1970s. After the 1980s, many important breakthroughs were developed by Japanese organisations. Exploring the journal Applied Physics Letters, this study examines how semiconductor laser technology developed in these two countries and how this change in the country‐level industrial leadership in the scientific research occurred. Examining the relationship among industrial organisations, research networks, and scientific breakthroughs, it discusses how these coevolved and how breakthroughs were channelled in different directions. R&D targets were channelled into small markets in the US, but were concentrated into the same markets in Japan.
