Technology Importation and Domestic Technology Acquisition in China from the Perspective of Innovation

Foreign and domestic technologies play different roles in a country's innovation. In recent years, Chinese firms have spent less on importing foreign technology and more on acquiring domestic technology. Based on the panel data model, state space model(SSM) and the Bayesian vector autoregressive model, this paper finds that the purchase of domestic technology plays a critical role in the innovation of high-tech firms with an elasticity coefficient higher than that of technology importation before 2010. China's high-tech firms can effectively absorb purchased domestic technology, which also brings about an increase in their independent R&D input and contributes more to innovation output than imported technology. Performance of technology importation is lackluster but shows an improving trend. Technology importation is not correlated with innovation output and has a substitutive effect with independent R&D input. China is yet to enhance its absorption of imported technology. Elasticity coefficient of technology importation turned positive in 2007 and increased year by year. China should promote synergy between technology importation and domestic technology acquisition.

A Historical Approach on the Opportunity to Acquire Technology Development Capability in Turkish Automobile Industry

Turkey has given importance to the development of the automobile industry since the Ottoman period.While the Ottomans,who were aware of the development process of the automobile industry in the world,provided transportation by horse-drawn carriage,they thought of importing automobiles for the Sultan and high-level bureaucrats in an effort to switch to automobile transportation.However,after the proclamation of the Republic,automobile production started,just like airplanes.While a factory was established for the production of a domestic aircraft,the first automobile production facility was established in Istanbul in 1929 by the American Ford company.This factory was closed after a short time due to the world economic crisis.After the activities of the Kayseri Aircraft Factory,which lasted until 1948,came to an end,this time,Revolution car prototypes could be manufactured completely domestically in 1961.After the project,which did not go into mass production,the KoçGroup started to produce the domestically-made Anadol car with technology transfer from multiple sources in 1967,but the production of Anadol continued until 1984.In 1971,Renault cars started to be produced under the French Renault license,and TOFAŞcars under the Italian FIAT license.Towards the end of the 1970s,creative imitation applications were made in TOFAŞcars with the bird series.In the 1990s,the production of Japanese Honda and Toyota and South Korean Hyundai cars started.In 2011,the idea of producing a domestic automobile emerged,the Devrim automobile was taken as an example in this project,the first Togg prototype was manufactured with technology transfer from multiple sources in December 2018,and it was announced that mass production would begin in March 2023.The 12-year period from 2011 to 2023 is too long for the creation of a domestic automobile.It has been understood that this long process has been passed in order to regain the pre-1980 level of technological ability.However,the most important thing is the transition from the creative imitation stage to the innovation stage.Our wish is that this process can be shortened with phase skipping approaches.

Enhancing mergers and acquisition quality,accelerating technological innovation and achieving the second leap of China's steel industry

Over the past 10 years, China＇s steel industry has made a substantial development in terms of scale, and has finally become a steel giant in the world. In the upcoming 10 years, fundamental changes will be made with the economic growth in China. Against this background, China＇ s steel industry will shift from a rapid development to a slow but sound development. In order to fulfill the second leap of China＇s steel industry, based on its current developing status and characteristics, and from the perspective of both national and corporate development, mergers and acquisition are both effective ways to raise the quality of the existing stock of asset in the steel industry, while technological innovation is the solid foundation for its second leap.

The emergence of digital storytelling and multimedia technology in improving Greek language teaching and learning： Challenges versus limitations

Greek schools are witnessing widening gaps between traditional definitions and applications of literacy, which include reading, writing and speaking in terms of exercises from school textbooks and contemporary literacy practices like digital storytelling, interactive multimedia use and online communications. Language and literacy teachers of primary education are called upon daily to bridge these contradictions through pedagogical and textual choices they make in classroom teaching. This paper reports an experimental study with children of the fifth grade at public Greek schools to apply modernist literacy approaches involving digital storytelling and online communication in improving language skills. The paper analytically presents the didactic examples of a thematic union within the framework of the Greek curriculum and the alternative assessment for the experimental teaching on digital technologies among mother tongue learners. The findings have implications for teacher＇s and student＇s education and also for the integration of a pedagogical-technological content of curriculum within the continuing debate of being culturally and equally literate in today＇s education.
