A Study on the Double Semi-Active Vibration Isolation System

This paper puts forward the concept of double semi-active vibration isolation systemutilizing the 'on-off' active damper and the 'on-off' active spring. Applying KBM Asympto-tic method, the vibration of the system in case of weak semi-active control is studied. ln pcactice, there are two types of vibration isolation. One is to isolate the transmitting of the cyclicunbalanced force generated by the revolving machine to the surroundings. The other is to isolatethe transmitting of the vibration displacement of the surroundings to precise equipment. Deduc-ing the influence of the roadway unflatness on vehicles also belongs to this type. For the firsttype of isolation system, the damper always dissipates energy, and the total work done by the spring in a vibration cycle is zero. For the second type of isolation system, the work done by the damper sometimes is positive, and sometimes negative. The damper dissipates less energy. The work done by the spring in a vibration cycle isn't zero, and it is usually positive. ln thispaper, the vibration isolation is refered to the second type. .

The ultimate target is to catch up with the world advanced level by means of technical upgrading and recreation based on technology importation and assimilation.

Technological Content of the Import of Services and the Transformation of Growth Patterns of China's Industrial Economy

Based on the latest approach for measuring technology content of import of services and with the contribution of total factor productivity(TFP) to gross industrial output as the indicator for measuring the growth pattern of China's industrial economy,this paper provides an empirical study on the effect of import technology content of trade in services on the development pattern of China's industrial economy between 2004 and2011.Result of econometric test reveals that the technology content of import of services has a significant positive effect on transforming the growth pattern of China's industrial economy.Moreover,import of new types of trade in services with high technology such as computer and information services has a much stronger positive effect compared with import of traditional trade in services with relatively low technology content such as transport.In terms of different industrial sectors,technology content of import of services has the greatest effect on transforming the development pattern of China's technologyintensive industrial sectors,followed by capital-intensive,resource-intensive and laborintensive sectors respectively.Transformation of the development pattern of China's industrial economy cannot be isolated from the system of global division of work.Against the backdrop of global service sector fragmentation,China should take the important opportunities in the development of global trade in services and give more attention to improving the quality of import of services in the interest of transforming the development pattern of its industrial economy.

Path Dependent Historical Development at Turkish Automotive Industry

Turkey’s automotive industry has begun to occur at a much earlier date compared to other developing countries,through licensing agreements to establish automotive industrial facilities,by importing a kind of technology.Attempts have been made in order to produce the domestic automobile road providing sectoral developments could enter another technology pathway.Moreover,the inventor of a very early date in the Fordist production system,such as 1929 by Ford Motor Company with the license agreement,as if he could provide for setting up production facilities in Istanbul’s company,this bad experience has refrained for years from entering as a manufacturer Ford Motor Turkey market.Thus,while Turkey is an attractive market for car production,on the other hand,sufficient improvement over time in the production of trucks and other automotive products,such as buses has not been achieved.The 1929 experience seems to have been effective in terms of Turkey.Because,it was necessary to wait until 1971 for OYAK and TOFAŞto establish automobile assembly facility with license agreements.With the start of production of two automotive industry facilities,there has been a significant increase in sectoral production figures,but this increase trend has not been sufficiently supported by the government through the incentive system and in the late 1970s the production of the automotive industry has declined.For the first time in 1961,efforts were made to produce a completely domestic automobile,although the prototype of the revolutionary car was successfully produced,mass production could not be started.Subsequently,the production of the Anadol automobile for the second time was tried by means of technology transfer from multiple sources and the serial production of this automobile continued for a while.However,since fiber glass bodywork was used instead of hair bodywork and export opportunities could not be found,production was stopped completely in the end of 1980s.In the 1980s,automobile production continued in two assembly plants and product diversification was carried out to increase the production volume.In the 1990s,three new assembly facilities,Honda,Toyota and Hyundai,were established and the number of assembly production facilities in the country increased to five and technology loyalty based on technology imports continued.Until 2014,the automotive industry continued to consist of five automobile assembly plants and other automotive products assembly plants.In 2015,it was announced to the public that a new domestic car prototype was produced.It was announced that the project will start mass production in 2019.However,it was determined that the prototype would be re-manufactured at the end of 2019 by making changes in the project and that it would be possible to start mass production in 2022.Thus,it is understood that the efforts to start mass production since 2015 can be concluded in 2022,i.e.7 years after the first prototype was produced.It can 161produce prototypes in a short period of four months in Turkey in 1961,as evidenced by an indication of the dependency on a long time wasting which is not technology importation pathway,such as five years.How to break the path of devotion demonstrates that it is a difficult job.Path dependency is thought to result from the education system.

Intellectual Property Rights and Patenting in China's High-technology Industries:Does Ownership Matter?

This paper aims to systematically investigate the impacts of strengthening intellectual property rights on patenting in China＇s high-technology industries and to explore the potential differences in response to patent reform by ownership. Empirical results show that the estimated patent elasticity of R ＆D is lower than that for OECD countries, indicating relatively low R＆D productivity for China＇s high-technology industries. The direct innovation effect of technology imports is negative, while the absorptive ability embodied in R＆D helps in gaining external sources of knowledge, thus contributing to innovations. Specifically, strengthening intellectual property rights can induce more innovations in terms of patents in China＇s high-technology industries and is particularly relevant to foreign-owned high- technology enterprises.

The Importance of Science and Technology for China

My talk is titled "the Importance of Science and Technology for China". Yet I begin not with what science can do for a nation, I begin personally - with what has drawn me personally to science. It is joy. I experience, quite selfishly and privately, joy when I engage in one of the greatest adventures of the mind:

The Structure of China＇s Imports： A New Framework

Using the elbow function method to determine the number of classification groups of goods and applying the K-means algorithm to classify technical goods, this paper constructs a scientific classification framework of commodity structure and then measures the changes in China ＂s import commodity structure. It is found, first, that from 2000 to 2012, the import commodity structure in China underwent structural change. Shares of non-agricultural primary products and high-technology products increased sigmficantly, whereas shares of low-medium-technology products and medium-high-technology products declined. Second, from 2000 to 2006, the overall technology level of China＇s imports declined, but then increased from 2007 to 2012. Therefore, the Chinese Government shouM increase the share of high-technology and extra- high-technology products in total imports to stimulate structural transformation in manufacturing industries to make full use of foreign advanced technology and to prevent stepping into a low-end import commodity structure.
