State-led technological innovation of domestic firms in Shenzhen,China: Evidence from liquid crystal display (LCD) industry

Since 2000, particularly in the aftermath of the global financial crisis, there has emerged revisit of the role of the state in technological upgrading of latecomer cities and regions in developing countries, including China. The effectiveness of a technological innovation strategy driven by transnational corporations (TNCs) has been questioned, despite its significant contribution to rapid industrialization via strategic coupling in the global production networks (GPNs). There has been a paradigm shift of innovation policy towards indigenous innovation through state-led explicit coupling of designated domestic firms and lead firms in the GPNs. The practice of this remains understudied, however. By examining the development of the liquid crystal display (LCD) industry, one of the strategic emerging industries (SEIs) in Shenzhen, this paper sheds light on the collective roles of various state authorities ranging from the central to provincial and municipal governments in fostering technological innovation of domestic firms (e.g. CSOT) through explicit coupling with global lead firms (e.g. Samsung). The empirical experience in Shenzhen indicates that indigenous innovation focused on domestic firms may unnecessarily exclude the participation of TNCs. This study urges more research to examine the changing dynamics of technological catch-up of domestic firms in an increasingly globalized and uncertain world economy.     

Development of a transparent single-grid-type micro-strip gas chamber based on LCD technology

The liquid crystal display (LCD) technology allows several simple circuits to be built using thin film transistors, thus making fabrication of compact, integrated, large-area, and low-cost micro-pattern gaseous detectors possible. In this work, a single-grid-type micro-strip gas chamber (S-MSGC) using transparent electrodes based on the LCD technology was fabricated and successfully operated in several gas mixtures. The detector was coupled with a multi-pixel photon counter to detect an optical signal through the transparent substrate in Ar/CF₄ gas. Both electrical and optical signals were measured and the light yield of the detector was acquired. Successful operation of the S-MSGC can be considered the very important first step for development of the next target of integrated devices.
