Comparative Study On The Growth Of Listed Companies In Chip Industry

With the introduction of "Industry 4.0" and "Made in China 2025",China's scientific and technological revolution and industrial revolution are deepening continuously.As the "heart" of all complete equipment in manufacturing industry,chip plays an important role in China's scientific and technological revolution.However,for a long time,China relies heavily on the import of chips,which brings great pressure to the country's information security and strategic pressure."Localization of chips" has become an important long-term national development strategy.In the face of huge domestic market demand and policy support,listed companies in the chip industry have a broad future prospect,and their growth has attracted the attention of the government,enterprises and investors.The research content of this paper is divided into the following three parts: Firstly,the value chain analysis method is adopted to analyze the current development status of the upstream,middle and downstream of China's chip industry value chain,and the distribution diagram of listed companies in China's chip industry in the industrial value chain is drawn,and the curve of industrial value chain with different characteristics is drawn based on the two major profit indicators.Secondly,based on the established growth evaluation index system,the growth score of 60 listed companies in the chip industry was calculated by factor analysis method,and the ranking was carried out on the total chain and sub-chain of the industrial value chain,so as to identify the leading enterprises in various segments.Finally,this paper selects the IDM leading enterprises in the chip industry value chain at home and abroad--Yang Jie Technology,Suzhou Goodnetium and Samsung Electronics for a comparative study of multiple growth cases,illustrating the growth status and existing gap between Chinese chip enterprises and international leading enterprises under the IDM mode,and providing reference for the growth of Chinese chip enterprises.Based on the above research logic,this paper draws three main conclusions: First,the value chain of China's chip industry has basically formed.Under different profit indicators,the value chain of the chip industry presents "smile curve" and "rainbow curve" respectively,and the upstream chip design has the highest added value.Second,chip industry in our country listed company growth performance,profitability and solvency in the chip industry growth is dominant,the value chain upstream,midstream and downstream of the leading enterprises in turn to collect the top science and technology,and Yang jie jie jie micro electricity science and technology,and the scores based on growth of industrial value chain has the characteristics of the "smiling curve";Third,for domestic and foreign IDM model leading enterprises with the layout of the whole industrial chain,there are obvious differences in growth.This paper may have certain innovation in research perspective and industrial selection,and it has certain reference significance when the government makes policies and provides financial support,chip enterprises analyze their own growth motivation and investors make effective investment.
