hosts around 4,200 Taiwanese enterprises and over 240,000 Taiwanese work in China. Although the economy of Taiwan benefits from this situation, some have expressed the view that the island has become increasingly dependent on the mainland Chinese economy. A 2008 white paper by the Department of Industrial Technology states that "Taiwan should seek to maintain stable relation with China while continuing to protect national security, and avoiding excessive 'Sinicization' of Taiwanese economy." Others argue that close economic ties between Taiwan and mainland China would make any military intervention by the PLA against Taiwan very costly, and therefore less probable. High-tech manufacturing Since the 1980s, a number of Taiwan-based technology firms have expanded their reach around the world. Computex, a trade fair held annually in Taipei, has rapidly expanded and become an important showcase for the ICT industry globally. Taiwan is a key player in the supply chain for advanced chips. Taiwan's rise in the key semiconductor industry was largely attributed to Taiwan Semiconductor Manufacturing Co. (TSMC) and United Microelectronic Corporation (UMC). TSMC was founded 21 February 1987 and as of December 2021 its market capitalization equated to roughly 90% of Taiwan's GDP. The company is the 9th largest in the world by market capitalization as well as the world's biggest semiconductor manufacturing company, surpassing Intel and Samsung. Its major customers include Qualcomm, Nvidia, Broadcom, Intel, AMD, Apple Inc., Ampere, Microsoft, MediaTek and Sony. In 2018, the company's N7+ node became the first commercial node to be made with EUV lithography, as well its N7 node being the first sub-10 nm node to enter volume production. TSMC was the first Taiwanese company to be listed on the New York Stock Exchange, under the trade name "TSM", in October 1997. As of Q4 2022, TSMC is responsible for 60% of the total semiconductor market making it the biggest foundry. UMC, another major company in Taiwan's high-tech exports and global semiconductors, does not however, compete with TSMC on advance semiconductor processes. Instead it competes with the American GlobalFoundries, and others, for less advanced semiconductor processes and for silicon wafers. Its major customers include, MediaTek, Texas Instruments, and Realtek. As of Q4 2022, UMC is the 3rd biggest foundry by market share, behind Samsung, controlling 6% of the total semiconductor market. Other well-known international technology companies headquartered in Taiwan include personal computer manufacturers Acer Inc. and Asus, as well as electronics manufacturing giant Foxconn.
