Taiwan is special for two reasons.
1. Taiwan has a cumulative 137,867 USPTO patents (which makes Taiwan the third-highest foreign USPTO patent holder after Japan and Germany). Taiwan is a technological powerhouse. In comparison, Hong Kong is merely a financial center.

2. Taiwan is responsible for 60% of Chin'a high-tech exports. This was still true in 2012.
2005 Citation:

(Page ii, first paragraph under Executive Summary): "Taiwanese electronics companies now carry out roughly a third of their production in China, and collectively account for around 60% of China's total information technology exports."
2012 Citation:
Why Taiwan Is Asia’s Hidden Tech Mecca | Uncommon Wisdom Daily
"More than 60% of Chinese technology exports are made by Taiwanese companies. What that means is that most of the technology profits coming from anything stamped with 'Made in China' are probably going to Taiwan."
----------
Many of Taiwan's technologies have migrated to China. Notebook computers are now produced exclusively on the mainland. Another example is that China's SMIC is comprised of ex-TSMC employees. It is common for mainland Chinese companies to hire Taiwanese experts. If someone asks, I will use cutting-edge LED technology or specialty chemicals (citation from New York Times) as an example.
Taiwan is the third country in the world to build a sub-micron machine tool (after Japan and Germany). The last citation that I have from 2012 shows China can build a 3-micron machine tool. Taiwan built its first machine tool in 1954. It is reasonable to believe that Taiwanese machine-tool technology has migrated to China. Outside of the West, only Taiwan and China build CNC five-axis machine tools. Taiwan got there first. The West most certainly would not help China to build advanced CNC five-axis machine tools. Given the rapid rise of Chinese CNC five-axis machine tool manufacturers, a reasonable inference is Taiwanese help. Russia still can't build its own indigenous CNC five-axis machine tools. China leapt past Russia with Taiwanese technology transfer.
Taiwan's cumulative USPTO patents are clearly massive in terms of quantity. However, we have to examine the quality of the Taiwanese patents. This can be done indirectly and easily by mentioning ten large leading Taiwanese companies in diverse industries.
1. TSMC (or Taiwan Semiconductor Manufacturing Company) is the world leader in the foundry business with 50% worldwide market share. TSMC logic chip technology is currently being mass produced at a leading-edge 20nm.
2. Mediatek is a leading multi-billion dollar designer of systems-on-chip (SOC) for smartphones and tablets.
3. Quanta and Compal produce 80-90% of the world's notebook computers with Taiwanese patents.
4. AU Optronics is a leading LCD manufacturer. AU Optronics won a monstrous patent lawsuit against South Korea's LG where a U.S. Federal District Court ruled that LG infringed on four key AU Optronics patents.
5. Epistar is a leading LED manufacturer with 1,000 LED patents.
6. Formosa Plastics is a leading manufacturer of specialty chemicals.
7. Taiwan is the world's fourth-largest machine tool exporter and has built a sub-micron CNC machine tool.
8. "Delta Electronics, Inc. (Chinese: 台達電子工業股份有限公司), founded in 1971, is the world's largest provider of switching power supplies and DC brushless fans,[1] as well as a major source for power management solutions, components, visual displays, industrial automation, networking products, and renewable energy solutions. Delta Group has sales offices worldwide and manufacturing plants in Taiwan, China, Thailand, Mexico, India and Europe."
9. "In Taiwan, which has the second-largest chip-design industry after the U.S., Novatek is a standout. Chairman Ho Tai-shung has turned it from a little spinoff of United Microelectronics (the Taiwanese chipmaker that is the world's second-largest foundry, behind only neighbor and rival Taiwan Semiconductor Manufacturing) into a chip-design powerhouse. Novatek, based in Taiwan's premier high-tech zone, the Hsinchu science park, is the island's dominant provider of TFT-LCD driver and controller chips, key components in the liquid crystal displays used in PC monitors and TV screens."

10. "Largan is the world’s biggest designer and manufacturer of imaging lens products used in mobile devices." (from Bloomberg News)
