The government has played an important role in developing the tech sector, aided by a massive consumer market. In manufacturing, it intervened directly many times to reach the point where much of the world’s technology is made in China, even if it’s not always by Chinese companies. The central metropolis Zhengzhou, dubbed by locals as iPhone City, wouldn’t have become Apple Inc.’s biggest production base without government incentives. While less active in software and services, China facilitated their development by effectively creating its own version of the internet that’s blocked off from the rest of the world by what’s known as the Great Firewall. In the absence of Facebook Inc. or Twitter Inc., Tencent’s WeChat and Sina Corp.’s Weibo have flourished as social networks. Once Alphabet Inc.’s Google pulled out, Baidu Inc. extended its dominance of desktop search.
