&gt; What&#x27;s the future for those Chinese Megacities? I&#x27;m not sure we see a linear&#x2F;whatever development of them over the next decades.<p>Individual cities like Beijing and Shangai are peanuts compared to what is coming. I don&#x27;t know if you are aware and if that is what you were referring to with &quot;Chinese Megacities&quot;, but the Chinese government is working to tightly integrate larger regions. Some very explicitly directed from the central government, some thanks to city&#x2F;province level cooperation.<p>E.g. the Bohai Economic Rim[1] include cities like Beijing and Tianjin. Currently about 66 million people in the whole area. There&#x27;s work underway to tie them together with high speed rail, more highways, combining communications networks, government structure etc. Some projections suggest that all of the Bohai Rim will merge into a megacity with 250m+ people over the next few decades.<p>Then there&#x27;s the Pearl River Delta [2], which includes Hong Kong, Guangzhou, Macau, Shenzhen, Dongguan and a number of other large cities, and which is headed in the same direction. Depending on how you count, the PRD is already the largest metropolitan area in the world with the number of people ranging from somewhere around 63million people and up to 120 million.<p>Then there&#x27;s the Yangtze River Delta [3], which may compete with PRD for the largest population - the main contention is whether the YRD is one metropolitan areas or series of adjacent ones - it&#x27;s not as tightly integrated as the PRD. Yet. But it has 140 million inhabitants, and includes cities like Shanghai, Nanjing, Hangzhou etc.<p>Chances are all three of these will in practice merge. Whether or not they will be unified to the point of being governed like cities is another matter (they are large enough that currently they straddle multiple provincial boundaries.<p>[1] <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Bohai_Economic_Rim" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Bohai_Economic_Rim</a><p>[2] <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Pearl_River_Delta" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Pearl_River_Delta</a><p>[3] <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Yangtze_River_Delta" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Yangtze_River_Delta</a>
