Lurking silently behind practically every story on Chinese economic growth over the last thirty years has been the country's unprecedented shift from being an overwhelmingly rural society to what is now a largely urban one, with almost 700 million urban residents now outnumbering their rural counterparts.Joining Kaiser Kuo and Jeremy Goldkorn to talk about the biggest migration in human history is Tom Miller, analyst at GK Dragonomics and author of the newly-published China's Urban Billion. If you find this topic as fascinating as we do, join us for an in-depth discussion of why China has reluctantly embraced urbanization, and how the resulting pressures are forcing changes in China's hukou system, land-usage rights, and ask with us whether these changes are pushing cities like Beijing into a new kind of urban dystopia.ANNOUNCEMENT: This week let us mention as well that we're trying something new next week: a call-in show featuring Kaiser, Jeremy and Gady Epstein from the Economist. Also in the show will be whatever questions and comments you'd like to throw their way. So if you've got any thoughts you'd like to throw into the fray, record yourself asking the question and send it in to us at email@example.com. We'll cover as many submissions as we can. Details on our Facebook page.On a separate note, we usually take a minute before each show to remind you that it is possible to subscribe to Sinica by RSS, as well as share a link you can use to download this show as a standalone mp3 file.
