I listened to this during my morning commute. It's amazing to me how easy to is to admit problems once they are too obvious to ignore. The fact that real estate is ~30% of Chinese GDP is bonkers. And the authorities sat on their asses and did nothing for years on end until it blew up in their faces. Should disabuse people of the notion that China is immune to the financial speculation/excess model that the West is plagued by.
I like his criticism/analysis of what he calls the "platform economy" (think Didi) which is basically about taking lots of investor money during the rapid growth phase, then establish a semi-monopoly (or oligopoly) while collecting rents. Once you reach that rent-seeking perch, you do very little actual innovation. It's basically a new business model rather than genuine innovation is his argument, and I agree with him. He thinks it is good that the CPC is cracking down on those tech companies and re-directing investment towards "deep tech" or "hard tech" (think AI, semiconductors, etc). Again, I agree.
He then looks ahead and notes that while China's industrial production is very high, its value-add is quite low. It has increased in recent years but it still too low, which is why China is not yet rich. His solution is for China to focus climbing the value-add ladder in industry. This might work to perhaps double China's GDP per capita, but it ignores the key weakness of many East Asian countries, namely a weak service sector. You see this in South Korea or Japan too. Both countries have strong industrial companies but you look at the service sector and you see very little.
Even fairly stagnant countries like Italy is richer than South Korea or Japan and it's not like Italy is known for dynamism. Their reliance on tourism is also much less than e.g. Spain or Greece as a share of GDP. For very rich countries (think Switzerland, Scandinavia, Netherlands, US, Australia etc) then a competitive service sector is a must. One advantage China has against South Korea and Japan is a stronger IT services ecosystem, but after growing very rapidly during the 2010s they have sort of stagnated. I would have wished him speak a little about this, but he seems to think they are all part of his "platform economy" and thus unworthy of support. I think that is a mistake. Companies like Baidu should not be lumped together with those such as Didi.
What I liked about his talks is his manner of weaving through stock and flow ideas and variables, alternating between zooming in and out.
Economics, or its precursors like managing state and common people's welfare, was, is, and will be part and parcel of statecraft, at least in historical and modern Chinese setting. Being a part of statecraft, it's not perfect, a deliberate choice between competing morals, hence there are a lot of errors and mistakes given the circumstances, intended or unintended, foreseen or blindsided. One the feature is that you cannot stop something until a consensus formed that it should be or must be stopped. That's the nature of the political beast ; do not cry wolf until so many see the actual wolf, or a lot of wolf footprints and damages it causes, otherwise your political rivals will come and get you, sooner or later, one way or the other, your good intentions be damned. There is no fall guy for that. Ditto that to real estate sector, property tax, etc. So by nature, they tend to not pop the zit before its time.
Speaking of stock and flows, my original intention was that we should focus our approach to that kind of concept to widen the discussion and deepen the understanding, instead of heated arguments all hanged up on narrow specific areas like gdp, gdppc, etc, and mind you which are all man made numbers and concepts with their own shortcomings and innate flaws, one of them being a conceptual straitjacket that tries to fit real outside world into its construct, and just one of so many other data-points of equal or more importance to consider in a given circumstance, all of which nevertheless still fall under stock and flows ideas. One can easily look up what is this rather old concept on the web.
Well that's at least a suggestion since we are pretty tired of seeing a lot of good folks bogged down in heated arguments over little things and some got even booted out, even though they have some insights and info that we either do not have or overlook, rinse and repeat, so here is at least a suggestion, or a wish, to stop that.
