"And why Shanghai and Tokyo are not"
alephnerd•1mo ago
> One model is Shanghai, which is run by the central government as a province rather than a city

> The Tokyo Metropolitan Government (tmg) is responsible for big-ticket public services such as water, sewage and public hospitals. Beneath it sit 23 wards and a host of peripheral cities and towns. Each municipality has its own elected mayor and assembly, responsible for services such as schools, waste management and community planning. The tmg co-ordinates between them. It is a sensible split that clearly delineates authority while also making sure that decision-making is joined up.

jhancock•1mo ago
The high level description for Tokyo's management could apply to Shanghai. Replace Tokyo's "elected mayor/assembly" with "party member administrators". Each Shanghai district has its own management structure.

The vague description "run by the central government as a province rather than a city" is uninformative.

Lived in Shanghai 10 years. The city is well run for something of its magnitude. Mostly competent leadership and cultural alignment.

alephnerd•1mo ago
It's a broad statement but the fact that Shanghai is a 直辖市 (and imo Tokyo is in a similar position) is a major difference from other megacities in Asia.

It gives Shanghai (and Tokyo) a munucipal budget and fiscal autonomy that most other megacities in Asia tend to lack.

seanmcdirmid•1mo ago
Shanghai usually gets the CPC members running it who will lead the country in the future. So...the future president of China is likely to be a party secretary of Shanghai at some point (like Xi in 2007). Any cadre who is favored and wants to be seen making modern impacts will be sent to SH.

Southern Chinese cities are better run than Northern Chinese cities. Not just Shanghai, but Hangzhou, Suzhou, Nanjing, Wenzhou...heck, even Kunming has better drivers and traffic than you'll see in Beijing.

alephnerd•1mo ago
> heck, even Kunming has better drivers and traffic than you'll see in Beijing.

But, conversely, a poor farmer in Yunnan was less likely to choose to become a migrant worker in Kunming instead of a Tier 1 metro.

IMO, Beijing's craziness can be attributed to the fact that it is the economic center for much of Northern China - and a number of migrants from large neighboring laggard states like Hebei, Shanxi, Henan, and others ended up gravitating to Beijing.

> Shanghai usually gets the CPC members running it who will lead the country in the future

Not anymore. That was more of a Jiang- and Hu-era bias.

> a party secretary of Shanghai at some point (like Xi in 2007)

Xi's tenure in Shanghai was transitory (less than a year from what I remember) and imo was due to his previous role in Zhejiang.

> Hangzhou, Suzhou, Nanjing, Wenzhou...

Those are all closely connected with Shanghai economically speaking, and all part of Zhejiang or Jiangsu.

The problem in Beijing that everyone on the road was an official or related to an official, so the police couldn't do traffic stops without risking their careers. That has changed a bit, and they invested heavily in the Black Audi police (CPC police who are allowed to police official and their families) to counterbalance the chaos that everyone being connected caused.

> Xi's tenure in Shanghai was transitory (less than a year from what I remember) and imo was due to his previous role in Zhejiang.

Not that we have much to go on since Xi is president for life now, but I bet the next leader of China does their time in Shanghai like the previous ones.

> Those are all closely connected with Shanghai economically speaking, and all part of Zhejiang or Jiangsu.

Wenzhou is more a Fujian extension, Zhejiang and Jiangsu are China's richests provinces, and I think Hangzhou has left Shanghai's shadow by now.

We can also throw in Guangzhou and Shenzhen, but in general even the poorer southern cities (Kunming, Guiyang, I kind of want to say even Changsha and definitely Wuhan/Chongqing) are and have been well organized.

The article argues they are miserable because their governance is subpar with many factions controlling different aspects as well as lacking coordination with neighboring peripheral governing bodies and all this ends up in poor services for residents. People more there for opportunity and the opportunity appears better in those miserable places than in the hinterlands... and so they move.

somewhat interesting right? ho chi minh, instead of combining with adjoining areas into a "metro hcmc" like metro manila, actually spun off thu duc..

and yeah. dmk airport is inside bangkok while bkk is in the next province.. why only can color within the lines?

wenc•1mo ago
I live in NYC. That sounds more like NYC.

Most mega cities in Asia Pacific at least have newer infrastructure and social norms that make them less miserable.

NYC is miserable in some ways (crumbling infrastructure, broken social norms especially post COVID) and not in others (creativity, passion).

Some days I feel the latter makes up for the former. But the former is still bad.

I wish they left space to discuss the Japan’s Furusato Nōzei and China's Hukou system and how they impact non-residents.

For example, if your hukou is registered to a rural community, you do not have access to the same level of public healthcare that people with Shanghai hukous have.

edit: replaced 'Jūminhyō' with Japan’s Furusato Nōzei

tdeck•1mo ago
I don't think the Jūminhyō system is similar to the Chinese one. You basically just need to have a utility bill or something with your name and address on it, and register it with your local ward office or city hall. There is no concept of being refused it unless you aren't a legal Japanese resident as far as I can tell?
itake•1mo ago
I misunderstood the name. I think I mean: Japan’s Furusato Nōzei.

This system creates weird incentive schemes where rural areas offer 'benefits' to city folk.

_--__--__•1mo ago
It's a fully voluntary program and the annual 'benefit' is usually something like a box of local produce or a reduced fee ryoukan stay, it's hardly something that affects urban quality of life.
thoweirweer•1mo ago
住民票 (Jūminhyō) is just a certificate of residence - there's no population management aspect to it unlike China's Hukou.
mjyut•1mo ago
Regarding the Japanese system, there are no restrictions on moving residence. Resident registration (Jūminhyō) can be done anywhere. Therefore, if you move to a new place of residence, it is common and recommended to register accordingly. I don't know the details, but I think the system in China is probably completely different.

India's capital Delhi's recent air quality woes spring to mind.

https://www.youtube.com/watch?v=aAoJYJR8o3g

alephnerd•1mo ago
Delhi's issues are severe due to the coordination problem - you have 6 state governments, 1 municipal government, the central government, and SOEs all with overlapping or competing responsibilities.

Hanoi has the exact same coordination problem as Delhi for the exact same reasons as well - 8 tinhs and 2 TPTTTWs all with overlapping and competing governments.

Beijing had a similar problem both Delhi and Hanoi, but because it was just surrounded by Hebei and Tianjin (a fellow 直辖市) it made coordination easier.

Why do we group East Asia with South Asia? We don't group the Middle east with Europe
SanjayMehta•1mo ago
The Middle East is being called West Asia these day.

South Asia is another new invention.

No one goes around saying "I'm a South Asian."

As for terminology, especially when it comes to geography and geopolitics, it depends on who's using the term and what their agenda of the day is.

Gulf of Mexico comes to mind.

lazylizard•1mo ago
"south asia" is the area thats in-between the gulf cooperation council and asean?

theres no south east asian or east asian person either...

Actually many US companies tend group them ridiculously as EMEA
amrocha•1mo ago
This is such a terrible article.

Comparing India and Indonesia to China and Japan is like comparing Mexico and Brazil to Canada the US.

Just because they’re in the same continent doesn’t mean they’re comparable.

SanjayMehta•1mo ago
What makes the article even worse is The Economist's policy of hiding the author(s) name(s).

The name is always a giveaway of their agenda.

kkfx•1mo ago
In the past, for technological reasons, because it is technology that determines every civilisation, cities were rich places, because they had trade, nearby arts and crafts; knowledge and economy travelled in this way.

Today, for similar reasons, cities are chicken coops where the inmates are not much different from the human batteries in The Matrix; they live to work, generally without realising it, for masters who are no longer in the city. Technologically, they are failed places, because they cannot evolve without being rebuilt from scratch, and they cannot be rebuilt on such a scale, both due to the impact of the work and the quantity of raw materials required.

Most people never weigh the real cost of a modern city; they are so accustomed to owning nothing that they think what is there is natural, ignoring what they don't see, whether underground (like the cathedral with mega-pumping stations to mitigate flooding beneath Tokyo) or in the surrounding areas to bring water and food, because we all eat, but in the city no one produces.

The cities of the coming century are ghettos, polluted and devastated, where misery is concentrated like a compound, while wealth leaves the compound to reclaim life in nature.

archagon•1mo ago
That is an utterly cartoonish take on city life and does not match my experience at all.
