Shanghai rationed car ownership by auction; the plate came to cost more than a small car

By the mid-1990s Shanghai faced the problem every growing city now has: car ownership doubling while road space stays put. From 1994 it chose the bluntest instrument in the economists' toolkit — it stopped giving away the right to put a private car on the road and started auctioning it. Beijing kept handing out plates nearly free; a Shanghai plate cost, by one resident's 2011 count, a hundred times as much as one in Beijing.

The format is a fixed monthly quota sold to the highest bidders. In November 2010, 13,429 people bid for 8,500 plates and the average winning price was 45,291 yuan. The price kept climbing with incomes: from 50,000–60,000 yuan in 2012 to around 90,000 yuan, where it stuck after May 2017 — for roughly 9,000 plates a month, with winning odds between 4 and 8 percent. Residents call the plate 'the world's most expensive sheet of iron'; the steel under it — a small car — can cost less.

The mechanism does two jobs at once. It rations road space by willingness to pay, and it routes the scarcity rent into the public purse: from 1994 to 2008 the auctions raised more than 15.55 billion yuan, about 14 billion of which went into public transport — ring roads, subway lines, bus and ferry subsidies.

It also has a leak the city learned to love: since late 2016, new-energy vehicles get a plate free. Buyers who gave up bidding switched to electric cars, and the city's NEV fleet grew from about 35,000 in 2015 to nearly 240,000 in 2019 — around 10 percent of its private vehicles.

Sell the plate, don't queue it: price the ration

An auction replaces an invisible ration with a visible price, so the plate goes to whoever values it most rather than to whoever wins a queue or a lottery.

The scarcity rent is captured by the city, not scalpers: auction revenue became the funding base for the transit that substitutes for the car.

The quota is set month by month, so the city can tune car growth to road capacity without re-legislating every time demand moves.

A price is honest about the trade-off: a free lottery hides the cost of car growth, while a 90,000-yuan plate makes every bidder feel the road space they consume.

When you must ration something scarce, auction the right instead of queueing it: the price reveals real demand, the state captures the scarcity rent, and the revenue can buy the alternative.

Beijing's 2011 lottery drew 100,000 applicants in its first 12 days — demand did not go away, it just queued. Shanghai's price stayed pinned near 90,000 yuan, and the free-plate exemption for electric cars turned the auction into industrial policy: by 2019 nearly one in ten of the city's private cars was an NEV. In March 2025 the State Council told quota cities to shift from purchase controls to usage-based regulation, and Shanghai widened access to its auction by cutting the social-security requirement for bidders from three years to one.
