Dig a little deeper, however, and the growth of China’s electric vehicle industry is rather less impressive than it first appears.

The rapid increase in electric car sales has been powered by generous government subsidies and incentives. Last year, China’s central government offered subsidies of 30,000 yuan (HK$35,000) to buyers of plug-in hybrid cars, and as much as 55,000 yuan to purchasers of pure electric cars. Some local governments offered additional subsidies of the same amount, to total 60 per cent of the vehicle’s sticker price.

Together, these reduced the price of electric vehicles so that they were competitive with conventional cars. However, in many cases, local governments offered additional incentives. In Shanghai, the buyers of conventionally powered cars can pay as much as 80,000 yuan at auction for a permanent licence plate. Licence plates for electric cars and plug-in hybrids are free.

The generosity of these subsidies produces some curious market distortions. For one thing, China is desperately short of charging stations to power up all the electric cars it has sold. As a result, private buyers tend to purchase plug-in hybrids to take advantage of the incentives, and then run them using only their conventional petrol engines. It makes economic sense for the buyers, but it’s deeply inefficient in energetic and environmental terms, exacerbating rather than alleviating roadside pollution.

Beijing’s strategy has produced other distortions, too. The prevalence of subsidies has meant almost every one of China’s 169 domestic car makers, most of which are backed by local governments, has rolled out models of electric car. The majority are low-tech and poor quality, and struggle to make sales in the commercial market.

As a result, the biggest customers for these cars are often the local governments that support their manufacture. This shows up in China’s quarterly sales figures for electric vehicles. In 2016, more than 40 per cent of all electric vehicles sales for the year were booked in the final quarter as local governments ramped up their purchases to ensure they met Beijing’s annual targets.

In many cases, these vehicles have been left idle to gather dust on government lots. In at least one example, the vehicles didn’t even exist. In 2015, a Suzhou company sold 3,000 phantom buses to the local government. Its actual sales of real buses for the year were reckoned at just 25.

In an attempt to tackle these distortions, Beijing has announced plans to reduce the central government subsidies for electric cars and to cap those offered by local governments. This year, the maximum central government subsidy for a pure electric car will be reduced from 55,000 to 44,000 yuan. And local government subsidies will be capped at half that.

China returns to micromanaging outbound investments

This, of course, will make electric cars a lot less attractive as far as buyers are concerned. So, to encourage the continued development of the industry, from next year Beijing is proposing to impose strict quotas for electric vehicle production on the country’s car manufacturers.

Under the new system, manufacturers that exceed their quotas will be awarded credits. Car makers that fall short of their quotas, which will include the big foreign backed joint ventures, will have to make up their deficits by buying credits from producers with an excess.

In other words, the big producers of conventionally engined cars will be forced to subsidise the manufacturers of electric vehicles. And more to the point, as far as Beijing is concerned, foreign-owned joint ventures will be compelled to subsidise indigenous manufacturers of electric cars.

It sounds like a clever plan. But it is unlikely to ensure China’s technological dominance of the global electric car market, as Beijing desires. Instead it will simply perpetuate the extreme fragmentation of China’s electric vehicle sector. Legions of small, locally backed manufacturers will continue to knock out their low-tech electric clunkers to win credits that they can then sell to bigger producers such as the foreign joint ventures. And the big producers will continue to build and sell the highly profitable conventionally engined, gas-guzzling SUVs that Chinese buyers actually want.

Why Janet Yellen’s slimming plans matter to Asia

Just as Beijing’s grand plan for global auto dominance failed to displace Japanese and Korean car manufacturers in the early years of this century, so its grand plan to win dominance of the world’s electric car market will fail in the coming decade. But then that’s the miracle of central planning for you. ■
