These policies have boosted sales of electric cars to Chinese consumers to 188,000 last year, easily ahead of the U.S., where 116,000 were sold.
At the BYD plant in Shenzhen, that growth in demand can be seen on the assembly line. BYD sold 62,000 electric vehicles to Chinese consumers last year and plans to at least double that number this year.
"We can see that more and more people already accept the new technology," said Michael Shu, general manager of BYD Auto Sales.
BYD's growth in electric cars comes after years of expanding from battery production into electric vehicles.
Berkshire Hathaway Chairman Warren Buffett liked the business so much that one of his conglomerates has a 10 percent stake in BYD.
While the Chinese government is pushing electric cars, analysts are wondering how quickly sales will grow given the challenges facing Chinese consumers who want an EV.
"Chinese consumers generally live in large apartment buildings, not in standalone homes where they can more easily have a charging solution," said James Chao, with the consulting firm IHS Automotive. "One of the conundrums for the EV buyer here is 'where do you charge it?'"
But Shu isn't worried.
