Electric car giant Tesla's Shanghai Gigafactory delivered an impressive output of 79,000 vehicles in November, representing a 15 percent month-on-month increase. 

This surge in production in East China's Shanghai contributed to Tesla's China sales of over 73,000 vehicles in November, setting a new monthly record for the year.

The boost in Tesla's sales was driven by a combination of government subsidies and the company's own promotional offers.

Since autumn, the national vehicle scrappage subsidy policy has been in full swing, offering up to 20,000 yuan (over $2,750) for motorists who trade in their old cars for new energy vehicles.

At the same time, Shanghai rolled out additional incentives to encourage the replacement of older cars. On Tesla's part, the company introduced a limited-time price reduction for its Model Y, slashing the final payment by 10,000 yuan until Dec 31. 

Tesla also extended its 5-year, zero-interest financing plan until the end of the year.

What's more, Tesla's Shanghai factory has achieved what's widely regarded as remarkable efficiency, with an annual production capacity of 950,000 vehicles. 

Every 30 seconds, a new car rolls off the assembly line. This efficiency – combined with the local sourcing of over 95 percent of parts from Chinese suppliers – has allowed Tesla to offer the lowest prices globally for its Model Y and Model 3, sometimes up to 185,000 yuan less than in other markets.

With its increasing local production and cost advantages, Tesla is said to be enhancing its competitiveness in China while contributing to the growth of the country's automotive supply chain, strengthening the "Made in China" brand on the global stage.
