What are the main export products of Zhejiang Yongkang?

You're right, those are Yongkang's main products, and there are many electric cars. . .

As for the annual export volume of products produced by local Yongkang enterprises, you can try to find out this data from the local foreign economic commission. They should have a rough figure (because not all products produced by Yongkang enterprises are exported by themselves, a considerable part of them are purchased and exported through foreign trade companies all over the country, so this data is only available to local government management departments).

In addition, Yongkang pays the national tax every year. You can go to the local national tax bureau to find out about the tax situation over the years. However, it should be noted that Yongkang's main export products can basically get tax rebates. So there is no such thing as "paying export tax". . . The actual situation may be that a large part of the value-added tax levied by Yongkang Local State Taxation Bureau on production enterprises is subsidized by export enterprises (not necessarily local production enterprises, but import and export trading companies in various provinces and cities) from the state.

Therefore, to know the actual contribution of Yongkang's industry to the national tax revenue, it is necessary to make corresponding tax refund deduction according to the tax amount and export volume.
