Strictly speaking, a book translated from English into Chinese and a book published by a domestic publishing house are not the same book. I define "the same book" as a book with the same ISBN code. First of all, let's take a look at the price comparison of the book "The user is always right: a practical guide to the creation and use of Web personas" at home and abroad. As mentioned above, Chinese books published by domestic publishing houses and English books published abroad are not "the same book" in a strict sense, and there is no comparability in themselves, so the disparity in price difference is normal. Then why is there a price difference between two Chinese and American sites in the same book (ISBN is the same)? One of the reasons is that books published abroad are imported books sold in China, which need to be subject to VAT at the rate of 13%. On September 3, 2007, the Ministry of Finance and State Taxation Administration of The People's Republic of China notified Caishui [2007] No.65 on adjusting the VAT rate of audio-visual products and electronic publications: With the approval of the State Council, the VAT policy of audio-visual products and electronic publications is hereby notified as follows:1.From September 15, 2007, the VAT rate of audio-visual products and electronic publications will be reduced from 65438. Two, the term "audio and video products" as mentioned in this notice refers to audio tapes, video tapes, records, laser discs and laser discs. 3. The term "electronic publication" as mentioned in this Notice refers to the mass media that edit and process pictures, words, audio-visual and other content information. In the form of digital code, it is stored in magnetism, light and dielectric with a certain physical form and used by computers or devices with similar functions to express ideas, popularize knowledge and accumulate culture. For the commodity names and tax numbers of electronic publications, all taxable VAT commodities in China are levied at an ad valorem rate, and the basic tax rate is 17%. However, for some important materials related to the national economy and people's livelihood, the VAT rate is even lower, at 13%. The VAT rate of the following goods is 13%:

1. Grain, edible oil and vegetable oil;

2 tap water, heating, air conditioning, hot water, gas, liquefied petroleum gas, natural gas, biogas and coal products for residents;

3. Books, newspapers and magazines;

4. Feeds, fertilizers, pesticides, agricultural machinery and plastic films;

5. Metal minerals, nonmetallic minerals and other products (excluding gold powder and forged gold, with zero tax rate);

6. Other goods specified by the State Council.
