Book distribution is basically the "sales" of general commodities, and the forms of sales are wholesale, retail and group purchase. Because in the era of planned economy, after the publication of books, publishing houses are generally not responsible for the specific work of book sales, and the sales work is generally entrusted to Xinhua Bookstore Publishing House (all state-owned units). However, after entering the market economy era, publishing houses generally set up distribution departments (departments) to make the market bigger and stronger. Books have been sold to various sales channels (state-owned, private, etc. ), and "distribution" should be a historic word. Now, many publishing houses no longer simply refer to the department responsible for sales as the "distribution department", but many of them have changed to the "marketing department" and other similar departments that are in line with other industries, and their responsibilities have gradually expanded from the original simple book distribution to some functions in modern marketing concepts such as making marketing plans.
