All the methods that can bring enterprises to talk can be used, such as inviting investment, exhibitions, intermediaries, networks, advertisements and so on. However, according to my personal experience for many years, not all methods will be effective, and sometimes I can't even see a shadow after spending money. We should make a careful evaluation according to the actual situation. If we don't have a special understanding of this aspect, I will recommend a book: The Practical Raiders of Investment Promotion in Industrial Parks, which is the only book in the industrial real estate industry that systematically introduces and guides investment promotion.
