A Concise History of Chinese Economic Thought by Hu Jichuang is a book about pre-modern Chinese philosophers' take on the economy. It's less about the actual economy of pre-modern China (each dynasty has their own unique economic policy and some of the longer ones like the Han dynasty went through multiple economic policies) and more about how Chinese philosophers thought the economy ought to be arranged.

Here's also some Wikipedia articles about pre-modern China's economy. Some of them are pretty long:
