This $3000 book (Dictionary of Contemporary Chinese Economics) by Nanjing University has official explanations for every term used in Chinese socialist and Marxist economics, including:

• productive forces
• economic base and superstructure
• value vs money vs price
• circulation of commodities versus circulation of money
• labor theory of value
• primitive accumulation of capital
• socialist market economy
• primary stage of socialism
• China's rural revitalization strategy, and poverty alleviation program
• development, environmental, industrial, financial economics
• dialectical and historical materialism

The book is written by Chinese economists who shepherded China through Reform and Opening Up, so you can be sure that their explanations are accurate, and not the misleading liberal claptrap you usually see around economics

It's so hard to find good official documents that explain Marxist economics, so this book is amazing. This is the best reference I have ever found on it.

Y'all should all download it for reference.
