This book consists of three sections: the first section is the theory system of Unified Economics that I proposed as a pioneer. This theory system currently contains a total of about 30 theories. Unified economics unified microeconomics, medium-sized economics and macroeconomics together. Unified economics achieves the touchability and calculability of economic reality as advocated by Beizhan school of thought. Unified economics analyzed various properties of regional economy comprehensively, and established a more complete and national economic evaluation system with uniqueness. The second section mainly includes my elaboration on the election finance system. The third section mainly includes my elaborations on other economic issues, such as: currency finance economy, real estate economy, and so on.
