The paper studies the relationship between the regional core competitiveness and TFP, and analyzes the impact on the regional core competition force changes in total factor productivity. Based on the theoretical analysis, using Stochastic Frontier Analysis (SFA) and Transcendental Logarithmic Production Function, the paper constitutes the main elements of the regional core competitiveness into the efficiency equation. The research on the core competitiveness of China"s 31 provinces shows that the core competitiveness is reflected as changes in total factor productivity.
