The web search data, which recorded hundreds of Millions of searchers concerns and interests, reflected the trends of their behavior and provided essential data basis for the study of macro-economic issues. This paper established a concept frame based on commodity market and equilibrium price theory, revealed a certain correlation and lead-lag relationship between web search data and consumer price index (CPI). Empirical results indicated that there is a co-integration relationship between web search data and CPI. The model was able to obtain a good fit with CPI. Model fitting is 0.978.
