简析中高频经济指标与经济增速的联系：以深圳 GDP 增长为例 | Mid-to-High Frequency Economic Indicators and GDP Growth: A Shenzhen Case Study

GDP is a key measure of economic performance, but its quarterly release cycle limits timely tracking. This paper explores the link between mid-to-high frequency indicators and GDP growth, using Shenzhen as a case study. PMI, CCI, and industrial value-added were selected based on data availability and timeliness. Using national-level data to infer local growth proved feasible, especially post-2005. Directional prediction showed moderate results (PMI around 60%), though numerical prediction from limited indicators fell short of expectations due to the complexity of the economic system. Further work on data processing and model refinement is needed.
