GDP Growth Rate Prediction
Application: Shanghai GDP Forecasting
The proposed integrated model was applied to forecast Shanghai's GDP growth rate for 2022-2024. The results demonstrated a closer fit to the actual trajectory of Shanghai's GDP growth compared to models relying solely on traditional statistical data. This highlights the model's practical utility in providing more timely and dynamic insights for regional economic decision-making.
- Leverages real-time social media data.
- Overcomes limitations of traditional statistical data (timeliness, dimensionality).
- Provides dynamic and in-depth insights.
- Supports data-driven decision-making for government departments.

Future Research: Expanding AI in Forecasting
The study highlights three key future directions: expanding data scope to multimodal data (images, audio, video), incorporating high-frequency indicators (subway volume, exchange rates), and deepening large model application for advanced semantic understanding and multi-model coordination. These advancements aim to further improve timeliness, sensitivity, and scope of macroeconomic predictions.
- Integrate multimodal data (images, audio, video).
- Utilize high-frequency indicators (e.g., subway passenger volume).
- Leverage large AI models for advanced semantic understanding.
- Develop collaborative architecture for large model and prediction models.

Your AI Implementation Roadmap
A strategic phased approach to integrate cutting-edge AI for superior macroeconomic insights within your organization.
Phase 1: Data Strategy & Acquisition
Define relevant social media keywords, establish data collection pipelines, and integrate with existing statistical data sources. Focus on cleaning and initial processing.
Phase 2: Advanced Data Processing & Fusion
Implement SimCSE for text vectorization, address missing data with KNN imputation (k=6), and normalize combined datasets. Validate data quality.
Phase 3: Model Development & Training
Construct and train the LSTM neural network model with fused data, tune hyperparameters (e.g., 64 hidden units, 2 layers, 0.15 dropout), and optimize learning rates (0.001 Adam).
Phase 4: Validation & Deployment
Evaluate model performance using MAE and rolling window forecasting. Deploy the model for real-time macroeconomic forecasting and integrate results into decision-making dashboards.
