Neural Network Based Transaction Classification System for Chinese Transaction Behavior Analysis

With the rapid development of Chinese economy, it is significant to examine the economic activities in China. Each transaction behavior is recorded by the invoice. The invoice contains the transaction content, the classification of the transaction behavior (in accordance with the Tax Classification and Coding for Commodities and Services issued by the state) and transaction price, etc. Our work uses real mass invoice data collected from Zhejiang Province and conducts a multi-dimensional analysis of Chinese transaction behavior based on transaction behavior classification model. Firstly, we propose a compositional CNN-RNN model with attention mechanism to recommend the corresponding categories of transaction behavior collected from tax invoices. It maps the transaction behavior recorded in the invoice to transaction code in the Tax Classification and Coding for Commodities and Services issued by the state. Preliminary experiments show that the top-one accuracy of classifying transaction behavior achieves 75%. Then, we focus on the quantity distribution of invoice data and draw a conclusion that the major category with larger number of invoice records is more diversified in subdivided categories. After that, we studied the price distribution of various transaction behaviors to discover the difference in price distribution between different industries. Prices in the major categories of goods are more concentrated in the middle or lower prices. We can analyze the regional industrial structure through the price distribution of the industry which makes sense to study the economy of the region from the perspective of industry.
