Abstract:

Based on the data of the CSI 300 stock index futures and the CSI 300 stock index spot markets, the trading competition relationships between the stock index futures and spot markets are tested with the Lotka-Volterra model, and the price discovery relationships between the stock index futures and spot markets are tested with the VAR, VECM, PT and IS model. Furthermore, the relationships between trading competition and price discovery are studied. The conclusions are drawn as follows:there are significant time-varying characteristics in both trading competition and price discovery between the CSI 300 stock index futures and spot markets, the trading competition is positively correlated with the price discovery, and the dynamic trading competition can explain the time-varying price discovery between the CSI 300 stock index futures and spot markets.

Key words: stock index futures, stock index spot, trading competition, price discovery
