Empirical Study on the Cause of Price Index Change to Warship Maintenance Costs

摘要：

Based on the analysis method in statistics, the serial data of price change index and warship maintenance costs was used to study the influence of price change to warship maintenance costs. The Error Regressive Model was established to analyze the relationship of variables by the statistic analysis and the serial correlation of the data, and further, the dynamic influence was probed by the Variance Decomposition. The empirical result shows that, except the ship A, the price change had the long-term and steady effort to warship maintenance costs; And all the long-term model underestimated the rising range, and the positive short-term adjustment was necessary; Otherwise, in the long sight, the rising of maintenance costs of ship B was mainly caused by itself, but ship C and D was mainly caused by the price change.
