China's Regional GDP Estimate Research With Statistical Method

In the whole national economy accounting system, the region GDP reflects the comprehensive economic development level, and can quantify regional economic operation conditions. According to China's current economic accounting system, central and local do business accounting at different level. The national bureau of statistics according masters the basic data of GDP and independent accounting data, but not for local GDP data weighted summary. Consequently, in promoting benefits the summary of area GDP is far above the national GDP, and the gap is wider and wider. Therefore, how to improve the regional GDP accounting system and solve the data gap is an unavoidable problem. According to introducing, in recent years, the national bureau of statistics has been studying directly accounting provincial GDP way.Based on the condition of our country, I put forward three kinds of regional GDP estimates statistical methods: distribution method, Geary - Stark output estimation, Chow - Lin method. Distribution method and output estimation is belonged to "top-down" estimation method. Chow - Lin approach is one of methods for China's regional GDP with inheritance level. The estimation results were compared with the official data, and found that the gap between our estimation results and the official data deviation was small. So it can be used as a high frequency data for regional economic analysis and prediction. Through analysis and verification, these three methods for the national unified accounting regional GDP figures have some considerable value.
