Abstract: Under the background of “Silk Road Economic Zone”, China and Central Asian trade have become the hot topic.This paper selects the panel data of trade between China and 31 countries from 1995 to 2014, using the stochastic frontier gravity model to study the export trade efficiency and trade potential of China and Kazakhstan.Results showed that: although Kazakhstan’s export trade efficiency in each year is on the rise, average efficiency of 0.214, export trade efficiency is still low, export potential is larger, the average export trade to expand the space for the 245.18%, shows that China and Kazakhstan’s foreign trade still has a lot of upside.Therefore,we present policy recommendations with exploring the export potential as the aim.

Key words: Trade Efficiency, Trade Potential, Stochastic Frontier Gravity Mode, China and Kazakhstan
