英文摘要：

This paper predicts the quota and the volume of transactions of non-hydro renewable energy for the five provinces in the northwest region, and establishes the model and the corresponding method of the economic evaluation for the trans- regional and trans-provincial renewable energy trading under the quota system. The paper analyzes the main target markets for Xinjiang, Gansu and Qinghai renewable energy bases for the trans-regional, trans-provincial trade, and finally puts forward relevant policy suggestions such as subsidies for renewable energy transmission, using the average purchasing price as the settlement price of renewable energy power generation for hydropower-rich provinces.
