- On the whole, Xinjiang is still at the stage of a developing dual economy, that is to say, it is still in the middle of the transition from the extremely unbalanced dual economy to an increasingly mature one. However, since the beginning of the Eighth Five-Year Plan period, with growing investment from the central finance in the development of strategic resources in Xinjiang, especially with the development of the three big oil fields and the petrochemical industry in Xinjiang, there have been new trends in the entire regional economic structure and industrial structure in particular. The regional economic structure has been optimi.zed and upgraded amidst constant readjustment efforts, the proportion of industry continues to grow on the existing basis, now exceeding 60%. The industrial structure is moving in the direction of heavy chemical industry-led development. The output value of heavy industries centered on oil and petro- chemical industries accounts for over 50% of the total industrial output value and keeps rising.
