11 In the past, the development of the eastern region was facing a shortage of economy, developing products, developing production, and investing in projects. It is basically a short-term positioning, and there is a broad space for growth. At present, the development of the western region is facing a sharp drop in external demand and the slow growth in domestic demand. The trend of deflation is obvious, and the production capacity is relatively surplus. According to this passage we can draw the view:. ['The joint development of the eastern and western regions can make the economy prosperous.', 'The economic development difficulties in the eastern region are significantly smaller than in the western region.', 'The connotation and model of economic development in the western region will be very different from those in the eastern region.', 'The western development will directly affect the economic development of the eastern region, and the eastern economy needs to be repositioned.']
