The development gap measured by per capita income itself implies a difference in the structure of resource endowments, that is, developed regions have relatively rich capital elements, which has a comparative advantage in capital-intensive industries; while relatively less developed regions have rich labor. And the comparative advantage of low production costs. The difference in resource endowment structure between the eastern, central, and western regions can undoubtedly become an opportunity for economic development in the central and western regions to catch up. The following statement is inconsistent with the text. ['Differences in resource endowments in different regions have advantages and disadvantages.', 'Relatively lack of labor in developed regions.', 'Midwest can take advantage of abundant labor.', 'Capital-intensive industries are mostly concentrated in the eastern region.']
