201July 4. The Catalogue of Industries Prohibited and Restricted by the State is an important policy document for Beijing to control "big city diseases", promote reduction and upgrading, and promote intensive and efficient development. The release date is July 20 14, which is not to restrict development, but to "slim down and keep fit" and promote the capital to achieve high-quality development. The aim is to strictly control the increment of non-capital functions from the source, and closely combine with the stock adjustment measures such as general manufacturing and the withdrawal of polluting enterprises that do not meet the functional positioning of the capital, help Beijing transform and develop, and continuously optimize and upgrade the functions of the capital.
