In China, the Non-Manufacturing purchasing managers index survey is based on data collected from a representative panel of 1200 enterprises from the non-manufacturing sector. The survey includes ten questions on business activity, new orders, new export orders, in hand orders index, stock, intermediate input price, subscription price, employment, supplier delivery time, and business activities expectation. For each question, the diffusion index is calculated. As there’s no integrated PMI, the business activity index is usually used to reflect the overall changes in non-manufacturing sector. A PMI reading above 50 percent indicates expansion from the previous month, while below 50 indicates contraction.
