Sector weight allocation Firstly, calculate the sector weight Composite Sector Sector PPI calculation CSRC Industry PPI calculation Construction (A)Non-metal mineral Composite PPI A Materials, products (Composite PPI B*number of firms metal ore B+ Composite PPI C* number of mining Steel firms C)/( number of firms B + (C)Ferrous metal foundries number of firms C ) and presses 100*（1+YoY (Composite PPI D*number of firms fibres PPI growth Manufacturing D+ Composite PPI E* number of ） Chemicals firms E)/( number of firms D + (E)Chemical material and number of firms E ) products manufacturing average of mining and over three Coal Composite PPI F month dressing annulus (Composite PPI G*number of firms and natural （G）Petroleum growth gas extraction G+ Composite PPI H* number of Oil & Gas rate firms H)/( number of firms G + processing and number of firms H ) refining (Composite PPI I*number of firms I+ metal ore （I）Non-ferrous Nonferrous Composite PPI J* number of firms mining Metals J)/( number of firms I + number of metal firms J ) foundries and presses Note: (1) PPI data is the latest data when rebalancing (2) The industry classification is CSRC standard. Secondly, according to the proportion of categories PPI data, the weight is calculated as: The weigh of I category = PPI value of i category / PPI value of all the category. Index calculation The index is weighted as the following calculation formula: Current Index = Current Total Adjusted Market-Cap / Divisor × Base Level
