The four seasons was spent 2007 up to now, PPI by 3% the left and right sides rises continuously, achieved in August 2008 10.1% , and CPI is in after the portion reached the high point of 8.7% in Feburary 2008 all the way be issued to lower levels, was only in August 2008 4.9% , current and both the difference between achieves 5.2 percent. Prospective CPI and PPI walk along situation general how to change, its have He Ying to ring each other, it is CPI follows PPI up, still be PPI follows CPI is down, become the topic that at present the market pays close attention to very.
Length of be confined to, the similarities and differences that CPI and PPI composition discuss only here takes the mutual effect of situation to its.

1, of CPI and PPI form already across has difference again

The main content of CPI statistic includes equipment of food, dress, family and things, Medical Protection things, traffic and communication tool, recreation to teach culture articles for use, live, the project of Wu of kimono of 8 kinds of big commodity such as service project, OK also and wraparound for food, service and industrial consumable 3 kinds big, do not include investment to taste with asset project. The main content of PPI statistic includes industrial business to make work all sorts of products of all units are mixed beyond this enterprise the product that sells the dweller is used at the life to consume directly, OK also and wraparound produce a material to go up (contain industry of excavate course of study, raw material, treatment industry again) with means of subsistence (contain food, dress, general commodity, durable consumer goods again) two kinds big.

Of CPI and PPI form already across has difference again. Main show is alternate sex: The means of subsistence that 30% is consume finally to be used at the dweller is made an appointment with in PPI, there is 50% to be industrial consumable about in CPI. Main show is otherness: There is 70% to be manufacturing data about in PPI, among them the sources of energy, raw material holds weight very big, but in CPI the weight in forming is relatively lesser; There is 50% to be tasted for food and service about in CPI, its are formed in CPI in weight is very great, but in PPI the weight in forming is relatively lesser. This kind forms the similarities and differences that go up, both to research the effect between is very main. Across will be brought about both and mutual conduct, fluctuant direction shows consistency; What alien likelihood brings about both and fluctuant direction to go up is abhorrent.

2, structural across will be brought about both and mutual conduct, fluctuant direction shows consistency

PPI basically passes CPI to be not provision part to the conduction of CPI. Part of CPI blame provision by industrial consumable kimono Wu is tasted form (release index of blame food price only regularly as a result of statistical bureau, and do not release industrial consumable and service to taste price index, when accordingly we are studying PPI is conducted to CPI, can use only be not food price index and cannot use index of more accurate industrial consumable price) . Because PPI is the upper reaches of consumable of industry of part of CPI blame provision (cost) , consequently the change of PPI can be brought to CPI to be not the change with food price occurrence same way. For example, the government was mixed on November 1, 2007 went up twice on June 20, 2008 moved finished product oil (reach electric power) the price, bring about that month PPI relatively on the month has respectively 1.2 with 1.6 percent jump litre, accordingly, price of CPI blame food has respectively 0.3 with 0.2 percent jump litre.
