How to improve the mode of procurement process, and find a clear point of time under good purchase, good nickel price is an important issue. We interviews domestic nickel raw material used in nickel metal products manufacturing company, through interviews with the company's internal management and procurement staff. We find that, even if the company owns a procurement process, but the final decision of exact time of nickel raw material procurement point sometimes rely on procurement personnel’s experience. Thus, when faced with the case of corporate purchasing department personnel changes, the experience is not really inheritance, easily misjudge purchase point in time, resulting in the procurement costs of the phenomenon. This study hopes to construct a new procurement process model which is a better objective than the old model. Reference interrelated purchasing patterns, and identify the impact of raw material price fluctuations of nickel economic indicators from the literature, and then use statistical model, Granger causality test to identify four key economic indicators, respectively LME stocks followed the price of gold, USD exchange rate and Brent crude oil prices, indicators for statistical test to determine the causal relationship, then to establish a new procurement model. The results found that, the new procurement model can save 1.46% of the cost price, making the procurement process more efficient.
