Whether the orientation of safety investment is reasonable has direct effects on safety economic benefit. According to the specialty type of safety work, safety investment is compartmentalized into six orientation investments： safety technology investment, industrial hygiene technology investment, off-set facilities investment, safety propaganda and education investment, labor protection and accident handling investment, and repair investment. Based on these types, grey relation degrees between all safety orientation investment and safety output are calculated and compared by utilizing grey relational analysis; weight grades of all safety orientation investments are decided. Thus, the orientation of safety investment is optimized. The result of this demonstration shows that this method has high veracity and overcomes the shortages of other system analytical methods. Moreover, the operability of this method is strong and it is convenient, simple and applicable.
