To examine the economic performance of industrial investments from the view of structure is conducive to evaluate properly the allocations of resources among industries and within the industry, and to provide the optimal path and feasible countermeasures based on the current situation of investments. On the basis of selecting and constructing four indexes about the efficiency coefficient of investment, ratio of tax revenue growth, growth rate of GDP and growth rate of employment, this article analyses empirically the impacts of three industrial investments on the indexes by the use of gray relational degree method, contrasts and evaluates the economic performance of industrial investments, and points out the main problems and the adjustment direction in the current industrial investments.
