This paper is in regards to the analysis of how much the government’s support in the form of providing consulting services contributes to financial outcomes and to the analysis of the gap of performances among the types of consulting services. We verified the statistical significance of our hypothesis through SAS9.4 and SPSS 22, conducting comparative analysis of the business growth and profitability based on the yearly balance sheets and income statements of 44 corporations which government supports and 150 corporations which are for comparison. The data is gained from CRETOP, Korea Enterprise Data, and the testing model is chosen as the business of support center for corporate growth, which is a customized supporting business of the Ministry of Trade, Industry, and Energy.
