다국어 초록 (Multilingual Abstract)

This study empirically examines that information technology(IT) expenditures in banking industry improve financial performance (i.e., cost reduction, increasing revenue and profit) and market share, an indicator of competitive advantage. It finds that the relationship between IT expenditures and bank`s financial performance or market share is significantly different depending upon informatization level, size and management strategy of sample firms. Main results of this study are as follows: 1) For banks that maintain higher level of informatization. IT expenditures seem to decrease payroll expenses but increase operating expenses, total administrative expense, market share and profitability. 2) The evidence also shows that IT expenditures positively impact on market share and profitability but negatively impact on total expenses for large banks. 3) The positive effect of IT expenditures on market share and profitability is higher for retail banks than whole-sale banks, although IT expenditures increase total expense. The evidence may suggest two important practical implications. First, if banks effectively use electronic banking strategy as means of restructuring to improve competitive advantage, it may reduce payroll expenses and increase market share and profitability as evidence suggested. Second, the results also suggest that in case of promoting super-banking and/or retail banking strategies as means of improving competitive advantage and financial performance, electronic banking strategy (i.e., informatization strategy) should be preceded. Thus, this study provides an evidence to guide directions for restructuring banking industry in Korea.
