Research objective of our study is to find the effect of technology and market dynamism on the business performances by small- and medium-sized enterprises (SME) supporting services. Technology and market dynamism have been introduced as moderating variables, utilisation degree of information provided by SME supporting services was selected as an independent variable and contribution degree to SME business performances such as revenue, export, employment and so on were selected as dependent variables. Structural equation modeling was established to analyse moderating and mediating effects on SME business performances by SME supporting services using Smart PLS programme. The SME supporting services had a direct effect on SME business performances and also indirectly influenced SME business performances via contribution degree to decision-making of SME executives. Technology and market dynamism significantly moderated the effect of decision-making of SME executives on SME business performances. It could be seen that technology and market dynamism had a mediated-moderating effect on SME business performances.

Role of InfoRmatIon In SmeS SuppoRtIng SeRvIceS  441 were analysed to investigate the relationship between two variables such as independent variables versus mediating variables, independent variables versus dependent variables and mediating variables versus dependent variables. The route from information provision in SME supporting services to business performances was clarified by using Baron and Kenny's mediation model. 'information overload occurs when the amount of input to a system exceeds its processing capacity. Decision-makers have fairly limited cognitive processing capacity. Consequently, when information overload occurs, it is likely that a reduction in decision quality will occur' (Speier et al., 1999). From the information overload, it has been difficult for small-and medium-sized enterprise (SME) executives to make decision properly. The well-defined information analysis services need to be provided to improve decision quality of SME executives and contribute to SME business performances such as revenue growth, cost reduction, export growth, employment growth, etc.
