中文摘要：

为了能够适应互联网经济对中小企业的渗透和冲击，中小企业自身必须构建相应的网络化平台，以提高企业自身的效益和竞争能力。但是如何测量和描述中小企业网络化平台构建中IT投入与产出要素以及两者之间的作用机理，一直是国内外相关领域的研究者和实践者所关心的重要问题。文章构建了基于认知视角的IT投入-产出概念模型，并运用结构方程模型进行了实证分析，结果表明中小企业网络化平台构建中IT投入的不同要素对网络化平台下企业不同产出构面的影响具有差异性。该焉千究结果进一步完善了IT投入与产出的相关理论，并对中小企业网络化平台建设具有一定的实践意义。

英文摘要：

In order to adapt to the big impact of internet eeonomv on the small and medium-sized enterprises, small and me- dium-sized enterprises must ennstruct the corresponding internal networked platform to improve their own benefit and compet- itiveness, lint how to measure and describe the indicators of IT input antt output, and the impact mechanism between the lwo, have been an important issue in the related field for both domestic and fureign researchers as well as practitioners. Build- ing an [T input-output conceptual model based on the engnitive perspective, this study applies structural equation model to make an empirical analysis. The resuhs show that different IT inputs of networked platform have different impacts on different enterprise outputs. The stud）, resuhs further improve the relevant theory, of IT input - output, and has a certain practical sig- nifieanee to the construction of networked platform for small and medium-sized enterprises.
