Information technology is believed to produce considerable influence on all of the five basic elements of an enterprise' s internal control system:(1 )"Horizontalization" of the enterprise' s organizational structure is possible, the control group becomes the best form of the enterprise' s autonomous control and the enterprise's control limit is expanded;(2) The range of risk control is enlarged, which increases the risk of the enterprise staff's involvement in decision-making and meanwhile provides an instrument for risk control;(3) The difficulty and complexity of internal control increases;(4) The enterprise information system gets vulnerable to illegal intervention;(5)The enterprise' s internal control takes the form of man-machine model.

企业内部控制是企业为保护其资产安全，保证信息的完整和正确，促进经营管理政策得以有效实施，提高经营效率，控制经营风险，防止舞弊行为发生，并进而实现企业目标的一项重要的管理制度与方法，它由控制环境、风险评价、控制活动、信息与沟通、监控等相互关联的五个基本要素构成。在信息技术环境下，企业内部控制系统的五个要素构成的框架体系并未发生实质性的改变，但企业信息环境的急剧变化，给企业内部控制带来了新的问题与挑战，影响并改变着企业内部控制要素的具体内容与表现特征。

This chapter, by using the theory of public interests of the government control, control-capture theory, the theoretical model of the government control, the minimum government control theory construed the basic contents covered by the government control, and discussed the interactivity and the nonnegligible effects of the government control and the industrial development model.
