随着人口红利消失、劳动力成本上升，我国制造业的低成本优势正在逐步丧失。劳动力短缺、成本增加、产能过剩及经济的疲软制约了中国制造业的发展。据国家统计局公布的数据显示，2015年我国规模以上工业增加值比上年增长6.1%，我国工业增速已由过去10%以上的高速转向10%以下的中高速水平。面对种种压力，自动化、智能化已经成为了我国工业发展的必然趋势。

工业自动化涉及面广、产业链长，国内市场近万亿。据德国工业4.0工作组统计，2012年中国自动化市场规模已达8000亿元，以29%的占比。在自动化程度提升和存量市场改造的双重驱动下，2015年工业自动控制系统装置制造行业市场规模超过3500亿元。

整个工业自动化行业的产业链中，上游为原材料，主要包括电子元器件、电力电子器件和钣金结构件等。位居中游的则是智能控制系统，下游是应用行业，包括电力、冶金、电梯、机械等行业的应用。

智能控制系统位于整个产业链的中游，其又可被分为三个层次，即控制层、驱动层和执行层。控制层实现对任务的分析、处理和分配，如PLC、DCS等;驱动层将控制层的任务进行解码，变成能被电机、阀门等能够识别的信号，如变频器和伺服驱动器等;执行层则执行相应的任务，包括电机、阀门等。
