5 我國可編程序控制器發展中的問題及對策
目前我國的可編程序控制器的發展主要面臨著三大問題。一是技術層面上的，在國際上可編程序控制器迅速發展的形勢下，我國還沒有具有自主知識產權，能夠參與國際競爭的可編程序控制器產品，原因主要在於我國的整個基礎工業還有差距，如芯片制造、模具加工等方面限制了我們的發展。二是競爭層面上的，實際上也是一個經濟競爭的問題。現在95%的國內市場由外國的可編程序控制器產品所佔領，中、大型可編程序控制器中，幾乎全部由國外幾大公司壟斷，隨著我國使用可編程序控制器領域的不斷擴大，市場越來越大，然而國外幾大公司幾乎每年都會針對市場推出新的產品，一旦人們使用了新的產品後，他們就會逐漸的提高產品市場價格，沒有我國自己的自主知識產權的產品，在經濟競爭中就只能處於被動。三是市場秩序層面上的，隨著我國改革開放的不斷深入，特別是加入WTO後，我國巨大的市場份額的吸引了國外的大公司，他們開拓市場的方法都是採用大範圍建立代理銷售渠道，每個公司的分銷商、係統集成商都會有數十家，甚至上百家之多，造成了我國的分銷商、係統集成商之間的激烈競爭，而這些無序的競爭為國際大公司分而治之、獲取穩定的高額利潤創造條件。
