三是作為科研型的工控企業(yè)，由于規(guī)模小和專(zhuān)業(yè)分散，缺乏國(guó)內(nèi)統(tǒng)一標(biāo)準(zhǔn)的硬件和基礎(chǔ)軟件支撐，單打獨(dú)斗，形不成規(guī)模。

　　四是受外資控制與擠壓，競(jìng)爭(zhēng)能力差。我國(guó)一些企業(yè)曾經(jīng)自主開(kāi)發(fā)PLC硬件平臺(tái)，但產(chǎn)品剛有眉目，跨國(guó)公司立即降價(jià)。由于PLC系統(tǒng)是技術(shù)密集型的成熟產(chǎn)品，本國(guó)產(chǎn)品初次面世，性能與價(jià)格都缺乏競(jìng)爭(zhēng)優(yōu)勢(shì)。加上缺乏國(guó)家政策支持，在市場(chǎng)上根本無(wú)法立足，陷入了“市場(chǎng)信譽(yù)度低—缺乏實(shí)踐與改進(jìn)機(jī)會(huì)—市場(chǎng)信譽(yù)進(jìn)一步降低"的惡性循環(huán)。

　　五是產(chǎn)學(xué)研結(jié)合的現(xiàn)實(shí)困境：國(guó)家工業(yè)管理機(jī)構(gòu)多次變更，一些共性技術(shù)研究所改企業(yè)，原有的研究進(jìn)程中斷，技術(shù)積累流失或老化。
