雖然省內(nèi)硼礦資源豐富，但硼酸工業(yè)卻沒(méi)有形成區(qū)域性行業(yè)發(fā)展優(yōu)勢(shì)，缺乏整體規(guī)劃。在青海硼礦資源產(chǎn)地之一海西州，開采企業(yè)受地方保護(hù)主義的影響，硼礦只供給海西州內(nèi)的企業(yè)。西寧市以及其他地區(qū)的硼酸生產(chǎn)企業(yè)只能從西藏等地購(gòu)買原料，運(yùn)費(fèi)增加不少，無(wú)形中加大了企業(yè)的生產(chǎn)成本。另外在價(jià)格上，在大柴旦等靠近硼礦生產(chǎn)基地的地方，硼酸價(jià)格比市場(chǎng)價(jià)低300-500元/噸，影響了行業(yè)優(yōu)勢(shì)的形成。
目前青海硼礦資源還存在許多不穩(wěn)定因素，由于開采技術(shù)等諸多因素的制約，硼礦質(zhì)量時(shí)好時(shí)壞，使得硼酸生產(chǎn)企業(yè)對(duì)產(chǎn)品質(zhì)量不好把握；在量的方面，由于硼礦資源集中在海西州大、小柴旦湖硼礦等地區(qū)，采礦單位硼礦供應(yīng)的不穩(wěn)定，直接影響到其他地區(qū)的硼酸生產(chǎn)企業(yè)。因此青海地區(qū)硼酸工業(yè)區(qū)域優(yōu)勢(shì)整合顯得尤為重要。
