其次，通過對影響小麥國際競爭力的主要因素的國際比較發現：中國小麥單位產品生產成本具有明顯優勢，但由於較高的流通費用，導致在價格上不具有優勢；小麥質量較差、品質不穩定是導致中國小麥國際競爭力較低的主要因素；生產要素中化肥和勞動力投入對中國小麥生產力水平的影響程度較小，而種子、灌溉和機械投入對小麥生產力水平的的影響程度較大，因此小麥生產投入要以增加種子、灌溉和機械的投入為主，代替大量的化肥和勞動力投入，進一步降低小麥單位產品成本，增強中國小麥國際競爭力；中國小麥的上下游輔助產業（包括品種資源、生產資料和加工業）的國際競爭力較弱，發展較為滯后；中國小麥生產者的組織化程度較低嚴重製約了中國小麥質量的提高、流通費用的降低和加工業的發展；小麥生產經營活動本身的特點決定了在充分發揮市場機製作用的基礎上，必須通過政府的宏觀調控來克服其市場機制的失靈，保障市場機制有效運行，但通過國際比較研究發現：中國政府在生產者支持、市場體系建設和國際貿易政策上對小麥的支持水平較低，與提高中國小麥國際競爭力的要求有較大差距，尤其是較低的生產者支持水平和市場體系建設程度制約了中國小麥國際競爭力的提高。It is mandatory to prevent the reverse flow of fire protection system substances, i. e., glycerin wetting agents, stagnant water and water of non - potable quality from being pumped or siphoned into the potable water supply
