數字化是指通過信息技術、網絡技術、通訊技術實現物理世界與虛擬世界的融通，創造聚焦于產品、生產與性能等各環節的數字化雙胞胎應用，將價值鏈上各個孤立的過程無縫連接，通過數據雙向流動與閉環反饋，實現物理世界持續優化。在汽車、電子電器、機械加工、航空航天、紡織、石油石化、制藥和食品飲料等行業，數字化已經打造出一個又一個價值可量化的案例。

中國航天科工集團旗下的貴州航天電器的產品是航天飛船，載人潛艇的“神經”。工廠每個月超過6000個批次的訂單中70%都在10件以下，是典型的“小批量、多品種、定制化”需求驅動。數字化改造讓貴州航天電器生產效率預計提升50%，一個智能制造車間的產線即可輕松應對超過10萬種不同型譜連接器產品的柔性混線生產。而2008年成立的廣州明珞汽車裝備有限公司，則通過數字化將汽車零部件生產線從編程/調試到落地達產所需的時間，由通常的6-9個月縮短到了10天，實現根本的轉變。截至2018財年，西門子已經為數十個行業的數百家中國企業提供了數字化企業解決方案，在行業內樹立了一座又一座燈塔。

這些企業的數字化轉型也證明了一種可能：中國企業可以從制造業價值鏈下游向中上游轉移，劃出更美的微笑曲線。當然，中國工業整體水平的提升僅憑燈塔企業還遠遠不夠。如何將這些企業的成功經驗從點及線，由線及面完成橫向和縱向傳導，惠及龐大的制造業生態圈？

數字化轉型規�；�落地的路徑已經形成

工業企業之所以轉型難以成功或遲遲邁不出第一步，企業管理、組織架構與職能設置無法有效推進相關工作是重要因素，這一現狀從“數字化企業評估模型”的結果中也得到印證。很多企業沒有意識到，數字化轉型是一項CEO工程。數字化轉型是貫穿從戰略，組織到運營各個環節的全方面、多維度改造和升級。轉型之初需要企業CEO以前瞻思維，帶領核心團隊為企業制定數字化轉型戰略，并自上而下逐級推進。企業管理層的參與和支持是轉型成功的重要保障。
現狀評估、項目咨詢、實施、運維和數據增值服務組合打造數字化落地的路線圖。現狀評估，項目咨詢基于不同維度對企業所處現狀進行分析量化，并基于此給出定制化建議，以縮短轉型周期，把控轉型風險；針對企業數字化需求差異選擇相應的實施方案，讓數字化項目順利落地；人工智能與專業知識的融合，提高工藝預測性分析的準確性，為工業提供數據增值服務。專業的數字化咨詢與規劃是數字化轉型成功的先決條件與必要環節。

技術創新為中國工業領域數字化轉型鋪平道路。豐富的工業硬件和軟件產品使得提高生產柔性與生產力，開發新的商業模式成為可能。工業5G、區塊鏈、人工智能、邊緣計算、工業云等技術在工業制造場景中的應用，將為工業帶來深刻的變革，為高質量發展添薪續力。
