由於平台(Platform)經濟近年來的興起，平台嚴然已成為了世代推動買賣中不可欠缺的商業主流主流模式之一，許多傳統與新創產業藉由平台的建立，而展開了新的商業經營模式。
平台帶來了快速發展的經濟型態，以網際網路的電子信息技術作為基礎，幫助交易雙方能夠不受時間與空間的限制，高效的促進了經濟行為的發展。此外，透過網路與平台可以讓操作雙方只要透過任何可連網的行動裝置，便可以在有別於傳統範疇的市場空間進行買賣、採購或比價，除了提升供需兩端的效率且更為方便，其中隱含的交易成本更是大幅下降。
回到供需雙方本身，由於平台建置後會有固定的通用規則，整合不同文化、國籍的消費者以及電腦的溝通系統，潛在消費者的數量也將大幅增加。價值鏈的縮短將會讓供應商更接近顧客，同時有準則的平臺也能夠幫助雙方建立互信的基礎，提升雙邊資訊的時效精確性與即時性，塑造更為長遠的合作機會，這些都是利用了「平台(Platform)」的力量。
本研究係以鋼結構產業為研究對象，希望透過分析、策略、設計科學研究法來解析鋼結構市場產業線性生產模式的交易買賣，以對鋼結構的了解與訪談平台參與者對鋼結構平台的理解與期待，逐步針對平台的經濟模式特性分析、規劃並設計出符合鋼結構平台商業模式，希望能夠提供在發展鋼結構平台的途徑上跟隨者有效的營運原型。藉由著平台力量使其鋼結構產業符合市場需求且企業過度擴張，此研究結合商業模式中的關鍵活動，為鋼結構平台生產者與消費者利用價值主張規劃出「平台的服務」、「鋼結構平台推廣」、「平台的契約管理」，以利使用平台解決雙邊交易買賣的媒合、改善鋼結構業市場能見度、快速尋找合適鋼構廠、交期合適、品質合宜、價格實惠之最佳產品供應商。
透過網路平台的建設，消費者能夠快速瀏覽、比較並做出採購與選擇。從賣家的產品展示到買家的購買下單，價值鏈中的進料後勤、生產、出貨、消費等都將衍生出相關的服務，舉凡品牌塑造、客戶諮詢、異業合作甚至第三方的金流與支付等，都是巨大的價值創造機會。我們唯有持續延伸觸角、積極測試、深入了解平台經濟的邏輯規模經濟，不去盲目複製他人的商業模式或其他平台，才能針對服務鋼構廠、消費者（顧客）雙邊客群，使該平台長期獲利與成長，並能永續擴及業界服務對象，發展出最適合台灣國情的平台企業。

Due to the rise of the platform economy in recent years, the platform has become one of the mainstream business models that are indispensable in the promotion of transactions for generations. Many traditional and new industries have launched new business operations through the establishment of the platforms model.
The platform has brought about a fast-developing economy. Based on the electronic information technology of the Internet, it helps both parties to the transaction to be free from the constraints of time and space, and efficiently promotes the development of economic behavior. In addition, through the network and the platform, both operators can trade, purchase, and compare prices in a market space different from the traditional category as long as they use any mobile device that can be connected to the Internet. The implied transaction costs have dropped significantly.
Back to the supply and demand sides themselves, since the platform will have fixed general rules after the establishment, and integrate consumers of different cultures, nationalities, and computer communication systems, the number of potential consumers will also increase significantly. The shortening of the value chain will bring suppliers closer to customers. At the same time, a platform with rules can also help the two sides build a foundation of mutual trust, improve the timeliness accuracy and bilateral information, and create longer-term cooperation opportunities, which is the power of "Platform".
This research takes the steel structure industry as the research object and hopes to analyze the transaction of the linear production mode of the steel structure market industry through the analysis, strategy, and design science research method, so as to understand the steel structure and interview the participants of the platform on the steel structure platform. Understand and expect, and gradually analyze, plan and design a business model that conforms to the steel structure platform according to the characteristics of the platform’s economic model, hoping to provide an effective operation prototype that follows the development of the steel structure platform. With the power of the platform, its steel structure industry is in line with market demand and the enterprises are over-expanded. This study combines the key activities in the business model to plan the use of value propositions for steel structure platform producers and consumers. Structural platform promotion", "platform contract management", to use the platform to solve the matching of bilateral transactions, improve the market visibility of the steel structure industry, quickly find the right steel structure factory, the best delivery time, reasonable quality, and affordable price product supplier.
Through the construction of online platforms, consumers can quickly browse, compare, and make purchases and choices. From the seller's product display to the buyer's purchase order, related services will be derived from the logistics, production, shipment, and consumption in the value chain, such as brand building, customer consultation, cross-industry cooperation, and even third-party services. Cash flow and payment, etc., are huge opportunities for value creation. Only by continuously extending our tentacles, actively testing, and deeply understanding the logical economies of scale of the platform economy, and not blindly copying other people's business models or other platforms, can we target the two-sided customer base of serving steel structure plants and consumers (customers) and make this platform a reality. Also, long-term profit and growth, can lead us to expand to the industry's service targets, and develop a platform enterprise that is most suitable for Taiwan's national conditions.
