摘要

隨著電腦資訊化發展蓬勃，電子商務的模式也推行更加廣泛，政府與民間企業漸漸導入電子化採購，營造廠的採購交易也漸漸地從傳統現場採購轉型至電子化採購。雖然電子化採購打破了時間與空間之限制、簡化作業流程、降低採購成本、增進採購效率，然而在資料儲存與交換等過程中仍是透過中心化的伺服器參與，易遭受駭客攻擊、內部人員的共謀或伺服器的損壞，降低了競標商使用的意願度，成為了電子化採購發展與推廣的阻礙與擔憂。
為此，本研究針對營造廠之基本採購程序進行電子化需求分析，據以設計營造廠之採購智能合約，進而以以太坊(MetaMask)為區塊鏈執行環境，並利用Remix進行智能合約之開發及部署，嘗試建立一個以區塊鏈為交易核心的營造廠採購交易平台，藉以展示區塊鏈技術應用於營造廠實際需求之可行性。
從目前之開發成果來看，區塊鏈技術確可導入營造廠採購交易與包商管理平台，並利用其公開性、難以竄改、去中心化等特性，提供營造廠與包商招標、領投標與開決標之程序於系統上操作，對於招標資訊與往後的記錄調閱保證資料得真實性，另防範投標商之投標文件再開標之前被竄改的可能性使得採購資訊更公開、更透明。

With the rising and flourishing of computer information, the model of E-commerce has become more widely implemented. The government and private enterprises have gradually introduced electronic procurement, and the procurement transactions of the construction company have gradually transformed from traditional on-site procurement to electronic procurement. Although electronic procurement breaks the limitation of time and space, simplifies the operating procedures, reduces the cost of procurement, and improves the efficiency of procurement, it still participates in the process of data storage and exchange through a centralized server, which is vulnerable to hacker attacks, internal collusion of personnel or damage to servers. The collusion reduces the willingness of bidders to use it, and becomes an obstacle and concern for the development and promotion of electronic procurement.
For this reason, this research analyzes the requirements of the construction company with the basic electronic procurement procedures to design the construction company's procurement smart contract by using Ethereum (MetaMask) as the blockchain execution environment and using Remix to develop smart contracts and deployment. In order to demonstrate the feasibility of applying blockchain technology to the actual needs of the construction company, try to establish the construction company procurement transaction platform with blockchain as the core of the transaction.
Judging from the development results, blockchain technology can indeed be introduced into the construction company procurement transaction platform by using its characteristics of openness, difficulty to tamper, and decentralization to provide the construction company and contractors to operate on the platform in the bidding process and review the tender information ensuring the authenticity. In addition, it prevents the possibility of tampering with bidders' bidding documents before opening the bid, making the procurement information more open and transparent.
