半個世紀以來，中國的威脅一直是我國「國家安全」意涵中最主要甚至是唯一的焦點，因此可以說「國家安全」意涵是與軍事安全概念一致的。國家安全的威脅，不僅是來自外部的各種挑戰，還包括了來自內部的天然因素與人為因素的威脅，殆無疑義。921大地震、桃芝颱風造成嚴重傷亡與財產損失，就是例證。國內的安全維護，顯然必須兼顧非軍事面的安全戰略研究、設計、宣傳與執行，才能達成全面性的安全保障。因此，建立全面綜合性安全觀念，乃是不論政府與民間，必須確立的基本共識與觀念，亦是我國邁入21世紀所必須積極著手的準備。然而，當前對我國安全深具威脅的因素中，反而非軍事性因素居多，值得深究。 因此本論文研究側重於中國運用非軍事手段之方式，破壞我國重大設施之國家安全面向為主要探討範圍。並將進一步探討：中國對我可能採取之戰爭型態、影響國家安全之重大設施現況、中共利用政府採購管道進行超限作戰、國內重大設施應有之防護作為等問題，探討的重大設施著重在與民生關係緊密的公共設施，包含(電力、自來水、交通、電信、科學園區、機場、港口、公路、鐵路)等，中國對我使用非軍事手段方面除經濟貿易、環境、能源、族群衝突、民主化發展、毒品與犯罪、恐怖主義、以及疾病傳染等等外，最可能從介入此類重大公共工程設施之防護以進行秘密活動，伺機安裝引爆裝置，並使全台各重要據點所預置之破壞因子同時發作，致使國內救災體系整個癱瘓、民生丕變、金融交易停滯、高科技產業停擺、並形成一陣社會恐慌、社會失序、終致形成無政府狀態；值此同時，中國即以維護國內秩序之名義接收政權，國際團體及友邦無法介入支援或救助。對內完成統一大業，對外宣示一個中國，順理成章地以達到以非軍事手段替代軍事行動所產生之最低成本換取最高效益。 / Since the past half century, the threat of China has been the most important spotlight in "national security". Therefore, it is the same concept with both of national security and military safety. The threat of the national security is including not only the various challenges that come from the exterior but also the natural factor of the inner part and the threat of the artificial factors. It is doubtless that the 921 heavy earthquakes and the Typhoon Torajis cause serious dead, injured and properties lost, are a series of illustration. The domestic security safeguards must look after both sides of the safe strategy research, design and publicize and carry out obviously in the parts of non- military. So we can reach the comprehensive security guarantee eventually. Therefore, establish overall synthesizes safety concepts are our goal to exceed into 21 centuries must begin actively of preparation; in spite of the government and civilian. This thesis research lays emphasis on making use of the non-military means breaking our country’s public facilities by China. Also I will further inquire into: What kind of war type will be adopted by China? How about the current conditions of domestic public facilities? China probably makes use of the governmental procurement to carry on super limit's battling. What kinds of protection we should take in action on regarding public facilities. The major public facilities which I focus on are people's livelihood. It will contain(electric power, the resource of water, transportation, telecommunication, science-based industrial park, airport, port, highway, railroad) etc., In addition to economy trading, environment, energy, ethnicity conflict, democratization development, drug and crime, terrorism, and diseases infecting the etc., the most possible of China is using the non-military means to get involved in breaking major public facilities in order to carry on the secret activity, wait for an opportunity to install an exploding device, and make each important spot prepare to place of the breakage factor goes into action meanwhile. So that It would cause domestic disaster response system whole paralyze, people's livelihood largely change, the finance trade stagnate, high-tech industry lockout, become a social dismay and lose the preface, eventually with the result that formation anarchy appearance; meanwhile, China namely with safeguard the name of the domestic order to receive the political power. And then the international group and allied countries can't get involved the support or salvages. China will claims to have completed to unify the whole country in the inner part and claims to have one China to all foreign country. At last, China will reach to act for the military action with the non- military means to exchange the highest benefit the lowest cost of creation.
