從圍堵危機的角度考量，提高臺灣糧食自給圍並不一定可以強化臺灣的糧食安全保 障。圍堵危機的性質不同於長期戰爭，它是短暫而且通常有充分的時間準備危機的來臨。在 短期間內，準備的手段，除了國內生產外，更效的手段尚包括貿易、儲藏、運輸與通信等。 本文強調，當臺灣的糧食自結率下降時，相對的貿易與儲藏的功能更能發揮效率，更適合於 應付短期圍堵危機所可能產生的糧食安全問題。近年來，臺灣在運輸、通訊、貿易與倉儲的 快速發展，更增強臺灣糧食安全的保障。提高糧食自給率，以應付長期動亂或戰爭所產的糧 荒恐懼是不切實際的想法。因為歷史上，戰爭與糧荒可說是等號的關係。而糧食自率的下降， 提供糧食在貿易、倉儲、運輸、通訊上建立更緊密的各種網路，而這些正是提供臺灣在圍堵 危機下糧食安全更佳的保障。

　　　　　To strengthen Taiwan's food security position by increasing self-sufficiency ratio is doubtful, especially when the country faces siege crisis Siege crisis is not the same as war the lasts several years It is a short run nature, may be few weeks or three moths at most, and usually the country under siege has enough time for preparation before siege occurs Although domestic production seems more relevant to food security, but alternative measures such as trade, storage, transportation, and communication would be more important factors in dealing with siege crisis. Taiwan has improved these alternative measures substantially in recent years and hence has enhanced its food security position It is not a realistic expectation that raising food self-sufficiency ratio could cope food security issue effectively during war time Because, history has evidenced repeatly that war will bring famine A fall of food self-sufficiency ratio provides closer networking environments for food trade, transportation, storage and communication It also implies that food security will be insured further when Taiwan faces siege crisis in the future or when this siege mentality prevails.
