1996年3月23日臺灣民眾開始經由公民投票選舉方式，推選出全體公民相對多數認可的國家領袖，自此臺灣民主化正式邁入新的里程碑。在民主化的發展上，自1996年至2011年，臺灣共歷經三位民選總統，分別是：1996年的首次民選總統「李登輝先生」、2000年首次政黨輪替的「陳水扁先生」以及2008年再次政黨輪替的「馬英九先生」，確立臺灣以和平方式完成政權移交及朝向民主化國家發展，公民有權決定國家領袖及影響國家未來。 在兩岸關係以及國家定位上，三位前後任總統皆有其所追求的目標，不同時期主政者其所提出的國家定位皆影響著兩岸關係的發展。相對於臺灣國內政治因主政者的輪替，而造成臺灣內部國家定位的改變，中共對臺政策自改革開放後則相對穩定，終極統一臺灣的精神維持不變。因此本論文將以假設中共對臺政策方針基本不變下，臺灣歷任民選總統不同的國家定位對於臺灣國家認同的變遷所造成的影響，以及臺灣國家認同的變遷對於兩岸關係所造成的影響。 On March 23 1996, the citizens of Taiwan selected a relative majority of all citizens recognized national leader through a referendum election, since Taiwan''s democratization has officially entered into a new milestone.
