  1. This dissertation aims to probe into the institutional changes and institutional clashes between the enlarging european union and the central & eastern european countries ( ceecs ), as well as to construct a tentative theoretical innovation to account for institutional interactions between them. supported by political neo - institutionalism and borrowing institutional concepts from nobel prize - winner douglas north, the dissertation is set against a background of the dual process of institutional expansion by the eu and active institutional convergence on the ceecs " own accords. starting from the positive and negative impacts triggered by eu enlargement on both the eu ' s and the ceecs " political, governance and economic institutions, the dissertation carries out a systematic study of the partial adjustments and comprehensive reforms on the part of the eu, as well as of the europeanized transformation of the domestic institutions in the accession countries

    本文以新制度主義政治學為理論支點，以歐盟通過東擴實現制度擴張及中東歐向歐盟制度主動趨同的進程為背景，以東擴引發的制度變遷和制度對撞為研究對象，從分析考察東擴進程對于雙方政治權力制度和經濟治理制度的雙向沖擊及正負面影響入手，系統研究了歐盟東擴引發的歐盟制度局部調整與全面改革、及中東歐新成員國國內制度的歐洲化轉軌之雙重進程，分析總結出東擴制度互動的規律、模式與渠道，並在此基礎上構築了一種解釋轉型國家與超國家機構之間制度互動的實驗性理論模型「錮囚鋒理論」 ，從理論高度上對現實規律進行歸納。
