摘　　要：自然地理单元是支撑区域经济、社会和文化发展的基本要素,行政区划常常造成相对独立的自然地理单元的人为割裂,产生空间阻碍效应,影响区域可持续发展。流域水资源作为一种流动性的自然资源要素,贯穿于流域上下游行政区之间,区划隔离效应更加明显。文章以新安江流域为研究对象,综合采用经济增长收敛模型和改进的Barro回归分析方法,探讨新安江流域行政区经济非均衡发展特征和行政边界效应,揭示不同时段的行政边界效应演化规律。研究表明:①新安江流域行政区经济发展差距总体呈现"先收敛、后发散"的演化特征,尚未形成一致σ收敛性,经济非均衡性呈现"先缓解、后加剧"的"U"型变化态势。经济发展水平较低的空间单元发展速度相对较快,朝着自身稳态的经济发展水平收敛,具有显著的绝对β收敛特征,各行政区间经济发展的非均衡性趋于消除。②新安江流域经济增长存在典型的行政边界效应和结构性特征,行政边界影响了经济发展差异的缩小速度,限制了流域经济一体化。③省际行政边界对流域经济一体化发展产生了显著的屏蔽效应,表现出差异化的演化过程,非均衡性的省际行政边界效应从2005—2011年的0.0023上升到2012—2017年的0.0244,增速为961%。The natural geographical unit is the basic element to support the development of regional economic,social and cultural. Administrative division often results in the artificial separation of relatively independent natural geographical units and spatial barrier effects,affecting regional sustainable development. As a kind of fluid natural resource element,the river basin water resources runs through the upstream and downstream administrative regions of river basin, and the partition isolation effect is more obvious. Taking the Xin’an River basin as the research object,this paper comprehensively adopts the economic growth convergence model and the improved Barro regression analysis method to explore the characteristics of economy non-equilibrium development and administrative border effect of the administrative region withinthe Xin’an River basin,and reveals the evolution laws of administrative border effects in different time periods. The research indicates that: 1) The economic development gap in the Xin’an River basin administrative region generally shows the evolutionary characteristic of "first convergence and then divergence", and has not yet formed a consistent σconvergence. Economy non-equilibrium presents a "U" change trend of "first easing,then intensifying". The spatial unit with low economic development level is at a relatively fast speed,converging to the level of economic stability of their own steady state with significant absolute β-convergence characteristics. The economy non-equilibrium of each administrative region tends to be eliminated. 2) The economic growth in the Xin’an River basin has obvious administrative border effects and typical structural characteristics. The administrative border hinders the reduction speed of the economic development difference,which directly affects the economic integration development of the river basin.3) The inter-provincial administrative border has a significant shielding effect on the economic integration development of the river basin, showing a dif
