【摘要】 在欧洲政治空间分化重组加剧的趋势下，议题竞争在欧洲政党竞选中的作用日益凸显。随着近年来移民和难民所引发的争议持续蔓延，欧洲政治空间中的选民偏好分布朝着利于右翼民粹政党的方向变化，反移民的右翼民粹主义政党在选举中不断取得突破。对此，左翼政党出现了分化。以丹麦社会民主党和德国萨拉·瓦根克内希特联盟为代表的左翼政党在移民等社会文化议题上转向保守，以左翼保守的立场与右翼民粹政党争夺选民。左翼保守路线虽能吸引右翼民粹政党的部分选民，但也可能将一部分传统支持者推向更左翼的政党，增加政党分裂的风险。从长远来看，左翼保守路线在实践中仍需进一步调整与平衡，以适应复杂多变的政治环境和选民需求。更多还原

【Abstract】 Under the trend of intensifying differentiation and restructuring of political space in Europe,issue competition plays an increasingly prominent role in European party elections.With the ongoing controversy surrounding immigration and refugees in recent years,voter preferences within the European political space have shifted in ways that favor right-wing populist parties.Consequently,anti-immigrant right-wing populist parties continuously make breakthroughs in elections.In response,left-wing parties have become divided.The left-wing parties,represented by the Danish Social Democratic Party and the German BSW,have adopted more conservative positions on social and cultural issues such as immigration,in order to compete with right-wing populist parties for voter support.Although this conservative approach can attract some voters from the rightwing populist parties,it may also push some traditional supporters towards more left-wing parties and,thereby,increase the risk of party splits.In the long run,the left-wing conservative line still needs to be further adjusted and balanced in practice to adapt to the complex and changing political environment and voter preferences.更多还原
