上海，被誉为“现代中国的钥匙”，中西文化在此交汇碰撞，是中国现代化的重要代表。室内设计与人民生活息息相关，特别是住宅室内设计，它体现着人民物质与文化需求的总体水平。民国时期（1912-1949年），上海社会的经济、文化进入一个快速发展的时期，人口不断增长，城市化程度较高，住宅大量兴建。上海住宅及其室内设计，以租界为代表，作为中国城市现代化进程的一部分，也加速了现代转型。 论文系统梳理民国时期上海发行的大量期刊文献，将现代转型中的民国上海住宅的室内设计置于宏观社会经济文化背景中；关注因城市化程度高，人口密集所带来的居住问题与租界营造，为规范建筑建造颁布的建筑章程，以及20世纪二、三十年代成立的两个重要的建筑学术团体——中国建筑师学会与上海市建筑协会。分类型讨论里弄、公寓、花园三种不同住宅，通过个案分析其室内设计的空间布局及设计案例。色彩是住宅室内设计的基调，是烘托住宅室内整体氛围的前提。20世纪初期西方色彩科学理论研究在民国时期传入上海。论文关注民国上海设计师与学者对室内色彩的研究、讨论与传播。民国时期的室内陈设是学界目前较少关注的领域。室内陈设是美化居室的重要手段，也是居住者品位与喜好的体现。论文采用个案研究、对比研究、图像学等方法，对民国时期上海住宅的家具、窗饰、花卉绿植、壁饰等室内常见陈设物品进行分析。中国社会传统思想倡导男主外，女主内。随着女性受教育程度的提高，妇女解放运动的兴起，以及西方家政学的传入，民国期刊积极倡导女性参与居室陈设实践，并出现都市女性参与上海住宅室内设计的案例，论文关注这种社会现象，并梳理相关的期刊、文献、人物与案例，进行专题分析研究。综上所述，论文梳理民国时期上海住宅室内设计在现代转型期间所面临的挑战；总结在中西文化碰撞交融的背景下，上海住宅室内设计实践与理论探索；并分析在满足居住需求的前提下，民国时期上海住宅室内设计丰富的人文内涵与时代特征。
