Abstract: As one of the world's leading research universities, Massachusetts Institute of Technology (MIT) has driven outstanding innovation since its foundation in 1861. In addition to management and organizational factors, MIT provides a spatial campus environment that stimulates and nurtures interdisciplinary collaboration. In particular, the large and interconnected scientific research buildings effectively promote exchanges and innovation between different disciplines. This study reveals the spatial campus characteristics of MIT that promote interdisciplinary collaboration and innovation, and provides references for campus planning and construction of research-oriented universities aimed at interdisciplinary innovation in China.
　　The original planning and construction documents for MIT in different historical periods were collected, and the construction background, planning concepts, and specific construction responses in different periods were summarized. Moreover, a qualitative analysis of MIT's planning and construction measures in response to the changing needs of disciplines in different periods was carried out. The evolutionary laws of scientific research building spaces at MIT Cambridge were summarized systematically. Meanwhile, the evolutionary characteristics of scientific research building spaces at MIT Cambridge were elaborated via quantitative analysis based on statistical analysis of student population, land area, scientific research building area, and connectivity of scientific research buildings.
　　Based on this review of the centennial construction processes used for the scientific research building spaces of MIT Cambridge, the development process can be divided into three periods: the early relocation construction period (1916-1960) in the context of layout difficulties of Boston campus; the expansion period (1961-2000) in the context of adapting to disciplinary development one century since its foundation; and the partial construction period (after 2001) which is focuses on innovation since the 21st Century. During different periods, MIT has always adhered to its mission of promoting interdisciplinary collaboration and innovation and made corresponding campus planning guidelines and construction responses according to social development and the changing needs of disciplines. Scientific research building spaces at MIT present a spatial morphological evolutionary law of "integration, extension, and darning" from the integrated layout with the goal of "all disciplines under one roof" in the background of relocation in 1916, to the extended growth of "expanding the scientific research building network according to disciplinary development" after the 100th anniversary, and then to the darning regeneration according to the goal of "creating more connections for different disciplines" in the 21st Century. 
　　The increasing density and connection of scientific research building spaces are the most essential characteristics used by MIT to promote interdisciplinary collaboration and innovation. On this basis, the high-efficiency scientific research building network significantly strengthens connections between different disciplines. The remarkable achievements of MIT demonstrate the significance and value of its campus spaces in promoting interdisciplinary collaboration and innovation.
