The STEM field has contributed significantly to the development of society because its findings result in new technology, which gives people more efficient tools and methods for a better standard of living. Postsecondary institutions have trained STEM field graduates through advanced curricula and learning environments. Compared to other academic fields, STEM requires more monetary support for research from the institution or the government because STEM research often requires expensive equipment installation or the introduction of new technologies. This paper overviews institutional support for STEM education and research by the regime of recent U.S. governments and examines the characteristics of R&D (research and development) expenditure. The results indicate that the R&D expenditures of the STEM field show continuous support for the different type of institutions, regardless of governments over time. However, they have tried to diversify the R&D investment by the type of R&D field and institutional type. Even though the government has tried to increase the total size of R&D expenditure through various resources, they still need to consider the equity and diversity issues for even further R&D investment strategies. A further research direction would search for the detailed action and strategies to support the STEM field according to their types of support or expectation.

STEM领域为社会发展做出了巨大贡献，因为它的发现催生了新技术，从而为人们提供了更有效的工具和方法，以改善人们的生活水平。大专院校已经通过高级课程和学习环境对STEM领域的毕业生进行了培训。与其他学术领域相比，STEM需要机构或政府为研究提供更多的资金支持，因为STEM研究通常需要昂贵的设备安装或采用新技术。本文概述了美国最近政府对STEM教育和研究的机构支持，并考察了R＆D（研究与开发）支出的特征。结果表明，R＆STEM领域的D支出显示了对不同类型机构的持续支持，而与政府无关。但是，他们试图按照研发领域的类型和机构的类型来分散研发投资。尽管政府已尝试通过各种资源来增加研发支出的总规模，但他们仍需要考虑公平性和多样性问题，以制定进一步的研发投资策略。进一步的研究方向将根据其支持或期望的类型，寻找支持STEM领域的详细行动和策略。尽管政府已尝试通过各种资源来增加研发支出的总规模，但他们仍需要考虑公平性和多样性问题，以制定进一步的研发投资策略。进一步的研究方向将根据其支持或期望的类型，寻找支持STEM领域的详细行动和策略。尽管政府已尝试通过各种资源来增加研发支出的总规模，但他们仍需要考虑公平性和多样性问题，以制定进一步的研发投资策略。进一步的研究方向将根据其支持或期望的类型，寻找支持STEM领域的详细行动和策略。
