The microdistrict theory was developed in the Soviet Union to establish self-contained urban units that compact residential and industrial functions. This allows elaborate social systems to penetrate and control the private domestic realm. According to S. Strumilin, this theory could “promote the purpose of a socialist society by supporting collectivised living for all workers and releasing women from the drudgery of housework”.

In North Korea, the notion of a microdistrict (or "soguyeok") was widely applied as an integrated model for large scale development that was optimised for mass construction. The first model microdistricts were constructed in Hamhung as housing estates. In a typical residential-led microdistrict (see Concept Plan 1), there would be a smaller proportion of public amenities like shops, schools and restaurants 9. To encourage women's participation in order to alleviate labour shortage, women are "freed" from housekeeping through the setting up of childcare centres and food factories, and the provision of benefits like maternity leave with pay, and free schooling 5.

The distribution of industrial versus residential facilities could be inverted to create an alternative microdistrict (see Concept Plan 2). In this case the industry plays the defining role in the microdistrict, with residential facilities and amenities fitted around it. The Kim Jong Suk Textile factory likely belongs to this latter configuration.

微区理论是在由苏联发展的,目的是建立能够包括住宅与工业功能的独立城市。 这使社会主义制度能够渗透和控制私人家庭的互动空间。 根据斯特鲁米林的说法,这一理论 "通过支持所有工人的集体化生活,将妇女从繁重的家务劳动中解放出来,从而促进社会主义社会的目标"。

在朝鲜,微区的概念被广泛应用,成为了大规模开发的总体模式,优化了大规模建设。 咸兴建造了第一个微型示范住宅区。 在以住宅为主导的微型小区里(见概念规划1),商店、学校和餐厅等公共设施所占比例较小9。为了鼓励妇女参与劳动,以缓解劳动力短缺,微区建立了托儿中心和食品工厂等工业设施,使妇女从家务劳动中"解放" 出来5

工业设施与住宅设施的分布可交换,以创建另一类微型区(见概念规划2)。 在这种情况下,厂业在微区中扮演着决定性的角色,其周围安装了住宅设施和便利设施。 金正淑纺织厂应属于第二种结构。
