同许多社会领域里的范畴和概念一样,工人阶级也是个发展变化的历史范畴。例如,我国工人阶级,在不同的历史条件下,尤其在改革开放的社会转型时期,其内涵、外延几乎时时刻刻都在发生着明显地变化。因此,适时地研究我国当代工人阶级的内涵和外延变化的新情况,并对其进行科学地界定,是个值得高度重视的应用课题。 Like many areas and concepts in the social field, the working class is also a historical area of ​​development and change. For example, under the different historical conditions, especially during the social transformation period of reform and opening up, the working class in our country has undergone a noticeable change in its connotation and extension almost at all times and in all places. Therefore, timely study of the new situation of the connotation and the change of the extension of the current working class in our country and the scientific definition of the working class are a topic worthy of attention.
