北洋集团作为近代中国政治舞台上的一支重要势力，曾长期执掌民国政权，对近代中国社会的发展产生了重要影响。王士珍作为袁世凯练兵时期“小站班底”的重要成员，在北洋集团创立发展的过程中起到了重要作用。他与北洋集团的关系也经历了从“合”到“离”的曲折过程。

王士珍与北洋集团关系的变化和北洋集团权力结构的演变密不可分。北洋集团权力结构的改变削弱了王士珍在集团内的决策权与领导作用，使两者间关系出现松动。王士珍自身的性格不利于他建立自己的派系，对他与北洋集团关系的发展起到了很大影响。民国建立后，随着北洋集团的迅速扩张，集团内的派系化趋势日益明显。由于缺乏派系力量支持，王士珍只能依靠与袁世凯的私人关系来巩固自身的权力地位，沦为北洋集团名义上的“元老”。袁世凯野心的膨胀和北洋集团内各派系的相互倾轧，使王士珍产生了淡出北洋集团的想法，两者间关系就此转向。王士珍反对清帝退位的态度以及参政意愿的减弱，进一步加剧了他脱离北洋集团的倾向。

北洋集团权力结构的演变产生了广泛而深远的影响。对王士珍而言，权力结构的改变削弱了他在北洋集团内的决策权力与领导作用。王士珍不仅失去了在北洋集团中的话语权，还在北洋集团的派系争端中进退失据，最终与北洋集团“分道扬镳”。对北洋集团自身而言，前两次权力结构的变化，推动了北洋集团的迅猛发展；但第三次权力结构的剧变，则成为北洋集团走向分裂的重要推手。对清末民初的政局而言，权力结构的演变使北洋集团一度成为清末势力最盛的军事政治集团，在一定程度上决定着清末政局的发展走向。民国建立后，北洋集团因权力结构的剧变走向分裂，直、皖、奉三系并立，使民初政局走向军阀割据的局面。

As an important force on the political stage of modern China, Yuan Shikai Group was in charge of the regime of the Republic of China for a long time and had an important impact on the development of modern Chinese society. Wang Shizhen, as an important member of Yuan Shikai Group, played an important role in the establishment and development of Yuan Shikai Group. The development of his relationship with Yuan Shikai Group also experienced a tortuous process.

The changes in the relationship between Wang Shizhen and the Yuan Shikai Group are inseparable from the evolution of the power structure of the Yuan Shikai Group. The changes in the power structure of the Yuan Shikai Group have weakened Wang Shizhen's decision-making and leadership roles within the group, thereby loosening the relationship between the two. After the establishment of the Republic of China, with the rapid expansion of the Yuan Shikai Group, the trend of factionalism within the group became increasingly obvious. This trend gave Wang Shizhen the idea of fading out of the Yuan Shikai Group, and the relationship between the two changed accordingly. In addition, Wang Shizhen's attitude against the abdication of the Qing emperor and his weak willingness to participate in politics further intensified his tendency to break away from the Yuan Shikai Group.

The evolution of the power structure of the Yuan Shikai Group had a wide and far-reaching impact. For Wang Shizhen, the change in power structure has weakened his decision-making and leadership role within the Yuan Shikai Group. Wang Shizhen not only lost the right to speak, but also lost ground in the factional disputes of the Yuan Shikai Group, and finally "parted ways" with the Yuan Shikai Group. For the Yuan Shikai Group itself, the previous two changes in the power structure had a very positive impact and strongly promoted the rapid development of the Yuan Shikai Group. However, the third upheaval in the power structure played a negative hindering role, and in fact became an important driving force behind the split of the Yuan Shikai Group. For the political situation in the early Republic of China, the evolution of the power structure made the Yuan Shikai Group become the most powerful military and political group which changed the development trend of the political situation in the late Qing Dynasty. After the founding of the Republic of China, the Yuan Shikai Group split due to drastic changes in the power structure. The juxtaposition of the three warlords made the political situation in the early Republic of China go to the situation of warlord separatism.
