本文應用2008中國社會調查資料庫（CGSS2008）實證分析了利用求職層面社會網絡以及日常層面社會網絡對勞動者就業以及薪資水準的影響。在控制了性別、工作經驗、政治面貌、婚姻狀況和受教育年資等因素的情形下，得出結論：求職過程中運用社會網絡幫忙會提高就業表現，但在不同的求職管道中社會網絡發揮的作用並不相同。求職者使用偏人情性的「非正式」管道尋職對薪資有負面影響。但對於這類人，獲得地位高的管理者的幫助仍可以提升薪資，而強、弱聯繫人幫助的效果區別不大。對於利用偏資訊網絡的「正式」管道求職者，管理者的幫助依舊作用明顯，而幫助人為弱聯繫要優於強聯繫。日常社會網絡的維繫對兩類人都同樣重要，網絡的異質性以及同國有部門的聯繫都對薪資有明顯的增加。但「非正式」管道尋職人群的薪資更大程度上可以被社會網絡因素所解釋，「正式」管道人群的薪資表現更多的由人力資本因素決定。由此可見，中國是一個關係主導的社會，勞動者不僅要在求職中動用所有可能的關係幫忙，在日常時仍舊需要不斷保持、擴展自己的社會關係，特別是高質量的關係，以保證能在資源匱乏或受到管制時獲取便利。 / In this paper，we use 2008 China general social survey date,empirically analysis how the social network affect employment performence and income of workers.After controlling for gender、working experience、political affiliation、marital status 、ducation years and other factors，we find that：In job search process，using social networks will help improve the performance，but the role of its are not the same by different job searching methods.Job seekers who use "informal"way，that due to the favor，to get a job，usually will be penalty in income.But for these people,getting the help from high-status managers can still improve wages.For the workers who use "formal"ways to get a job,the social networks mainly provide informations,and the managers' help still important,and the weak ties even better than strong ties.Maintain daily social network are equally important for two types of people.The heterogeneity of networks and the contacts with the state sector can significantly increase the payoff.But "informal"jobseekers' salary can be explained by social network factors in greater extent."Formal" jobseekers' income are more determined by human capital.Thus,we can conclude that China is a relationship driven society,works not only have to spend at all possible guanxi to find a job,but also need to maintain and extend their daily socal network.Especially high quality guanxi,in order to get more benefits。
