近些年来，煤矿企业安全事故时有发生，严重制约着煤矿企业效益的提高。在煤矿企业中员工的安全行为及绩效水平对企业安全生产效率提高起着至关重要的作用；影响煤矿企业员工绩效的因素众多，除了传统的知识技能、工作特征、环境因素等还与员工的社会支持与社会交往的状况有关，煤矿企业员工由于工作环境等原因日常工作与生活中的交往能力都处于较低水平；想要进一步提高煤矿企业的效益，提高员工绩效水平及构建和谐的企业安全文化与和谐社会仍有许多需要完善的地方，本文基于这样的现实背景，展开对煤矿企业员工的社会支持网络状况及对其绩效影响的研究。 首先，本文在阅读大量国内外相关文献的基础上，综述了前人在员工绩效影响因素方面、社会支持网络和社会网络与绩效方面的理论及成果，发现社会支持网络视角的研究空白，确定本文的研究目标；其次，通过2011年11月“煤矿企业员工调查问卷”抽样调查，获得煤矿企业员工日常工作与生活中社会支持网络情况的信息及绩效水平信息；再次，通过运用个人社会网络分析方法与多元回归分析方法对多元线性回归模型及假设进行检验。研究发现以下几点： （1）员工的社会支持网络特征中，网络规模较大、关系类型较丰富，其中同事和朋友占据较大的比重，性别与年龄的趋同性高，异质性低，学历的趋同性与异质性不明显，关系连带强度相对较高； （2）社会支持网络特征中有代表数量特征的网络规模与代表质量特征的关系连带强度。员工与网络成员关系连带强度的频度强对员工的任务绩效有正向的影响；网络规模越大和关系连带强度的频度越强都对员工关系绩效的人际促进有正向影响。网络规模大，员工在工作生活中有更多的网络成员可以请教、合作与交往，其关系绩效水平就高；网络关系连带强度越高，员工的心理压力得到了缓解，具有较高的归属感与合作意识，更愿意高频率的与网络成员互动，不但增进彼此的感情，获得良好的工作沟通，还促使员工努力工作，更好的完成安全生产任务； （3）社会支持网络不但对员工的任务绩效有直接的影响，而且还通过关系绩效间接地影响员工的任务绩效，即关系绩效的人际促进在关系强度的频度对任务绩效的影响过程中起中介作用。 总之，本文在理论与实证研究的基础上，系统地展开了煤矿企业员工社会支持网络及对其绩效的影响研究，指出了社会支持网络对煤矿企业员工绩效的重要意义，提出提高煤矿企业员工的安全生产绩效，扩大其社会支持与交往范围及能力的各项政策建议。

In recent years, coal enterprise safety accident happen from time to tome, and constrain the coal enterprise efficiency. In coal mine enterprises the employees behavior and performance level of safety in production play the most important role in enterprise efficiency improving; Many factors affect the performance of the employee of the coal mine enterprises, in addition to the traditional knowledge and skills, working characteristics, environmental factors there also are the social support staff and social communication about the situation. Because of coal mine enterprise employees’ work environment, their daily work and lives of interaction ability in the low level; In order to further improve the benefit of the coal mine enterprises, and improve the performance level and the construction of the harmonious enterprise safety culture and the harmonious society there are still many needs to perfect place. This study based on the realistic background of the coal mine enterprises staff puts forward the social support network status and their impact on the performance of the employees. First of all, on a large amount of related literature at home and abroad, and on the basis of summarizing the predecessors' the achievement of the respect and experience in performance influence factors, the thesis find out the social support network perspective research blank, and determine the target; Second, daily work and life of social support network information and performance level of the coal mine employees was collected by a field survey and interviews in November 2011, providing powerful data support for further study and inspection empirical model; Again, the thesis use personal social network analysis methods and multiple regression analysis method to test empirical model and the hypotheses. The thesis found that the following points: (1) The coal mine employees have large network size; Relationship type is abundant, with colleagues and friends occupying larger proportion; Gender and age is of high network homophily, and low heterogeneity, meanwhile homophily and heterogeneity of degree is not obvious; The relationship tie strength is relative higher; (2)The social support network features of the network size and tie strength has positive impact on employees' task performance and contextual performance. The larger the network, more network members employees can consult, then the performance level is higher; when network tie strength is higher, the employee's psychological pressure has been eased, with high sense of belonging and sense of cooperation, more willing to better complete the safety production tasks; (3) The social support network not only directly impact on employees' task performance, but also through the relationship performance indirectly influence employees' task performance. When the employee's interpersonal facilitation and job devotion level is high, this two respects of social support network of the safety influence task performance more remarkably. In short, on the basis of theory and empirical study, through coal mine enterprise employees social support network and its influence for the performance, the thesis points out that the social support network of the coal mine employees play the important role in its performance, further improve coal mine employee safety production performance, and give the scope of policy suggestions for expanding its social support and communication ability.
