Dynamic Analysis And Influence Factors Of Newcomers' Using Behavior In Information System

Newcomers of information systems are the source of vitality in the implementation of the system.Their attitude towards the system is directly related to the system's use behavior.This not only affects the newcomers' own interests,but also may affect the normal implementation of the information system.Information systems can help companies gain a competitive advantage,but companies often face the risk of failure during the implementation of information systems,and the failure rate of information system implementation is high.In order to help enterprise information systems achieve long-term success,considering that information system implementation is a dynamic process,the factors that affect the use of the system are also changing accordingly.Therefore,this article dynamically analyzes the newcomer's system usage behavior,and explores the impact factors of the newcomer's analysis usage behavior at different stages.In order to reveal the user behavior of the system more comprehensively,this paper analyzes the evolution process of newcomer task network from the new perspective of newcomer,with the help of the concept of user task network,studies the dynamic changes of the user behavior of the system in the task environment,and attempts to explore the causes of newcomer system using the adaptive structure theory and network embedding theory.Based on the information system log data of a shipbuilding enterprise from November 2011 to October 2016,this paper constructs a newcomer task network,analyzes the evolution process of the newcomer task network from the micro and macro level,and probes into the influencing factors that cause the change of the newcomer analysis behavior.The main research conclusions are as follows:(1)The evolution process of newcomer task network is analyzed from macro and maicro levels.From the macro level,through the comprehensive analysis of aggregation coefficient,average shortest path and modularity,it is found that the characteristics of the task network environment of newcomers are composed of decentralized small group aggregation.Combined with the definition of system implementation process by existing scholars,the implementation process of information system is divided into three stages: rapid response stage(SRP),stable adjustment stage and later stage.At last,according to the analysis of the degree distribution,it is found that in the sap stage,the degree distribution appears power-law distribution with tailing phenomenon,which satisfies the scale-free characteristic.From the micro level,with the change of nodes,newcomers' use of the system shows the characteristics of differentiation,they leave after use,intermittent use and continuous use.Through the analysis of node connection,it is found that in the early stage of system implementation,newcomers are relatively independent and scattered,but in the later stage,the newcomers rely more on the guidance of the old users to use the system,and further analysis of the evolution characteristics of the structural hole shows that the newcomers show different degrees of information and control advantages in the process of system implementation.(2)The direct effects of task diversity and system complexity in different implementation stages on newcomers' analysis behaviors are inconsistent.In SRP,task diversity and system complexity both negatively affect newcomer analytical use behavior;in SAP,task diversity positively affects newcomer analytical use behavior while system complexity negatively affects newcomer analytical use behavior;in later stage,task diversity positively affects newcomer analytical use behavior while system complexity has no effect on newcomer analytical use behavior.(3)The regulatory effects of structural holes on task diversity and system complexity in different implementation stages are inconsistent with the results of newcomer analytical use behavior.In SRP,structural holes positively regulate the relationship between task diversity and system complexity with newcomer analytical use behavior;In SAP,structural holes have no moderating effect on the relationship between task diversity and system complexity and newcomer analytical use behavior;in the later stage,structural holes positively regulate the relationship between task diversity and newcomer analytical use behavior,but have no moderating effect on the relationship between system complexity and newcomer analytical use behavior.
