Abstract: 【Purpose/significance】Exploring the influential mechanism of ecological allocation of network information resources from
micro perspective, so as to provide reference for improving the structure and function of information ecology and realizing the full shar⁃ing and optimal utilization of network information resources.【Method/process】This study constructs a influencing factor model of net⁃work information resources’ecological allocation effect from three aspects of information resources, information subject and informa⁃tion environment. The analysis of the influencing factors and configuration is conducted by structural equation model and fuzzy-set qualitative comparative analysis based on questionnaire data.【Result/conclusion】Structural equation model analysis indicates that the quantity and quality of network information resources have a positive impact on allocation efficiency and allocation fairness. Informa⁃tion literacy of information subject has a positive impact on allocation efficiency, but has no significant impact on allocation fairness.The adaptability of network system can positively influence allocation efficiency and allocation fairness, but the openness of network system has no significant impact on allocation efficiency. The fsQCA shows that the quantity of information resources, information liter⁃
acy, combination of openness and adaptability of network system are three paths to achieve high allocation efficiency. The quantity of information resources respectively combines with the low information literacy, the adaptability of network system, the quality of infor⁃mation resources and the openness of network system constitute the three paths of high allocation fairness.【Innovation/limitation】This study uses a mixed method to more deeply reveal the influencing factors and structural relationship of ecological allocation of network information resources. And more factors can be considered and time series analysis can be carried out in the future research.
