Abstract:

The risk identification and control of major land consolidation projects is important for ensuring their effectiveness. Based on the whole life cycle of land consolidation, we built a social network model on the basis of recognizing the risk of major land consolidation projects and analyzed the relationships and influence of each risk. We found that from the two dimensions of project stage and factor integration, 39 risk factors can be identified according to the risk subject and risk category. Social network analysis showed that risks are closely linked. Maximum bias exists in the lack of communication between government, having the greatest impact on other risks. The highest degree of intermediation is the lack of communication between construction units, having the strongest control with other risks. The highest agent score is the lack of communication between governments, having a dominant position in coordinating the external risks. According to cohesion characteristics and agency characteristics, the lack of communication between construction units is the most influential risk. The control of the top ten key risks in weighting can effectively reduce at least 7. 12% risk value in major land consolidation projects. Improving the multi-party demand expression mechanism, building a multi-dimensional financial security system, strengthening project quality management and fulfilling the evaluation mechanism are feasible methods of controlling risk. It is necessary to strengthen the management of risk in major land consolidation projects.
