- Urban land will face high fluvial flood risk against the background of climate change and urban expansion. The effect of urban spatial expansion, instead of densification of assets within existing urban cells, on flood risk has rarely been reported. Here, we project the future flood risk of seven urban agglomerations in China, home to over 750 million people. The inundated urban land areas in the future are projected to be 4 to 19 times that at present. Without considering the urban spatial expansion, the inundated urban land areas will be underestimated by 10-50%. Urban land is more likely to be inundated than non-urban land, and the newly-developed urban land will be inundated more easily than the historical urban land. The results demonstrate the urgency of integrating climate change mitigation, reasonable urban land expansion, and increased flood protection levels to minimize the flood risk in urban land.

- In China, state-owned commercial banks have monopoly position on the banking loan market. This paper constructs a two-stage dynamic game model to analyze the conspiracy in decision-making of bank loans, based on the establishment of relationship lend between SMEs and managers in large banks. Results indicate the existence of an optimal equilibrium as the solution of conspiracy. A revised mathematical model analysis with relaxed assumption shows that: if the state-owned banks have the mastery of large amounts of capital, supervision of SMEs lending are weak, and bank manager has the control of complete information of enterprises, the conspiracy tendencies for both parties will be more obvious. The conspiracy based on relationship lends between banks and enterprises will greatly damage the interests of banks and extrude high-quality SMEs.
