Based on the payments and settlement system, the influence of the topology of capital flow networks on the extra short-term liquidity demand is investigated. Through modelling the circulating mechanism of liquidity in a network, its different influencing factors are analysed. The factors relating to the strength of nodes and leakage of liquidity that influences the liquidity demands of real-time settlements are studied from the perspective of both the system and members, using different simulation methods. The results show that strength will lead the member’s liquidity demand to increase but the strength distribution will lead the system’s liquidity demand to decrease, in cases with no leakage effect or unchanged leakage effect. The liquidity demand of the entire system is positive compared to the amount of leakage effect but uncorrelated to the distribution of the leakage effect among members, if the effect of strength distribution is unchanged. If the effects of strength, strength distribution and leakage are changed together, the latter is the dominant factor that influences the liquidity demand of both system and members. The above findings are useful for the management and supervision of short-term liquidity demand in complex financial systems, and for liquidity risk management and liquidity rescue policymaking.

Building entrepreneurial companies is associated with taking actions to enable their general development, leading to application of innovative solutions, both in technology and management. Modern economy and pervasive crisis force entrepreneurs to search for alternative means for supporting the progress in order to be able to fight for customers against ‘foreign countries of cheaper production’ and, at the same time, to not being forced to use "drastic" methods of reducing production costs. This paper presents the already existing solutions that are not fully used in Polish reality, which are the network structures (clusters) that have beneficial economic impact and build integrated supply chains. The author is taking a theoretical attempt to connect concept of supply chains and clusters. Consolidation will relieve the individual companies and thereby will create opportunities to take new - common – actions, which together will create entrepreneurial network structure and bring individual benefits.
