**5. Conclusions**

Increased digitalization has led to increased provision of shared services, which is especially noticeable in developing countries due to the relatively low level of income and the tendency to save financial resources without additional expenses for their maintenance.

According to Ukrainian websites engaged in selling shared goods and services, the rental price of goods is less flexible than the sale price of similar interests on the market within the country. As a component of the circular economy, the sharing model promotes not the overproduction of new things but the rational use of those already produced, which can significantly reduce the amount of waste generated at all stages of the product's life cycle. Sharing is one of the factors in establishing a circular economy. The increase in the life span of goods and the enhancement of their social utility can positively affect economic indicators and ecological parameters. They can encourage resource-saving and adoption of the Zero waste concept.

Analysing the range of shared goods, we can see the greatest demand for goods and services with a purchase price of less than 1000 EUR for Ukraine, which indicates the unsatisfactory economic situation of citizens and the use of sharing primarily to save household finances while the environmental effect is not of high priority for the population of Ukraine. When developing scenarios for further development through the example of the furniture company, one has found out that the optimistic system based on the principles of the circular economy has a higher prime cost and a more extended payback period primarily because of marketing losses.

The calculations shown can help develop methodologies to help companies justify raising financial resources for circular economy measures.

The research reveals that the company's lease and subsequent repair and sale or restoration of sharing is more environmentally friendly. It is based on the circular economy principles, waste reduction, resource-saving for production and increase in product life. Due to the adoption of an optimistic model, which is preferred, more environmentally friendly and establishes the principle from simple production of goods to services for maintenance and repair of goods and their further operation, faces higher expenses. Still, it will be more profitable in the long run than in the standard and pessimistic scenarios by creating additional projects, saving resources and ensuring environmental friendliness, which will positively impact public health.
