The transformation of entrepreneurial activity in the conditions of the development of the digital economy and a methodology of assessing its digital security

The innovative way that business is developed in the context of the digitalization of the Ukrainian economy dictates conditions where modernization and the development and strengthening of business positions on an international scale become more and more significant and unavoidable for every enterprise. Therefore, this is subject to detailed control and the implementation of digital security. The purpose of this study is to substantiate and develop theoretical and methodological provisions and scientific and practical recommendations for improving the system of businesses’ economic security in the digital economy. The stages of introduction of digital technologies were considered. This made it possible to trace the chain of development of digitalization in the country: from a sales representative offering modern digital devices to an ordinary consumer using these devices and software in everyday life. Research has shown that the digital revolution is changing business models, manufacturing and competitiveness. Over the past two years, the vast majority of enterprises have been using information and communication technologies. The analysis showed that digital business models tend to differ depending on the size of business structures and technologies. Businesses use ERP systems when they reach a critical level, allowing them to cope with the complexity and significant time, financial resources, and retraining required to implement ERP. Thus, the gap in the distribution of ERP is much larger between the structures of medium and small businesses than between the structures of large and medium businesses. Intersectoral differences in digitization are significant. In knowledge-intensive sectors, enterprises are more intensively using all types of technology, and some aspects of digital transformation are almost complete – for example, the average share of employees with access to connected devices is around 90%, compared to 50% in all sectors. In order to unify the process of studying the conditions in which digital innovations and entrepreneurial activity take place, a methodology is proposed for assessing the country’s economy regarding digital transformation. No significant relationship was found between the level of digitalization and the overall performance of the company. This may be due to the fact that the companies under study are not clearly perceived by specialists and information technology leaders due to the lack of digitalization, and in most cases are not subject to strategic planning. Infrastructure companies are more likely to see tangible results in performance assessments such as improved accuracy and quality. The banking sector will benefit by increasing the flexibility of processes, strengthening their focus on customer needs, increasing sales and the emergence of fundamentally new products. The industrial sector indicates a low return on projects in terms of increased sales and the emergence of new customers, as well as the emergence of fundamentally new products, services and opportunities. A significant relationship between organizational digital culture and the level of digitalization was not identified due to the low level of staff involvement in the digital development project. The digitalization of business processes will give impetus to the total complexity of all professions, on the one hand, freeing up the time of employees to solve more complex and creative tasks. On the other hand, it will significantly increase the requirements for their qualifications. Activities have been developed to support digital security risk management and enterprise resilience.
