Agglomeration effects are an essential element of business decision-making on the location of projects, but in the eastern territories of Russia their significance and influence are questioned. The southern industrial belt of Siberia, including the Omsk, Novosibirsk, Tomsk, Kemerovo, Altai and part of the Krasnoyarsk region, has a combination of development characteristics that can contribute to the manifestation of agglomeration forces. The aim of the study was to obtain quantitative estimates of the impact of the agglomeration effects on the development of the region. The study was based on information about enterprises presented in the SPARK-Interfax database for the period 2019–2020. The analysis methods included maps representing the spatial distribution of the average for the municipalities level of output and profit of the enterprises, as well as an econometric analysis of the influence of the factor of remoteness from the regional capital on the performance of the firm. Regression estimates for individual regions confirmed the importance of agglomeration effects either for revenue or for the profitability of enterprises. Average estimates for enterprises of the entire South Siberian macro-region showed a significant contribution of the agglomeration effects to both output and profit, reducing the distance to the regional center by 2 times increases revenue by 1.6%, and profits by about 5.1%. Confirmation of the significance the of agglomeration forces and their positive impact on the economic and financial characteristics of business in the regions of southern Siberia are the arguments in favor of initiating and implementing public and private infrastructure projects that might improve the transport network and reduce barriers for the interaction of enterprises and population

The paper addresses to a spatial analysis of daily prices for 6 types of fruits and vegetables in 81 regions of Russia from January 1, 2019 to March 31, 2022. The study set of information was formed by the Federal Tax Service with extraction data from fiscal registrars; it contains up to 95 332 observations for each type of fruit and vegetable products. Within the indicated data array, we explore the presence of a spatial correlation of prices and their growth rates by assessing the global Moran’s index and local Moran’s indices, in daily, weekly and monthly dynamics. To analyze the presence of cyclic changes in spatial dependencies, we use a correlogram, which was evaluated by various special tests. Our analysis showed that the level of data aggregation (in the form of daily, weekly or monthly values) affects the possibility of interpreting the results. The rate of spatial price change at the regional level usually exceeds one day. At the same time, in certain periods, it can be significantly registered within a week and it shows the synchronism of price changes on monthly data. Different Spatial dependence was revealed in the context of the considered goods types. We revealed the most stable spatial dependences for potatoes. Significant seasonal and weekly cycles of spatial dependence, determined by seasonal price fluctuations, were identified for potatoes. Our findings will be interesting to wide range of people dealing with issues of spatial measurements and problems of interregional interaction, as well as macroeconomic problems of pricing
