Models of dependence of GRP growth rates on investments and models with a distributed lag

Currently, the issues of ensuring high growth rates of the gross regional product are relevant, therefore, the paper examines the impact of the growth rate of investments in fixed assets on the growth rate of the gross regional product, taking into account the fact that the return on investment may occur in a few years. In this regard, the paper presents dynamic time series models with a distributed lag, on the basis of which it is possible to characterize changes in time. The object of the study is the Republic of Bashkortostan and its neighboring regions, since it is the development of interregional cooperation of neighboring regions that is most relevant in modern conditions.
