In the period of transformational conversions of the Ukrainian economy and the entrance of Ukraine into the international globalizing space it is necessary to pay much attention to the problem of creation and the functioning of national network of international transport corridors in Ukraine and their entrance into the international transport system.
The purpose of the article is to analyse the influence of the road transport infrastructure on regional development on the 'powiat' (administrative district) - (NUTS 3 level) - in Poland. In particular it researches the impact of the road network endowment on the volume of production and the productivity of production factors. Authors have carried out the analysis using the econometric methods. They estimated the parameters of the three models based on the Cobb-Douglas specification of the production function. In the first one the influence of the road density on the production sold (in PLN) in private sector in Poland (aggregated on the 'powiats' level) was analyzed. In another two: the effect of the road endowment in creating the productivity of the classical production factors - capital and labour in the private sectors was questioned. According to the results of the first model, the coefficient at the variable 'density of the road network' is positive, and so flexibility of production in relation to road infrastructure is positive. 1% increase in the length of roads increases the production value by approx. 0.056%. This result shows positive implications of having a good road network endowment for formation of the value of sold production of enterprises at the level of administrative districts (powiats) in Poland. Results of the second estimation show positive, comparatively high and statistically significant elasticity of fixed capital productivity amounting to 0.31% in relation to the road infrastructure endowment per unit of this capital. However the third estimation shows, in turn, negative, amounting to - 0.27%, and statistically important flexibility of productivity of workers in relation to the size of road infrastructure per worker. The results of research made suit the general character of conclusions from studies on influence of transportation infrastructure on economy - in particular, due to their ambiguity. All models were estimated on the basis of identical panel data and brought rather different, although not conflicting results. The influence of the road factor, for which density of the network was assumed here, was positive and statistically important. The research also confirmed, in Polish conditions, the thesis described in the literature about growing productivity of private capital owing to infrastructural investments. In turn, negative flexibility of productivity of labour in relation to road infrastructure can mean that road investments are not directly reflected in employment growth in the place of carrying out the investment.

A significant impact on the multifunctional development of rural areas is the so-called transport accessibility. This applies mainly to the capabilities and reach the pace of the in-habitants of the so-called areas peripheral to the main economic centers of the province. The research includes analysis of the availability of transport in quantitative and qualitative as-pects, which was defined for the purposes of research. Quantity and quality of transport in-frastructure, the number of connections, length and travel time to the most important eco-nomic centers were taken into consideration. Analysis of transport availability sets the target application development, which is to determine the key investment priorities for the next programming periods of transport infrastructure development of the Warmia and Mazury province.
This paper analyses wider economic and social impacts of motorways. It analyses the development of socioeconomic variables in the Slovak LAU 1 regions in the period 1997 – 2016. Difference in differences, panel regression with fixed effects, and synthetic control methods (SCM) are applied so as to identify potential long-run effects of motorways on regional economies and societies. The paper finds positive effects of motorways on wages, the number of firms, and internal migration. An SCM is the best procedure for measuring wider economic benefits of motorways when the number of treated units is low or there is only one treated unit.
The aim of the article is to verify the spatial development of Kyrgyzstan and Vietnam in relation to their socio-economic development. Having used coefficient of variation and rank-size rule methods basing on the data gained from ETM+ Landsat images analysis it was stated that Kyrgyzstan's settlement and transport networks are theoretically underdeveloped in relation to the country's level of development and that in Vietnam they are much better developed than it could be expected. The environment conditions and past and recent politics could significantly modify the spatial development in the countries analysed.
