UDC 69:65.016 ; JEL Classification: D23, L74The purpose: to determine the overall impact of the factors relevant to the construction industry and the impact of additional internal factors of the country's construction industry subjects during the analyzed period. Research Methodology: assessment is possible using an effective, thorough and reliable analysis methodology. Proposed assessing methodology of the effectiveness of strategies development of Ukrainian construction industry enterprises takes into account a comprehensive and wide range of valuation indicators (sales revenue of construction products, volumes of construction products production, market share in accordance with the planned and actual parameters of the development strategy implementation). The following methods were used: - methods of system analysis and synthesis to consider theoretical aspects of the effectiveness of development strategies; - methods of statistical analysis for studying the financial condition of Ukrainian construction enterprises; - methods of economic and mathematical analysis to determine quantitative assessment and evaluation indicators; - formal logic methods for conclusions development and ways to improving the effectiveness of development strategies of Ukrainian construction enterprises. Results: the calculation and evaluation of the effectiveness of the planned (declared) development strategy implementation of the five construction industry enterprises of Ukraine for 2015-2017 were conducted. The estimation procedure of the most significant influence of factors on the level of implementation effectiveness of strategies of the country's construction industry enterprises was given. The presented results of the state and transformations of the implementation effectiveness level of the planned (declared) development strategies allows to form the basic provisions of the formation historiography of this sphere for the specified period. these include: lack of investment in development, despite the need to upgrade the fixed assets and technologies used to implement strategic parameters; insufficient implementation of innovations of construction methods management, waste management, management of energy efficiency of construction products and construction (it is established that only two (SC JSC “BK “Ukrbud” and PJSC “HK “Kyivmiskbud”) are used the innovations and only one enterprise uses effective innovations implementation (SC JSC “BK “Ukrbud”). The most significant influence of factors on the effectiveness level of the strategies implementation of the surveyed enterprises during 2015–2017 was estimated. Scientific novelty: for the first time the determination of the overall impact of the general factors of action relevant to the construction industry and the impact of additional internal factors of the subjects of the countrie's construction industry during the analyzed period is substantiated. It is established that, unlike the existing approach, an assessment of the impact of a set of these factors of development of Ukrainian construction enterprises, which are investigated through their positive or negative effect on the state of effectiveness of the implementation of planned (declared) development strategies. It should be noted that all values of these factors for the individual specified categories were calculated within the framework of this study. It is proved that in order to determine the most significant influence of factors on the effectiveness level of strategies implementation of the studied country's construction enterprises, and their integrated assessment was carried out. Practical value: the presented study allows to estimate the level of internal resistance to the influence of external, general internal (sectoral) and international factors by the largest enterprises of the construction industry of Ukraine during 2015-2017. The investigated results of the factors influence state is a historiography of the strategic development of the subjects of the industry during the specified period, which can be used to compare by parameters of development the counteracting of factor influence for other enterprises in this industry (medium, small, etc.).
