The presence and effective implementation of the intellectual potential of construction enterprises is important for creating unique competitive advantages as a response to challenges caused by globalization, the era of the knowledge economy, as well as the development of communication and information technologies. The purpose of the study is to provide a comprehensive understanding of the factors that contribute to the development of intellectual capital in construction enterprises;development of an algorithm for thorough response by the enterprise to the action of *** following methods were used: Analysis and synthesis, induction and deduction when studying the variety of determinants of the development of intellectual capital;grouping in the process of classifying determinants;statistical methods in the process of researching the reporting of construction enterprises;systematic approach in the process of forming an algorithm of actions aimed at ensuring effective management of the intellectual capital of construction enterprises;abstraction to generalize research results and outline significant trends in changing indicators that reflect the development of individual components of intellectual capital. In the paper, the determinants of the development of intellectual capital are grouped according to the classification features important for Ukrainian construction *** indicators, the monitoring of which is necessary in the process of implementing a conscious response to the action of the determinants of the development of the intellectual capital of construction enterprises, are studied on the example of Ukrainian construction enterprises.

针对现有文献在数字经济规模的测算方法方面存在的分歧，首先基于国家统计局发布的《数字经济及其核心产业统计分类（2021）》，明确了投入产出表中的部门分类与数字经济核心产业各细分行业的对应关系；然后基于官方发布的投入产出表及投入产出延长表、学者编制的时间序列投入产出表，结合历次经济普查数据，采取将数字经济核心产业各细分行业的增加值按比例从国民经济各行业增加值中剥离出来的做法，测算了中国1981-2020年数字经济核心产业的规模及其各细分行业的占比；并与代表性文献在同口径下进行了比较，验证了测算结果的稳健性。在此基础上，预测了“十四五”时期各年中国数字经济核心产业可能达到的规模及其各细分行业的占比，并对未来数字经济核心产业的发展趋势以及数字经济统计制度建设进行了展望。

Economics World 2014年第4期2卷 215-222页

作者： Yadulla Hasanli Jeyhun Abbasov Cybernetics Institute of Azerbaijan National Academy of Sciences Baku Azerbaijan Central Bank of the Republic of Azerbaijan Baku Azerbaijan

＂Input-output＂ table which was designed for solution of mutual relation （impact） problem is a widely applied tool in the world for conducting economic analysis and forecasting. One of the most important problem of today＇s world is to prevent financial-economic crises in several countries of the world and especially in Eurozone countries where it is still ongoing. Input-output balance tables were prepared by modifying input-output table based on relevant economic indicators of the biggest countries of economy in the world as well as simulations were conducted by designing several balance models （mutual impact of GDP and change in general output of countries, mutual impact of added value and prices, mutual impact of GDP and work places）. Level of coverage of relevant indicators used in analysis on the countries of the world were tested on the basis of statistic methods and assessed. It was identified that, level of confidence of the coverage in designed model on world economy is higher than 95%. These models enable to analyze and forecast possible changes in world economy caused by changes which took place in economic conjecture of other big countries of the world, especially in USA, Japan, Germany, and China. It should be noted that, model＇s system was automatized in EXCEL system with the purpose of simplifying simulations and conducting analysis and increasing efficiency on the usage of models.

This paper, which is to be collocated with international research studies of the historical origins of corporate social responsibility （CSR）, deals with both the theme of CSR itself and the topics related to it through an examination of the key characteristics of the theories of the master in the field of Italian Economia Aziendale, Paolo Emilio Cassandro （1910-2004）, who wrote an impressive number of works on numerous subjects that are of notable current relevance, including the social role of business, the concept of added value, and the role of the social report in the process of providing information for external purposes. Through an analytical-descriptive approach, our work will focus in particular on certain aspects of his life and works, which show beyond doubt the great value of his contribution to the advancement, at both national and international levels, of research into CSR. The main aim of what follows is to highlight not only the innovative nature of Cassandro＇s studies of the subject when compared with other research carried out in Italy in the second half of the 20th century but also how strikingly relevant they are to CSR as a topic for international scholars today.

作者： Manuel Ferreira Rebelo Gilberto Santos Rui Silva Lusiada University Vila Nova de Famalicao Portugal Polytechnic Institute of Cavado and Ave Barcelos Portugal

Nowadays, there exist various standards for individual management systems （MSs）, at least, one for each stakeholder. New ones will be published. An integrated management system （IMS） aims to integrate some or all components of the business into one coherent and efficient MS. Maximizing integration is more and more a strategic priority in that it constitutes an opportunity to eliminate and/or reduce potential factors of destruction of value for the organizations and also to be more competitive and consequently promote its sustainable success. A preliminary investigation was conducted on a Portuguese industrial company which, over the years, has been adopting gradually, in whole or in part, individualized management system standards （MSSs）. A research, through a questionnaire, was performed with the objective to develop, in a real business environment, an adequate and efficient IMS-QES （quality, environment, and safety） model and to potentiate for the future a generic IMS model to integrate other MSSs. The strategy and research methods have taken into consideration the case study. It was obtained a set of relevant conclusions resulting from the statistical analyses of the responses to the survey. Globally, the investigation results, by themselves, justified and prioritized the conception of a model of development of the IMS-QES and consequent definition and validation of a structure of an IMS-QES model, to be implemented at the small- and medium-sized enterprise （SME） where the investigation was conducted.
