In recent years, Chinese high-tech enterprises have been experiencing a period of rapid development. Their scale and quantity have surpassed the figures of some developed countries in the world, and their share in the modern market structure has also increased. Discussing the characteristics of managing high-tech enterprises and managerial measures can not only help enhance the core competitiveness of these enterprises and establish their competitive advantages but also play a positive role in promoting market economy reforms. In the presented study, the author identifies the peculiarities of internal management in Chinese high-tech enterprises. Additionally, the article highlights issues in the management of high-tech enterprises and proposes measures for the improvement of management within this sector of the economy.

There are many disagreements and uncertainties among global land use/land cover (LULC) products, which make it unsuitable to apply these products directly to a specific region. In this study, Enhanced Vegetation Index (EVI) time-series data from the Moderate Resolution Imaging Spectroradiometer (MODIS) with 250 m spatial resolution, combining with geographic features, were used for LULC classification in the Qilian Mountains, northwest China. The authors tested the Random Forest (RF), the Classification and Regression Tree (CART), and the Support Vector Machine (SVM) classifiers. Their final classification product was also compared with 3 global LULC maps. The results showed that (1) topographic information could improve the classification results to some extent when they were integrated with spectral information in complex mountain regions; (2) the classification results using an RF classifier reached the highest overall accuracy (88.84%); (3) there was consistency with homogenous classes between our classification result and the 3 LULC products, but inconsistency with heterogeneous classes; and (4) the overall accuracy of this study was improved about 10% compared with the 3 LULC products. Therefore, this classification product is more suitable than global LULC products when considering complex terrain factors in mountain regions.

The purpose of the present research paper is to make a comprehensive analysis of the Russian foreign policy activities in terms of potential risks and possible consequences of termination, suspension of transnational companies’ activities for the Russian economy. The foreign policy of the Russian Federation makes it possible to set due priorities, define proper formats and set the course for the entire foreign policy of the state, which undoubtedly requires proper organisational and legal institutionalisation. This is why exploring the operation of transnational companies in Russia is extremely important in the current geopolitical environment which is presently being formed with a focus on the sanctions-related pressure against our state on the part of unfriendly countries. The present essay considers the statistical data on foreign multinationals that have left Russia and the measures taken by the Russian government towards adaptation and designing a due economic policy course in the conditions of market economy. The research brought the authors to a substantiated conclusion that foreign policy activities are directly and closely connected with the work of transnational corporations; therefore, the competent internal policy of the Russian Federation will enable the society and corporate entities to adapt to the new realities and to pursue the desired foreign policy activities in the country’s interests, avoiding pressure from unfriendly countries.

In recent years, in order to adapt to the situation of rapid economic and social development, my country’s power supply companies have invested large-scale funds to build distribution networks, and upgraded urban and rural power grids, effectively supporting the rapid growth of power demand and the reliability of power supply. Continuous improvement of power quality. While the scale of investment in the distribution network continues to remain high, problems such as focusing on investment and neglecting revenue, focusing on project establishment and neglecting management also exist to varying degrees. Therefore, reasonably predicting the scale of investment in the distribution network and improving the lean management level of the investment and construction of the distribution network have become key issues that power supply companies need to solve. This paper takes my country’s municipal power supply companies as the research object, combines the actual business development of the company’s distribution network investment planning, and fully considers the impact of the company’s power supply district management and the level of cost differences on the investment scale of the distribution network, and builds a fit on this basis. The distribution network investment planning forecast model of the actual business work of the enterprise guides the municipal power supply enterprises to improve the lean management level of the distribution network investment and construction.

The construction of transmission line in Tibet high altitude area has the characteristics of low pressure, low oxygen and low temperature. In the special environmental condition, the transmission line construction equipment with engine as the power source is highly effective, which affects the efficiency and safety of construction[1].The experimental study on engineering mechanical industry plateau transmission line is still in the blank stage,thus relying on the Tibet networking project selects 5 different high altitude test points to plateau 500kV transmission line construction commonly used types of pullers, tensioners and powered winch as an object of study to carry out the typical construction equipment energy efficiency test of field measurements effective output power equipment in different altitude environment from the perspective of practical application and analysis of law and effect mechanism of falling equipment.
