In this paper, we examine a number of indices used for measuring comparative advantages of a country in international trade for a good and propose the new net comparative advantage index that has several strong features. First, it reflects net trade, and that's why it is more theoretically grounded than indices calculated only from export data. Second, it is consistent with Kunimoto (1977) theoretical framework that is highly appreciated among trade economists. Third, it is not totally focused on a single commodity (that is, it takes world trade structure into consideration), unlike net export index. Fourth, it accounts for economic openness, using GDP as a scale variable. Fifth, it is hardly exposed to structural distortions. Finally, its sign is consistent with the sign of the net trade. We compare the new index with CEPII theoretically grounded econometric indicator and show that the proposed index has better empirical characteristics and is much easier to calculate and interpret.

T he article examines Russia's dependence on hightech imported goods. We improve the OECD hightechnology product classification by increasing the level of disaggregation, accounting for new goods, ensuring comparability over time, and differentiating goods by technological level on quite high levels of disaggregation. We describe the major trends in the world market for high-tech goods and identify the leading countries in each sector (most frequently, China, Germany, Republic of Korea, Switzerland, and Singapore) primarily by calculating net exports of high-tech goods in these sectors. We also assess Russian competitive positions in the global market for high-tech goods by sectors, applying the newly developed competitiveness index, and measure Russian dependence on high-tech goods imported from countries that recently imposed sanctions against Russia. We show that Russia's economy is highly dependent on imports of pharmaceutical goods and medical equipment, machinery and equipment (except nuclear reactors, fuel elements, engines and turbines), and electrical equipment. The sectors with most imports originating from 'sanctionimposing' countries are aircraft, medical and optical equipment, engines and turbines, and pharmaceutical goods. Computers and electronic equipment are at the opposite pole: in these sectors, China is the world leader and the key partner for Russia.
