In this work we slwly linear polynomial operators preserving some consecutive i-convexities and leaving in-verant the polynomtals up to a certain degree. First we study the existence of an incompatibility between the conservation of cenain i-cotivexities and the invariance of a space of polynomials. Interpolation properties are obtained and a theorem by Berens and DcVore about the Bernstein's operator ts extended. Finally, from these results a genera'ized Bernstein's operator is obtained.

作者： Miquel munoz Cabre Kevin P. Gallagher Zhongshu Li Global Development Policy (GDP) Center Boston University USA Boston University USA Woodrow Wilson School Princeton University USA

This paper compares the global flows of Chinese overseas investment in power plants with renewable energy investment potential embodied in ＂Nationally Determined Contributions.＂ With over US$1tn （671 GW） in Nationally Determined Contributions renewable energy investment potential in developing countries, we estimate the total level of power plant investments from China＇s policy banks and commercial entities since the early 2000s at US$216bn （158 GW）. Although past investment has mainly been directed at fossil fuels and hydroelectric power, we argue that China is uniquely poised to lead renewable energy global investments for three reasons：（i） China＇s solar and wind industries are globally competitive; （ii） Chinese policy banks can give domestic firms advantages in financing global expansion; and （iii） renewable energy investment opportunities still exist in developing countries with less sovereign risk than for traditional energy investments. The Chinese government should provide special incentives for the policy banks to capitalize on these investment opportunities by deploying Chinese solar and wind technologies to Belt and Road countries and beyond.
