The purpose of this paper is to develop a comprehensive overview of green innovation (GI) in China, which is carried out by reviewing the evolution of GI from 2000 to 2019, and the main type of technology, actors and localizations. When appropriate, GI is compared to non-GI.

The study uses patent data from the European Patent Office database (PATSTAT); these data are processed to map trends and identify the main contributors to GI and the location of such innovation. The findings are then discussed and complemented with academic literature.

Key findings reveal an increasing divergence between GI and nongreen innovation after the 2008 crisis. It is also observed that solar energy appears to be the main component of GI in China, with a shift from photovoltaic thermal energy to solar photovoltaic energy after 2008. Other areas, such as waste management, greenhouse gases capture and climate change adaptation, are less innovative. Companies play an essential role in the development of all types of innovation. In terms of location, green patents are mainly filed in China’s three main megacities. The study also highlights the significant role of the Chinese state, which led policies shaping the trajectories and forms of GI.

This study expands knowledge on GI in China, highlighting its main specificities and the role of key actors. It provides to the reader a comprehensive picture of China’s green policies and innovation realities. The results can therefore be used to improve the understanding of GI evolution in China and facilitate the formulation of new research questions.

By age 77 a plurality of women in wealthy Western societies are widows. Comparing older (aged 70+) married women to widows in the American Time Use Survey (ATUS) 2003–2018 and linking the data to the Current Population Survey allow inferring the short- and longer-term effects of a demographic shock – husband's death – and measuring the paths of adjustment of time use to it. Widows differ from otherwise similar married women, especially from married women with working husbands, by cutting back on home production, mainly food preparation and housework, mostly by engaging in less of it each day, not doing it less frequently. The ratio of time to money expenditures on one item – food – is higher among married older couples than among widows. Widows are alone for 2/3 of the time they had spent with their spouses, with a small increase in time with friends and relatives shortly after becoming widowed. Older French, Italian, German, and Dutch women exhibit similar differences in time use; European widows also feel less time stress than married women. Following older women in 18 European countries before and after a partner's death shows that becoming widowed reduces their feelings of time pressure.
