Nature-based solutions to China’s development challenges
Overview
While China’s remarkable industrial development has lifted hundreds of millions out of poverty and created a large middle class, it has also caused significant biodiversity loss, ecosystem degradation, and pollution in urban and rural areas. These environmental crises threaten human health and safety and undermine long-term economic development.
In response, China’s government is now promoting a system of ecological civilization to align environmental conservation and socio-economic development through initiatives in natural capital investment, sustainable infrastructure, biodiversity protection and renewable energy. Notably, China has committed to establishing official protection over 30% of its land by 2030 and achieving carbon neutrality by 2060.
SCCEI is collaborating with the Stanford Natural Capital Project (NatCap) and the Chinese Academy of Sciences’ Research Center for Eco-Environmental Sciences (RCEES) to advance nature-based policy solutions and support sustainable development in China and around the world. Our research focuses on four key areas: Ecological Civilization, Gross Ecosystem Product, Urban Nature and Health, and Nature and Rural Vitalization.

Ecological Civilization
Ecological Civilization, a new policy system in China, is designed to align environmental conservation with socio-economic development. Our research analyzes this emerging policy framework and identifies opportunities for collaboration with government, enterprises, and civil society.
Gross Ecosystem Product
Gross Ecosystem Product (GEP) is an index that aggregates the total value of ecosystem goods and services into a single monetary metric. Co-developed by NatCap and RCEES, GEP is now being piloted in China on local and national levels.
Urban Nature and Health
With over 1 billion people projected to live in China’s cities by 2030, the mental and physical health of the urban population has become a top priority. Our research identifies how nature solutions can improve public health outcomes, with a focus on the role of urban greenspace.
Nature and Rural Vitalization
China’s rural countryside faces increasing needs for both environmental and economic investment. Our research aims to coordinate investments in natural capital with investments in human capital to transform China’s countryside into a frontier of sustainable development.
Stanford scholars are setting and expanding research agendas to analyze China’s economic development and its impact on the world. The newly launched Stanford Center on China’s Economy and Institutions — co-directed by SIEPR senior fellows Hongbin Li and Scott Rozelle — is supporting their work. In this SIEPR Policy Brief, Li and Rozelle outline the research underway by the new center's affiliates.

The home language environment is critical to early language development and subsequent skills. However, few studies have quantitatively measured the home language environment in low-income, developing settings. This study explores variations in the home language environment and child language skills among households in poor rural villages in northwestern China. Audio recordings were collected for 38 children aged 20–28 months and analyzed using Language Environment Analysis (LENA) software; language skills were measured using the MacArthur–Bates Mandarin Communicative Developmental Inventories expressive vocabulary scale. The results revealed large variability in both child language skills and home language environment measures (adult words, conversational turns, and child vocalizations) with 5- to 6-fold differences between the highest and lowest scores. Despite variation, however, the average number of adult words and conversational turns were lower than found among urban Chinese children. Correlation analyses did not identify significant correlations between demographic characteristics and the home language environment. However, the results do indicate significant correlations between the home language environment and child language skills, with conversational turns showing the strongest correlation. The results point to a need for further research on language engagement and ways to increase parent–child interactions to improve early language development among young children in rural China.
Universities contribute to economic growth and national competitiveness by equipping students with higher-order thinking and academic skills. Despite large investments in university science, technology, engineering and mathematics (STEM) education, little is known about how the skills of STEM undergraduates compare across countries and by institutional selectivity. Here, we provide direct evidence on these issues by collecting and analysing longitudinal data on tens of thousands of computer science and electrical engineering students in China, India, Russia and the United States. We find stark differences in skill levels and gains among countries and by institutional selectivity. Compared with the United States, students in China, India and Russia do not gain critical thinking skills over four years. Furthermore, while students in India and Russia gain academic skills during the first two years, students in China do not. These gaps in skill levels and gains provide insights into the global competitiveness of STEM university students across nations and institutional types.
Background: The educational resources that parents provide at home are crucial to their children’s development. In this study, we focused on home reading environment, a key contributor to success rates regarding the mastery of reading skills. We aimed to investigate students’ home reading environments and examine its effect on the reading development of primary school students in rural China. Methods: We draw on a dataset composed of 10,740 randomly selected primary school students and their households in rural areas of Jiangxi province in China. Surveys were administered by trained enumerators in May 2015. Results: The results show that students exhibited quite poor reading environments and reading outcomes. Specifically, we found the majority of the rural students lacked reading and learning resources in the context of their families and their parents did not enjoy reading or support their children’s reading. Moreover, our regression analysis documented students with poorer home reading environments are more likely to have worse reading performance. Conclusion: Our study supports the significance of the home reading environment in the reading development of students in the upper elementary grades in rural China. Furthermore, the results suggest that the home reading environments of rural Chinese students must be improved.

This paper examines the external validity of health intervention by comparing the impacts of providing free eyeglasses on the educational performance of nearsighted children in two settings: rural public schools in Western China and urban private migrant schools in Eastern China. The intervention significantly improves educational outcomes by 0.14 standard deviations in math in rural public schools but not in private migrant schools. The difference in measured impacts is due in part to lower quality schooling in migrant schools in Eastern China. Our findings show that only when school is providing a quality education, health interventions might increase student learnings.

Purpose:
Internet use has become particularly prevalent among adolescents, prompting much thought and concern about both its potential benefits and adverse effects on adolescent learning outcomes. Much of the empirical literature on the impact of Internet use on adolescent learning outcomes is mixed, and few studies examine the causal relationship between the two in rural China. In order to bridge these gaps, we use empirical analysis to investigate the effect of Internet use on the learning outcomes of adolescents in rural China.
Design/methodology/approach:
We use fixed effect models with samples drawn from a large nationally representative dataset (the China Family Panel Studies—CFPS) to identify the causal impacts of Internet use on the learning outcomes of three cohorts (Cohort A (N = 540), Cohort B (N = 287) and Cohort C (N = 827)) of adolescents in rural China.
Findings:
The results of the descriptive analysis show a continued increase in the number of adolescents accessing the Internet and the amount of time they spend online. The results of the fixed effect models show that Internet use has positive (in many of the analyses), but mostly insignificant impacts, on the learning outcomes of adolescents. In the sets of results that find significant associations between Internet use and learning outcomes, the measured effects are moderate.
Originality/value:
This study investigates the causal relationship between Internet use and adolescent learning outcomes in rural China. The findings claim that there is not a great need to worry about adverse effects of Internet use on adolescent learning development. Attention, however, should focus on seeking ways to improve the positive effects of the Internet use on adolescent learning outcomes. The study will provide a reference and experience for the development of education and the Internet in rural areas and promote the integrated development of urban and rural areas in China.
Climate change and human activities exert a wide range of stressors on urban coastal areas. Synthetical assessment of coastal vulnerability is crucial for effective interventions and long-term planning. However, there have been few studies based on integrative analyses of ecological and physical characteristics and socioeconomic conditions in urban coastal areas. This study developed a holistic framework for assessing coastal vulnerability from three dimensions - biophysical exposure, sensitivity and adaptive capacity - and applied it to the coast of Bohai Economic Rim, an extensive and important development zone in China. A composite vulnerability index (CVI) was developed for every 1 km2 segment of the total 5627 km coastline and the areas that most prone to coastal hazards were identified by mapping the distribution patterns of the CVIs in the present and under future climate change scenarios. The CVIs show a spatial heterogeneity, with higher values concentrated along the southwestern and northeastern coasts and lower values concentrated along the southern coasts. Currently, 20% of the coastlines with approximately 350,000 people are highly vulnerable to coastal hazards. With sea-level rises under the future scenarios of the year 2100, more coastlines will be highly vulnerable, and the amount of highly-threatened population was estimated to increase by 13–24%. Among the coastal cities, Dongying was categorized as having the highest vulnerability, mainly due to poor transportation and medical services and low GDP per capita, which contribute to low adaptive capacity. Our results can benefit decision-makers by highlighting prioritized areas and identifying the most important determinants of priority, facilitating location-specific interventions for climate-change adaptation and sustainable coastal management.

A burgeoning literature has documented the importance of elite colleges. Yet, little is known about access to elite education and its labor market implications in China, a country that produces one in every five college graduates in the world. College admission in China is governed by a single exam—the national college entrance exam, and the government sets admission cutoff scores for elite colleges. We examine the impacts of scoring above the elite-tier cutoff on a student's access to elite colleges and wage outcomes after graduation, using the discontinuity around the cutoff score. By employing hand-collected survey data, we find that scoring above the cutoff not only increases the chance of entering an elite college but also raises a young person's first-job wages after graduation. We also find that those just above the cutoff have peers with higher scores and better social networks than those below the cutoff, but it is less clear whether the two groups use their time differently in college.
Background: Maternal health during pregnancy is a key input in fetal health and child development. This study
aims to systematically describe the health behaviors of pregnant women in rural China and identify which
subgroups of women are more likely to engage in unhealthy behaviors during pregnancy.
Gross Ecosystem Product (GEP) is an aggregate measure of the monetary value of final ecosystem services, or the direct benefits that people derive from nature. In this study, we focus on the 'Chang-Zhu-Tan' (CZT) urban agglomeration—an emerging megacity of over 15 million people situated on the Yangtze River—as a case study of the dynamics of ecological production amidst rapid urbanization. In this study, we couple a spatial-temporal analysis of regional ecological change based on remote-sensing data with economic valuation methods (e.g. travel cost method) using official statistics and survey data. We find that while the land cover of natural ecosystems decreased slightly between 2000 and 2015, their quality—and therefore economic value—greatly improved. From 2000 to 2015, the GEP of CZT increased by 56.77%. In particular, the value of regulating services grew by 7.43% (calculated using inflation-adjusted prices). GEP can reflect nature's contribution to human well-being. At the same time, its long-term trends can serve as an indicator of the extent and quality of local and regional ecosystems, thereby providing a corrective or complement to more conventional measures of development. Although urbanization increases spatial constraints on the management of natural capital, progress in ecological protection and restoration can still improve the quality of ecosystems and the services they provide. Our study shows how GEP, and the value of natural capital it reflects, can grow amidst the pressures of rapid urbanization.

This paper studies how the COVID-19 pandemic has affected labor demand using over 100 million posted jobs on one of the largest online platforms in China. Our data reveals that, due to the effects of the pandemic both in China and abroad, the number of newly posted jobs within the first 13 weeks after the Wuhan lockdown on January 23, 2020 was about one third lower than that of the same lunar calendar weeks in 2018 and 2019. Using econometric methods, we show that, via the global supply chain, COVID-19 cases abroad and in particular pandemic-control policies by foreign governments reduced new job creations in China by 11.7%. We also find that Chinese firms most exposed to international trade outperformed other firms at the beginning of the pandemic but underperformed during recovery as the Novel Coronavirus spread throughout the world.

Purpose: This study aims to bridge the gaps in the existing literature by studying the links between children's development and the subjective well-being of the caregivers using first-hand data collected in rural China. Design/methodology/approach: Although the broad array of literature has examined the effects of child development on the subjective well-being of caregivers, the relationship between early childhood development and caregiver subjective well-being has not been well-studied using sample families with potential developmental delay in rural China. Also, existing research has relied on maternal reports to evaluate the developmental status of children. The study used data collected from 32 townships in seven nationally designated poverty counties in the Qinling mountainous area in 2016. The authors measure child development using the social-emotional module of the Ages & Stages Questionnaire and Bayley Scales of Infant and Toddler Development–Third Edition. Findings: The authors find that child development indicators are correlated with caregiver subjective well-being. In particular, social-emotional skills are positively associated with life evaluations and positive emotion. However, we do not find any significant correlation between child development and negative emotion or depression, anxiety and stress scores. Originality/value: The value of this study is to report the indicators of child development in rural China and examines the correlation between child development and caregivers' subjective well-being.
