The Role of the Clean Development Mechanism in Achieving China’s Goal of a Resource Efficient and Environmentally Friendly Society

This paper examines the impact of the clean development mechanism (CDM) on China’s progress in building a resource-efficient and environmentally friendly society, referred to as a dual-goal society. It presents China’s CDM activities from the perspective of policy directions, administrative arrangements and capacity building as well as outlines the regional trends and distribution of CDM projects across China’s 30 provinces. Based on regression analysis of 2006–2009 panel data, the research was able to provide estimates at provincial level of the impacts of CDM activities on China’s CO2 emission intensity, SO2 emission intensity and industrial dust emission intensity. The study concludes that the active CDM projects are mainly located in the less-developed central and west China where they have provided increased opportunities for sustainable development. Furthermore, the successful implementation of CDM projects across the country has significantly decreased the emission intensity of CO2, SO2 and industrial dust, which means that these activities have enhanced China’s ability to build the desired dual-goal society

Geographical interdependence, international trade and economic dynamics: the Chinese and German solar energy industries

The trajectories of the German and Chinese photovoltaic industries differ significantly yet are strongly interdependent. Germany has seen a rapid growth in market demand and a strong increase in production, especially in the less developed eastern half of the country. Chinese growth has been export driven. These contrasting trajectories reflect the roles of market creation, investment and credit and the drivers of innovation and competitiveness. Consequent differences in competiveness have generated major trade disputes

Are Chinese consumers at risk due to exposure to metals in crayfish? A bioaccessibility-adjusted probabilistic risk assessment

Freshwater crayfish, the world's third largest crustacean species, has been reported to accumulate high levels of metals, while the current knowledge of potential risk associated with crayfish consumption lags behind that of finfish. We provide the first estimate of human health risk associated with crayfish (Procambarus clarkii) consumption in China, the world's largest producer and consumer of crayfish. We performed Monte Carlo Simulation on a standard risk model parameterized with local data on metal concentrations, bioaccessibility (phi), crayfish consumption rate, and consumer body mass. Bioaccessibility of metals in crayfish was found to be variable (68-95%) and metal-specific, suggesting a potential influence of metal bioaccessibility on effective metal intake. However, sensitivity analysis suggested risk of metals via crayfish consumption was predominantly explained by consumption rate (explaining >92% of total risk estimate variability), rather than metals concentration, bioaccessibility, or body mass. Mean metal concentrations (As, Cd, Cu, Ni, Pb, Se and Zn) in surveyed crayfish samples from 12 provinces in China conformed to national safety standards. However, risk calculation of phi-modified hazard quotient (HQ) and hazard index (HI) suggested that crayfish metals may pose a health risk for very high rate consumers, with a HI of over 24 for the highest rate consumers. Additionally, the phi-modified increased lifetime risk (ILTR) for carcinogenic effects due to the presence of As was above the acceptable level (10(-5)) for both the median (ILTR = 2.5 x 10(-5)) and 90th percentile (ILTR = 1.8 x 10(-4)), highlighting the relatively high risk of As in crayfish. Our results suggest a need to consider crayfish when assessing human dietary exposure to metals and associated health risks, especially for high crayfish-consuming populations, such as in China, USA and Sweden.HZ by the National Natural Science Foundation of China (41273087).

A review of physical supply and EROI of fossil fuels in China

This paper reviews China’s future fossil fuel supply from the perspectives of physical output and net energy output. Comprehensive analyses of physical output of fossil fuels suggest that China’s total oil production will likely reach its peak, at about 230 Mt/year (or 9.6 EJ/year), in 2018; its total gas production will peak at around 350 Bcm/year (or 13.6 EJ/year) in 2040, while coal production will peak at about 4400 Mt/year (or 91.9 EJ/year) around 2020 or so. In terms of the forecast production of these fuels, there are significant differences among current studies. These differences can be mainly explained by different ultimately recoverable resources assumptions, the nature of the models used, and differences in the historical production data. Due to the future constraints on fossil fuels production, a large gap is projected to grow between domestic supply and demand, which will need to be met by increasing imports. Net energy analyses show that both coal and oil and gas production show a steady declining trend of EROI (energy return on investment) due to the depletion of shallow-buried coal resources and conventional oil and gas resources, which is generally consistent with the approaching peaks of physical production of fossil fuels. The peaks of fossil fuels production, coupled with the decline in EROI ratios, are likely to challenge the sustainable development of Chinese society unless new abundant energy resources with high EROI values can be found

Membership of Chinese Farmer Specialized Cooperatives and Direct Subsidies for Farmer Households: A Multi-Province Data Study

The introduction of direct subsidies to farming households and the development of farmer cooperatives has provided two important approaches to China’s twenty-first century food policy challenges. However, research undertaken largely separates and focuses on subsidies or cooperatives. This neglects their interaction and complementarities. This paper seeks to rectify this omission using a survey from 35 farmer specialized cooperatives (FSCs) and 561 farming households in 16 provinces, based on a two-stage treatment effect model. The findings suggest FSCs have become important organizations that improve farmers’ net income. Moreover, usage of agricultural machinery and direct subsidies also result in higher net income, though they have little impact on farmers’ machinery investment. The results provide an evidence source that contributes to debate concerning government subsidy policy. Policy may act more like an income transfer program, since it has little impact on farmers’ investment in agriculture. The study also highlights that there are complementary effects between FSCs and direct subsidies, and that China’s cooperative policy integrated with direct subsidies could be progressive

Time allocation and firm performance: The case of Chinese entrepreneurs

This paper analyses the effect of time allocation on the financial performance of entrepreneurial firms. We apply the Lewbel (2012) estimator to a pooled dataset of Chinese private manufacturing firms that are managed by their owners. Time is allocated between management, networking and study activities. After accounting for endogeneity, we find an inverted U-shaped relationship between management hours and firm performance and between networking and firm performance. However, no relationship between time spent studying and firm performance is observed. We also find that the managing hours-performance relationship is particularly strong for companies managed by entrepreneurs who own more than 75% of share, for companies that are managed by owners with previous experience, for male entrepreneurs and for smaller sized firms

What can Africa Learn from China's Experience in Agricultural Development?

Submitted version of Bulletin articleThere has been a growing interest in China’s rapid economic growth, particularly agriculture-led growth and poverty reduction. In fact, China and Africa have developed their agriculture under different historical conditions. China’s agriculture-led growth and poverty reduction and small holder based agricultural development policy can provide a useful model for African countries to develop their own agricultural development strategies to reduce poverty.DFID, ESR
