China is a considerable grain importer in the world. However, the sustainability of China’s grain imports has been greatly challenged by its increasing economic policy uncertainty (EPU).This paper constructs the indicators of economic and environmental sustainability of China’s net grain imports and analyzes the impact of its EPU index on these indicators with a Time-Varying Parameter Stochastic Volatility Vector Autoregression (TVP-SV-VAR) model to explore how China’s EPU affects the sustainability of its net grain imports. The main conclusions are as follows.(1) The sustainability of China’s net grain imports fluctuated from 2001 to 2019. (2) China’s EPU has a negative impact on the economic sustainability of its net grain imports. A higher EPU index leads to a lower net import potential ratio and higher trade cost. (3) China’s EPU has a significant negative impact on the environmental sustainability of its net grain imports. It has the greatest negative impact on virtual water imports and smaller impact on virtual land imports and embodied carbon emission. Therefore, China’s EPU affects the sustainability of its net grain imports negatively through its impact on its net grain import potential ratio, trade cost, and virtual land, virtual water, and embodied carbon emissions in net grain imports.

Poverty alleviation has attracted extensive attention worldwide. This paper investigated the spatial agglomeration effect and dynamics driving rural education levels (namely, primary education, junior secondary education, and senior secondary education) and rural poverty in 27 provinces of China in 2010-2017. The results of a spatial autoregressive (SAR) model revealed that different education levels have distinct effects on rural poverty, and the impact of compulsory education on rural poverty is greater than that of senior secondary education. We further found that rural poverty in a region is clearly not only internally driven but also impacted by the poverty rate in the surrounding provinces, suggesting that regional poverty alleviation policies should combine regional education differences and learn from poverty alleviation through education experience in surrounding areas. Thus, the findings established in this paper have significant implications for targeted poverty alleviation measures in China by improving education.

The minimum purchase price policy for wheat and rice implemented by the Chinese government has achieved the fundamental goals of stabilizing grain prices, promoting production, and ensuring food security. This policy has also had negative impacts such as domestic and foreign price spreads and continuous increases in stocks and imports, which are not conducive to China’s grain security development and thus unsustainable. Therefore, this paper builds a partial equilibrium model of China’s grain market by simulating the effects of canceling or reducing the minimum purchase price on the market price, production, consumption, stock, and net import of wheat and then evaluates the sustainability of various adjustment programs. The research results show that first, lowering the minimum purchase price of wheat can reduce the domestic and foreign price spread, stock, and imports to a certain extent; however, it cannot fundamentally solve the negative impact of this policy. Second, cancellation of the minimum wheat purchase price policy can significantly reduce domestic and foreign price spread, stock, and imports; however, it will also significantly reduce wheat production and threaten China’s grain security. Third, cancellation of the minimum wheat purchase price and the increase in agricultural production subsidies can solve the negative impact of the minimum purchase price policy and reduce the impact of the cancellation of the minimum purchase price policy on grain supply security. This policy adjustment is more sustainable than China’s current policy. Finally, this paper asserts that China’s grain price policy reform will influence and have implications for stakeholders in the global grain industry.
