In this study, we first investigate agricultural development in China over the past four decades and then analyze the opportunities and challenges that China’s agricultural development is facing. Lastly, we forecast future agricultural development in China. Our study shows that China’s agriculture has experienced rapid growth over the past four decades; institutional innovation, technological progress, marketization reform, and public investment are the four major driving forces. However, agricultural development in China still encounters many challenges, including a slowdown in productivity growth, degradation of soil and water, and uncertainty of the global supply chain. This implies that, towards 2050, China should adhere to the principles of innovation, green, high efficiency, and sustainability, and accelerate agricultural modernization by efficiently producing more high-valued and green products to maintain food security and self-sustained grain supply. To achieve this long-term goal, the government should deploy seven major strategies focusing on biological technology, seedling innovation and among others, and initiate a series of agriculture-supportive policies.","PeriodicalId":65586,"journal":{"name":"中国工程科学","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67367589","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

China’s agricultural labor productivity is less than 1/3 of that in the manufacturing and service industries. Our analysis on the trend of agricultural development suggests that it is essential to raise the agricultural labor productivity through internal labor division to ensure national food security. The breeding industry needs to transform toward scaled and modernized development and the planting industry needs to change to a new pattern — 20% of large-scale farmers produce 80% of agricultural products or contribute 20% of added value while 80% of small-scale farmers produce 20% of agricultural products or contribute 80% of added value. Large-scale farmers mainly produce bulk agricultural products including grain to ensure food security while small-scale farmers develop high-value agriculture to ensure income growth. Eventually, the labor productivity of large- and small-scale farmers will converge to achieve common prosperity, which is inevitable for China’s agricultural development and is an ideal vision in line with national realities. However, the task of transforming to the new pattern is arduous, and the government needs to make major strategic deployments development, improve the land transfer markets, optimize the innovative system of agricultural science and technology as well as the human capacity building system, and establish an organizational guarantee system to realize agricultural modernization.","PeriodicalId":65586,"journal":{"name":"中国工程科学","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67368111","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Promoting the construction of urban agglomerations in the Yangtze River Basin is crucial for accelerating the development of the Yangtze River Economic Belt. The five urban agglomerations in the Yangtze River Economic Belt were used as the research objects; their environmental carrying capacities and the coupling relationship between these capacities and urban agglomeration development were explored. Based on the results, we categorized these urban agglomerations into three types: (1) mature–environmental overload type constituting the urban agglomeration in the Yangtze River Delta, (2) high-speed development–environmental overload type, comprising the urban agglomerations in Chengdu–Chongqing and the middle reaches of the Yangtze River, and (3) cultivation–environmental non-overload type that comprised the urban agglomerations in central Guizhou and central Yunnan. Herein, we propose strategic suggestions for the development of urban agglomerations in the Yangtze River Economic Belt considering the aspects of ecological space control, optimization of spatial land patterns, green development of urban agglomerations, and improvement of the human settlement environment. These aim to strengthen the guiding role of environmental carrying capacity in developing urban agglomerations and provide basic support for promoting high-quality development of the Yangtze River Economic Belt.","PeriodicalId":65586,"journal":{"name":"中国工程科学","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67368423","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The energization of transportation infrastructure assets and the clean transformation of transportation energies are effective decarbonization strategies for solving severe challenges such as resource shortage, climate change, and environmental pollution. This study first reviews the integration history of road transportation and energy and investigates the demand for and trends in national energy security, clean transformation of the energy supply, energization potential of transportation infrastructure assets, and intelligization of transportation. A pathway for integrating road transportation with the energy sector in China is proposed based on an assessment of the available wind and solar resources and the self-consistent supply capacity of energies within road transportation. Moreover, a roadmap for integrating road transportation with renewable energies is proposed by considering the carbon peak and neutralization targets. Finally, we propose two strategies to achieve these goals. First, China should enhance technology research, innovation, development, and integration, as well as improve the industry chain. Additionally, the government should provide policies for improving top-level design and strategic planning to exploit new market modes and strengthen international cooperation.","PeriodicalId":65586,"journal":{"name":"中国工程科学","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67370330","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
