Abstract
As one of the main grain-producing areas in China, urban agglomeration in the middle reaches of the Yangtze River plays an important role in the development of agricultural production for China’s grain supply. The existing studies about agricultural production efficiency lack of regional coordination analysis at both macro and micro levels, and only few studies consider the impact of agricultural production environment pollution and other undesirable outputs. Based on the input–output index system of agricultural green production, Slacks-based model (SBM) was adopted to measure the agricultural green production efficiency of 31 prefecture level cities in the middle reaches of the Yangtze River from 2008 to 2018, and the Tobit model of panel fixed effect was used to analyze the driving effect of external factors that affect the agricultural green production efficiency of urban agglomeration in the middle reaches of the Yangtze River. At the same time, the research methods at both macro and micro levels provide ideas for the research of transregional production efficiency. The results showed that: (1) the agricultural green production efficiency of urban agglomeration in the middle reaches of the Yangtze river is relatively low, with 2009 and 2013 as the inflection points, showing a stable trend of rise and decline; (2) The green agricultural production efficiency of urban agglomeration in the middle reaches of the Yangtze River presents the spatial distribution characteristics of “high in the west and low in the east”. The regional efficiency difference is obvious, the gap gradually expands, develops from the equilibrium to the polarization; (3) Urbanization development and government intervention has a significant restraining effect on the improvement of agricultural green production efficiency, and opening to the outside world produces a remarkable influence on the improvement of agricultural green production efficiency, however, economic development and industrial structure have little impact on the improvement of agricultural green production efficiency. Therefore, it is necessary to increase investment in technological innovation, promote agricultural transformation and upgrading, promote rational factors allocation and promote coordinated development of agriculture based on regional production differences.
Highlights
The massive loss of agricultural production factors has threatened the stability of the production of the regional agriculture, which is detrimental to the food security of China [4]
By studying the agricultural green production efficiency and its driving factors, this paper aimed to promote the improvement of regional agricultural production efficiency, improve the quality and efficiency of agricultural economic growth in urban agglomerates in the middle reaches of the Yangtze River, to realize the green development of agriculture in urban agglomerates in the middle reaches of the Yangtze
This paper aims to fill those gaps from the following aspects: (1) this paper focuses on using the relevant knowledge of the undesired output Slacks-based model (SBM) model and Tobit model to measure, using the relevant knowledge of agricultural carbon emissions to build an agricultural green production efficiency evaluation system
Summary
Compared with the rapid economic growth in recent years, the agricultural development in this region is rather weak, there exists massive loss of rural labor force and the encroachment of urban development and construction on agricultural land [3]. Taking the secondary urban agglomeration in the middle reaches of the Yangtze River, that is, the urban agglomeration around Changsha-Zhutan, as an example, the rural labor force decreased by about 188,000 and the total cultivated land resources decreased by about. By studying the agricultural green production efficiency and its driving factors, this paper aimed to promote the improvement of regional agricultural production efficiency, improve the quality and efficiency of agricultural economic growth in urban agglomerates in the middle reaches of the Yangtze River, to realize the green development of agriculture in urban agglomerates in the middle reaches of the Yangtze
