The impact of agricultural comprehensive development on agro-ecological efficiency of China - evidence from perspective of scale and structure

Abstract

Promoting the agricultural sustainable development is one of the core objectives of agricultural comprehensive development (ACD), and the core of agricultural sustainable development lies in enhancing agro-ecological efficiency (AEE). Based on inter-provincial panel data from 2003-2017, the AEE was measured by a unexpected super-efficient SBM model. From the perspective of investment scale and investment structure, the impact of investment scale in ACD on AEE was examined using a panel econometric model, then characterizing the investment structure by the proportion of government funds in the investment of ACD, examining the non-linear relationship between investment structure of ACD and AEE seeking a reasonable proportion of government expenditure. Finally, a spatial econometric model was constructed to test the spatial spillover effect of the scale and structure of investment in ACD on AEE. Results showed that: (i) AEE of China is on the rise overall, but the efficiency level is still low and there is large scope for improvement. (ii) Due to the inefficient use of funds and the lag in the transformation of agricultural benefits, the scale of investment in ACD has a significant negative impact on AEE in the current period. (iii) The impact of investment structure of ACD on AEE presents a significant “inverted N” relationship, and the optimal proportion of government fund investment structure is 76.71%. The reasonable structure of investment in ACD at different food functional areas shows differences. (iv) After considering the spatial effect, the impact of ACD remains robust, but the spatial spillover effect prolongs the time lag of this impact of investment scale and starts to have a positive impact in the 2nd year after the investment. Guarantee the investment scale in ACD, reduce financial redundancy, establish a cooperation mechanism between ACD and agricultural ecological protection in neighboring areas, and increase the introduction of private capital can achieve sustainable development of agricultural economy.

From Large to Powerful: International Comparison, Challenges and Strategic Choices for China’s Livestock Industry

“…The main factors affecting the improvement in China's livestock industry competitiveness include market price, production cost, technology level, resource conditions, processing capacity, quality and safety, trade barriers, and policy support, and studies have suggested that multiple measures be taken to sustain efforts to fast-track the improvement in the international competitiveness of the livestock industry [39][40][41][42]. Other studies have considered the characteristics of the high-quality development of the industry [43][44][45] and systematically explored the challenges and practical paths for accelerating development [46][47][48].…”
