农业高质量发展:水平测算、时空分异与收敛特征

AGRICULTURAL HIGH-QUALITY DEVELOPMENT:LEVEL MEASUREMENT,SPATIAL-TEMPORAL DIFFERENTIATION AND CONVERGENCE CHARACTERISTICS

[目的]以新发展理念为引领,探究区域层面农业高质量发展水平、时空分异与收敛特征,试图清晰展现我国农业高质量发展的“非均衡”全况。[方法]文章利用2011—2020年省域面板数据,通过构建农业高质量发展综合评价指标体系,并运用熵值法、Dagum基尼系数法、变异系数法与空间收敛模型等方法,验证了我国农业高质量发展的时空差异。[结果]我国农业高质量发展水平呈现不断上升的趋势,总体差异呈波动下降趋势,但区域差异较明显,地区间差异是总体差异的主要来源;除东北地区外,我国农业高质量发展均存在σ收敛、空间绝对β收敛、空间条件β收敛,分区域与分时期的收敛性具有明显的时空差异特征。[结论]进一步提高农业高质量发展水平、缩小区域差异,要提高农业科技创新能力,加强农业基础设施建设,深入贯彻新发展理念,转变农业发展方式。遵循比较优势发展原则,建立跨区域的农业协同创新平台,加强区域农业高质量融合协同发展。

Guided by the new development concept,the spatio-temporal differentiation and convergence characteristics of high-quality agricultural development at the regional level is explored to clearly demonstrate the unbalanced overall situation of the high quality agricultural development in China.Based on the provincial panel data from 2011 to 2020,a comprehensive evaluation index system of agricultural high-quality development was constructed,and the entropy method,Dagum Gini coefficient method,coefficient of variation method and spatial convergence model were used to verify the spatio-temporal differences of agricultural high-quality development in China.The results were showed as follows.The level of high-quality agricultural development in China showed a rising trend and the overall difference was fluctuating and declining,but the regional difference was obvious,and the regional difference was the main source of the overall difference.Moreover,except for Northeast region,there were o convergence,spatial absoluteβconvergence and spatial conditionalβconvergence in the high-quality agricultural development in China,and the convergence between regions and periods had obvious spatial and temporal differences.Therefore,in order to further raise the level of high-quality agricultural development and narrow regional differences,we need to improve our capacity for innovation in agricultural science and technology,strengthen agricultural infrastructure development,thoroughly implement the new development philosophy,and transform the pattern of agricultural development.What's more,we should follow the principle of comparative advantage development,establish a cross-regional agricultural collaborative innovation platform,and strengthen the high-quality integrated and coordinated development of regional agriculture.
