川中丘陵区农业结构效益与竞争力研究

Structural Benefits and Competitiveness of Agriculture in the Hilly Areas in Central Sichuan

运用偏离—份额分析法,将农业经济增长分解成三个方面,即区域份额增长、结构偏离分量和竞争力偏离分量。以川中丘陵区及所包含的广安市等6个地区为研究对象,选取这些地区的农林牧渔总产值及农业部门产值为样本数据,考察了川中丘陵区2003—2010年间农业经济增长差异,分析了农业部门的结构效益和竞争力,发现川中丘陵区农业经济发展较快,农业结构较合理,但缺乏竞争力;同时比较区内6个地区农业经济发展过程,发现遂宁市发展最慢,农业结构效益较高,缺乏区域竞争力;内江市发展速度最快,区域竞争力较强,但农业结构效益略低;并针对分析结果提出了川中丘陵区调整农业结构、增强农业竞争力的建议。

Based on shift- share method, we resolve agricultural economic growth into three aspects： area share growth,structure deviation component and competitive deviation component. Targeting on Guang＇an City and other five cities in the hilly areas in central Sichuan province ,we selected the total output of agriculture,forestry and fishery as well as the output of agriculture sector in these areas as sample data, and investigated the differences in agricultural economic growth in the hilly areas of central Sichuan from 2003 to 2010. After analyzing the structural benefit and competitiveness of the agriculture sector, we concluded that agricultural economy in these areas has developed fast with reasonable agricultural structure but relatively weak competiveness. When comparing the agricultural economic development of the 6 areas within this region, we found that agricultural economic development of Suining is the slowest,and it has structural benefit but lacks competiveness while Neijiang, the one developing fastest, is of strong competitiveness ,but its structural benefit is lower. Finally, the authors put forward some suggestions on adjusting agricultural structure and enhancing agricultural competitiveness in the hilly areas of central Sichuan province according to the results of the analysis.
