摘要
运用产业结构转换系数、农业多样化指数、多部门经济分析模型、能源生产弹性系数等方法,对1978~2011年榆林市农村转型发展进行深入研究。研究发现：① 1978~1991年,榆林市三次产业结构转换速度系数为0.123,产业结构缓慢转换;1992~1997年,伴随着中国经济改革,产业结构逐步优化;1998~2003年榆林市产业转换速度达最大值0.276;2004年后,以能源经济为主导的第二产业区域经济发展,产业转换速度有所回落。1991~2011年,榆林市产业结构变动对经济增长的贡献值平均为3.94%,GDP增长的29%是由产业结构变动造成;②1991~2011年榆林市能源生产弹性系数维持在1.8左右,能源资源开发44.44%的价值外溢。产业结构偏离度、比较劳动生产率、二元对比系数均说明了榆林市农业生产效益较低,以能源化工为主的重工业对劳动力的吸纳能力有限。③1990~2011年,榆林市农村居民恩格尔系数由63.07%下降到36.70%,传统食物消费模式逐渐转变,农民生活水平提升。加快能源资源区农村转型发展,促进能源资源开发与农村经济互促发展成为榆林市当前面临的重要任务。
Using the methods of industrial structure entropy, conversion coefficient of industrial structures, agri- cultural diversification index, multi-sectoral model of economic analysis, energy production coefficient, the ar- ticle makes intensive study on rural transformation development of Yulin City in Northern Shaanxi. From 1978 to 2011, rural development in Yulin had gone through 5 stages, which were reform and opening up, exploita- tion of Shenfu coalfield, promotion of market economy, the construction of energy and heavy chemical indus- try base and new countryside construction. The maximum conversion velocity coefficient of industrial struc- tures in Yulin was 0.276 in 1998 to 2003, After 2004, the conversion velocity coefficient of primary and sec- ondary industries decreased sharply while that of the second industry increased, which showed that industrial structure of Yulin was in the process of industrialization from the lower level to the higher one. In 2011, the proportion of household operating income to farmer net income decreased to 52.8%, which was the main source of rural income, meanwhile, the proportion of food consumption expenditttre decreased from 63.07% in 1990 to 19.9% in 2011, which was the major expenditure of rural region. From 1991 to 2011, the average con- tribution degree to the economic growth of industrial structure change was 3.94%; meanwhile, the 29% of GDP growth is produced by industrial structure change. The elastic coefficient of energy production in Yulin was 1.8, the 44.44% of developed energy resources value was spilled over. All the above showed that agricul- tural production efficiency of Yulin is relatively low, the heavy industry＇ s capability to absorb agricultural la- bor force is limited, so the deviation of industrial structure and the employment structure is significant.
