摘要
利用矩阵分解技术,证明了农业经济产出过程农业内部乘数效应、外部乘数效应和城市涓滴效应共同决定。在对北京1985—2007年的投入产出分析的基础上,对城乡经济关系得出新的理解:在城镇化和市场化初期,农业经济的大部分收益来自于城镇的涓滴作用;随着城镇飞速发展,城乡二元结构对比强烈,农业的绝大部分收益来自农业内部;最后,在食品安全、生态保育和一系列社会问题以及经营者在农村寻求经济机会的推动下,农业和城市经济开始结合,城市反哺农业。研究表明,在各个时期,农业经济的发展在很大程度上依赖于城市经济,在市场化初期这种程度在60%—70%左右,而在今后的城乡一体化发展阶段,农业的绝大部分收益会来自于城市经济的涓滴作用,农业的食品、生态和社会功能应摆在优先重要位置。
The purpose of the paper is to explore the wealth generating processing of rural economy and mutual dependent relationship between urban and rural economies using Input-Output（I-O） techniques.With matrix decomposition technique,it identifies the wealth of rural economy is generated by internal and external multipliers of rural economy,and the leaking effect from urban economy to rural economy.Based on the case study of Beijing from 1985-2007,this I-O analysis generates a new perspective of urban-rural economic relationship.On the initial stage of urbanization and privatization,rural economic development is predominately benefited from the urban leaking effect.This situation is reversed with dualistic urban and rural realms,and rural economy is self-generated when labor is attracted and land is claimed by the urban development.Such dualistic structure yet creates a lot of social and environmental problems.Urban economy has to contribute to rural economy,particularly at the stage of advanced economic development or post-urbanization.The study verifies rural economic development is much dependent on the urban economy;such dependence is about 60-70% and much larger in the consequent integrated urban-rural development.Facing the fact that rural economic development is largely contributed by the urban,it need prioritize its food security,ecological and social function.
