撂荒农地再利用的生态经济效益及其影响因素——基于粤赣100家农业经营主体的调查

研究目的:通过对粤赣100家农业经营主体调查,研究撂荒农地再利用的生态经济效益及其影响因素,并提出相应的建议。研究方法:首先应用DEA模型中的CCR方法测度了撂荒农地再利用的生态经济效益,并进一步应用半对数回归模型和主成分分析法,实证分析了撂荒农地再利用的生态经济效益的影响因素。研究结果:总体上,撂荒农地再利用的生态经济效益最高的是种植业,最低的是养殖业;发达地区撂荒农地再利用的生态经济效益总体上低于不发达地区;绿色、生态农产品的出售比例,绿色、生态农产品与非绿色、非生态农产品的产值比,政府补贴额度,银行信贷额度,社会服务机构数量,主要农业经营者的文化程度、见识广度等因素对撂荒农地再利用的生态经济效益均产生正向的影响,而年龄则对其产生负向影响。研究结论:政府需要在绿色、生态农产品市场,财政补贴,信用贷款,社会服务机构和吸引优秀农民返乡进行绿色、生态创业上提供政策支持。

Eco-economic Benefits of the Reuse of Abandoned Farmland and Their Influencing Factors: Based on the Survey of 100 Agricultural Enterprises in Guangdong and Jiangxi Provinces

The purposes of the paper are to investigate the eco-economic benefits of the reuse of abandoned farmland and their influencing factors based on the survey of 100 agricultural enterprises in Guangdong and Jiangxi provinces, and to propose the corresponding suggestions. The CCR method in the DEA model was firstly used to measure the eco-economic benefits of the reuse of abandoned farmland, and the semi-log regression model and principal component analysis were further applied to empirically analyze the influencing factors of the eco-economic benefits. The research results show that generally, the highest eco-economic benefit of reusing abandoned farmland are generated by the planting, while the lowest is generated by the breeding. The eco-economic benefits of reusing abandoned farmland in the developed areas are generally lower than those in the underdeveloped areas. The proportion of the sale of green ecological agricultural products, the ratio of output value of green ecological agricultural products to non-green and non-ecological agricultural products, the amount of government subsidies, the amount of bank credits, the number of social service organizations, and the breadth of knowledge and the degree of education of the major agricultural operators have positively effects on the eco-economic benefits of the reuse of abandoned farmland. The age has a negative impact, meaning that the older the operators are, the lower the eco-economic benefits are. In conclusion, the government should provide policy support, such as eco-agricultural market, financial subsidies, credit loans, social service agencies, and should attract the outstanding farmers to return to the rural areas for the green and ecological industries.
