Current Situations and Problems of Logistics for Guangxi Fresh Agricultural Products in the New Period and Recommendations

In recent years,Guangxi realized consecutive bumper harvests in fresh agricultural products,leading increase of logistics demand;logistics infrastructure begins to take shape,and logistics of fresh agricultural products takes on diversified development form with wholesale market as main form. However,traditional fresh agricultural products are not selling well and it lacks construction of supply chain; the construction of logistics information system for fresh agricultural products lags behind; organizational level of production and operation of fresh agricultural products is low. Through analyzing current situations and existing problems of logistics of Guangxi fresh agricultural products in the new period( 21 st century),this paper came up with recommendations for developing logistics of fresh agricultural products of Guangxi. Government should increase policy and financial support,build and manage supply chain of fresh agricultural products,accelerate construction of logistics information system for agricultural products,and improve organizational level of logistics of fresh agricultural products,to ensure healthy development of logistics of fresh agricultural products in Guangxi.

Optimal Scheme Selection of Agricultural Production Structure Adjustment——Based on DEA Model; Punjab(Pakistan)

This paper used the modern evaluation method of DEA （Data Envelopment Analysis） to assess the comparative efficiency and then on the basis of this among multiple schemes chose the optimal scheme of agricultural production structure adjustment. Based on the results of DEA model, we dissected scale advantages of each discretionary scheme or plan. We examined scale advantages of each discretionary scheme, tested profoundly a definitive purpose behind not-DEA efficient, which elucidated the system and methodology to enhance these discretionary plans. At the end, another method had been proposed to rank and select the optimal scheme. The research was important to guide the practice if the modification of agricultural production industrial structure was carded on.

Risk Assessment of Agricultural Products Supply-Chain Finance Based on D-S Theory

Agricultural products supply-chain finance, as one of the solutions to the issue of “capital problems” of agriculture, countryside and farmers, has proposed a kind of characteristics model to assess the risk of agricultural production, processing and marketing, which can improve the issue of farmers and enterprises lacking of funds. This model is proposed on the basis of uncertain information processing method of D-S theory and its data combination rules, combined with the “discount rate” correction model, and it includes a risk assessment index system of agricultural products supply-chain finance, fully considering the five aspects of production, processing, marketing, cooperation of supply chain and collateral. At last, a taro supply chain is taken for example. And the risk assessment of its supply-chain finance based on this model has been discussed in detail. And the result has proved that the model and its algorithm are practical and feasible.

农业机械化、农机服务与粮食生产技术效率——基于人口老龄化视角

基于随机前沿生产函数和多值处理效应模型,使用黑龙江省47个村粮食种植农户样本数据,研究农机服务对老龄农户和非老龄农户粮食生产技术效率的影响。结果表明:当前黑龙江省农户粮食生产平均技术效率为57.2%,总体水平偏低,技术损失较大,存在一定的提升空间;非老龄农户更能从现有的农机服务中获益,农机服务未带来老龄农户技术效率的显著提高,但使得老龄农户留在农业生产之中,形成互补关系;在播种和收获环节,农机服务对技术效率的正向影响受到人口老龄化的抑制,原因在于老龄农户倾向于投入劳动替代农机服务,在不同地块之间转移劳作的成本更高。在发展农机服务、扩大服务经营规模的同时,应考虑农业经营主体的经营特征,完善土地流转机制,促进农业适度规模经营与农机服务协调发展。

高标准农田建设参与对农民种粮收益的影响——基于农业新质生产力的中介作用

基于全国10省1032份农户的微观调查数据,使用内生转换回归模型实证分析了高标准农田建设参与对农民种粮收益的影响。研究发现:(1)高标准农田建设参与显著提升农民种粮收益,且平均处理效应表明,参与高标准农田建设可使农民种粮收益提高2.77%。(2)异质性分析表明,相较于小农户,规模户参与高标准农田建设能够提升种粮收益;高标准农田建设参与不仅促进兼业农户增加种粮收益,而且促进纯农户增加种粮收益;相较于非粮食主产区,粮食主产区农户参与高标准农田建设的种粮收益提升效果更明显。(3)机制分析表明,高标准农田建设参与通过提升农业新质生产力水平,从而提高农民种粮收益。据此,鼓励农民积极参与高标准农田建设管理工作,制定出台农户参与高标准农田建设的差异化政策,同时加快培育和发展农业新质生产力,以实现农民种粮收益提升。
