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.

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.

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.

Conversion Margins for the Major Uses of Agricultural Land and Their Variations in Shandong Province, China

It is of practical significance for the decision-making on country food security and farmland protection to analyze the conversion margins for the major uses of agricultural land and their variations. Based on the panel data of wheat, corn, vegetable, fruit, and forests productions from 520 investigated farmer households of 13 investigated villages in Shandong Province from 2003 to 2009, and using Cobb-Douglas production function, the revenue conversion margins can be obtained separately, between different grain-crops (wheat, corn) and different non-grain crops (vegetable, fruit, forests), and the conversion relationship between growing grain( wheat, corn) and going out for non-farm work. The results show that from 2003 to 2009, growing wheat and corn are more economically and reasonably for farmers, compared with growing vegetable, but growing wheat and corn are becoming less economically and less reasonably day by day, compared with planting forests. Moreover, the conversion margin between wheat and fruit shows obvious scissors difference. Just from 2007, farmers' growing fruit became economically and reasonably, but until 2009, compared with going out to work after abandoning farm8land, growing wheat had no economic rationality. From 2003 to 2009, farmers' growing corn is more profitable than growing fruit and going out for non-farm work after abandoning farmland. The subsidies for wheat and corn have increased farmers' comparative income from food production remarkably, but the subsidies cannot change the general tendency that farmers transform food (wheat, corn) production into non-food (especially forests) production. The revenue difference between growing wheat, corn and vegetable and growing fruit and forests is being pulled ceaselessly bigger, and the tendency that farmers transform wheat, corn and vegetable growing lands into fruit and forests growing lands has become increasingly apparent.

Coordinated development of land multi-function space: An analytical framework for matching the supply of resources and environment with the use of land space for ecological protection, agricultural production and urban construction

Based on the carrying capacity of the resources and the environment,this article defines the connotation of the land multifunctional space(LMFS)from three aspects,ecological protection,agricultural production and urban construction,in the new era of land space planning system.Moreover,a framework is constructed for the coordinated development of the multi-functional oriented space to match the use of land space(ULS)with the supply of resources and environment(SRE).Based on this,the technology and methods of comprehensive evaluation,dominance recognition,and matching relationship division functions of the use of land space(FULS)and functions of the supply of resources and environment(FSRE)are discussed.The advantageous functions of the use of land space(AFULS)and advantageous functions of the supply of resources and environment(AFSRE)are also identified in the study area.A LMFS coordinated development system integrating“function position-comprehensive partition-regulation strategy”is proposed.Through the empirical study of Shandong province,we found that,first,the FULS of ecological protection space in the province is mainly found in high value areas,and the FSRE is mainly in low value areas,which has certain complementarity in the space.The FULS of agricultural production space is mainly observed in high value areas,the FSRE is mainly in middle value areas,and the spatial distribution is balanced and staggered.The FULS of the urban construction space and the FSRE are mainly in middle values areas,and the spatial distribution is basically similar.Second,the FULS in the study area is dominated by the single advantage of agricultural production and urban construction,while the FSRE has a relatively balanced distribution of the advantages of ecological protection,single agricultural production and compound advantages of agricultural production and urban construction,and urban construction and ecological protection.The matching between the two is mainly at high and middle levels.Specifically,70%of the province’s land space still has a certain development and utilization potential,and 30%of ULS intensity is close to or exceeds the resource and environment carrying capacity.Third,considering the comprehensive impact of resource endowment,social and economic development and policy and institutional environment on different matching relationships,this paper constructs the land spatial development strategic pattern of“two screens-seven regions-multicore”positioning and“four regions-eight categories”hierarchical area of Shandong at the macro level,and puts forward a differentiated land space development strategy.

技术性贸易壁垒对山东省农产品出口贸易的影响及对策研究--基于贸易引力模型的实证分析

为了测度我国入世后,TBTs对山东农产品出口所产生的具体经济影响,本文选取2010—2020年中国对欧美、东盟、中美洲、日韩等主要贸易伙伴国农产品出口的面板数据,采用实证调查探究TBTs对山东农产品出口量占比、中国制造业出口额占比等的宏观经济影响。研究显示,进口国在前一时期提交的与农产品有关的TBTs产品,对当期山东农产品出口额占比、工业出口额占比等都具有负向效应,即TBTs产品所限制的生产领域越集中于农村生产地区,其负向效应越突出。最后,本文针对当前山东省内农产品交易如何合理避免TBTs的不良影响,分别从政府、行业和企业层面提出具体建议,以供参考。

基于SBM模型的农业环境技术效率分析——以山东省为例

【目的】分析我国当前农业环境规制对农业环境技术效率的影响,加强农业环境规制建设,为提升农业环境技术效率,提供理论依据。【方法】以山东省农业生产为例,在SBM模型和SBM-NS模型的基础上通过构建环境技术效率测算模型,测算环境规制对山东省农业环境技术效率的影响。【结果】环境规制会带来山东省农业平均29.5%的农业环境技术效率下降,但下降有减少的趋势。在考虑环境规制后,有11个地市的农业环境技术效率出现显著下降,从山东省整体看土地投入冗余55.7%,劳动力投入冗余44.8%,资本投入冗余25.4%,二氧化碳过量排放49%。【结论】环境规制会产生农业环境技术效率下降,其根本原因是粗放式的农业生产模式。在山东各市效率下降的具体因素中,土地、劳动力、资本、二氧化碳排放具有不同权重。

SPS措施对山东省农产品贸易影响的实证调研

对山东省28家农产品出口龙头企业进行了问卷调查,发现64.3%的企业受到SPS影响,尤其是以残留限量为主的措施,日本、欧盟和美国市场的SPS影响最大,小型企业所受影响大于大中型企业,内资企业的影响要大于外资企业,贸易型和综合性企业的影响大于生产加工型企业。究其原因,一是SPS措施本身存在着某种程度的歧视性,同时国内外标准的差异以及信息不对称,行业组织不发达也是因素之一,根据调研,政府应主要为企业争取公平待遇、提供有效的信息,建立SPS预警系统、对企业进行有针对性培训等帮助企业提高应对能力。
