Production Chain Length and PPI-CPI Divergence:Analysis Based on the Global Input-output Price Model

Productivity and international energy price shocks are reflected in PPI and CPI via industrial chains.China’s in-depth participation into the global value chains has increasingly lengthened its industrial production chains.The question is how the changing length of production chains will affect CPI and PPI,as well as CPI-PPI correlation?By constructing a global input-output price model,this paper offers a theoretical discussion on the impact of production chain length on the CPI-PPI divergence.Our findings suggest that the price shock of international bulk commodities has a greater impact on China’s PPI than that on CPI.The effects on both China’s PPI and CPI estimated by using the single-country input-output model are higher than the results estimated with the global input-output model.However,the difference between CPI and PPI variations estimated with the global input-output model is greater than the result estimated with the single-country input-output model,which supports the view that the lengthening of production chains,especially international production chains,leads to a divergence between CPI and PPI.Empirical results based on cross-national panel data also suggest that the lengthening of production chains has reduced the CPI-PPI correlation for countries,i.e.the lengthening of production chains has increased the PPI-CPI divergence.That is to say,policymakers should target not just CPI in maintaining price stability,but instead focus on the stability of both PPI and CPI.Efforts can be made to proactively adjust the price index system,and formulate the industrial chain price index.

Researches on Risk Evaluation of Green Agro-product Closed Supply Chain

Closed supply chain is a superior form of management model of chain supply and an effective means of improving the modernization of agro-product circulation. Based on the research results of the current literatures on supply chain risk and agro-product supply chain, related subjects of the agro-product closed supply chain involving production, management and consumption are studied and analyzed and the primary risking factors in the supply chain system are classified as environmental risk, system risk, information risk, management risk and quality risk. Risk of agro-product closed supply chain is evaluated by using the method of fuzzy comprehensive evaluation and the values are acquired. The result shows that risk of agro-product closed supply chain is moderate with relatively high risk, which basically accords with the present actual situations. It can be seen from the index weights of various levels that the key first-level indices influencing the risks are system risk, information risk, quality and safety risk and the key second-level are the coordinating and controlling ability of core enterprises, the implementation of information traceability and the construction of quality safety system. Therefore, risk of agro-product closed supply chain should be reduced by taking prevention and controlling measures mainly from these aspects.

The Decision-Making Processes of the Agents Belonging to the Biodiesel Production Chain in Southern Brazil

The aim of this paper is to present and analyze the factors, motivations and criteria considered in the decision-making processes of the actors belonging to the biodiesel production chain in Brazil. The biodiesel production chain consists of three main agents： the farmers, the soybean processing plants and the oil refinery/distributor. For the farmers organized in cooperatives the central decision is whether to sell oil-bearing crops for the production of biodiesel. In contrast, for the soybean processing plants that convert the crops into vegetable and/or biodiesel, the decision to produce this fuel is based on the wish to expand their market portfolio. Government tax incentives strongly influence both decisions regarding which oil-bearing crop to use and the amount of vegetable oil to be transformed into biodiesel. Finally, the oil refinery/distributor is obliged by law to mix the biodiesel with the mineral diesel and perceives this as a liability. The results show the existence of different characteristics linked to the decision-making process and a significant lack of synchronicity in the aims and motivations behind the agents＇ decisions. This state of decisional misalignment leads to heightened uncertainty regarding the sustainability of the Brazilian biodiesel production program.

Toward Establishing the Productive Chain for Triterpene-Based Amazonian Oleoresins as Valuable Non-Timber Forest Products

In the Amazonian rainforest, many species of Burseraceae known locally as “breu” are explored for the medicinal and aromatic uses of their trunk exudates. This material also has a long-standing use by the forest communities in building and caulking boats as well as in the making of wooden utensils and general crafts. Breu are strongly aromatic due volatile terpenes in their composition that are separated from the crude resin by steam distillation. The remaining residue amorphous “hard resin” is primary used for application in woodworking. Despite the potential for application in paints, varnishes and odor fixatives, the commercialization of the hard resin has not surpassed the local market level. In order to achieve and establish a more valorized market for this Amazonian non-timber forest product, the existing and potential demands need to be estimated, a draft of the production chain needs to be drawn up and care needs to be taken to provide products of the highest possible quality. This study aimed to identify and organize the main issues necessary for the attainment of these goals and its value chain, and identify the technologies that would improve the quality of the Amazonian breu as a raw material. A review of the data available in the literature and the analytical techniques that could be applied to generate standards for the extraction, purification, and analysis of the hard resin fraction was made. Quality issues based on physicochemical standards might affect the productive chain by: i) helping to consolidate the appropriate methodologies for collecting and storing the raw material;ii) adding value and qualifying the primary improvement processes and iii) supporting the certification of the raw materials for commercialization. Potentiate this material to reach high-level markets might boost the production demand and improve the rain forest communities’ income.

ANTIBODY TO ONCOGENE PROTEIN PRODUCT AND ITS CONJUGATE WITH RICIN A-CHAIN

The proteins encoded by oncogene were thought to be tumor associated antigen. The protein P110 in MGC803, a human gastric cancer cell line, was purified as immunogen. The IgY to the gastric cancer was extracted from eggs laid by immunized hen. The IgY could react immunohistochemically with gastric cancers. Positive staining rates of PAF were 80% in gastric cancers and markedly higher than in cancers of other organs and normal gastric tissue. The IgY-Ricin A was synthesized by the IgY conjugated with Ricin A- chain. TCID50 of MGC803 treated by the IgY-Ricin A was 0. 01 mg/ml and markedly lower than other cell. These results showed the IgY-Ricin A were able to react with gastric cancers selectively.

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.

Markov Chain for Reuse Strategies of Product Families

A methodology is presented to plan reuse strategies of common modules in a product family by using the concepts of function degradation, reliability, function requirement, cost and life time. Markov chain model is employed to predict function degradation and reliability. A utility model is used to evaluate the preference between used modules and new modules. An example of cascading-requirment product family illustrates the main ideas of our work. The Markov models are used effectively to predict function degradation and reliability. Utility theory is helpful to evaluate the reuse options of common modules.

Market and Value Chain Analyses of Marketable Natural Products from Agroforestry Systems in Eastern Sudan

The objectives of the present study were: 1) to identify the prioritized marketable natural products (NPs) from agroforestry systems (AFS), and 2) to conduct market value chain analyses of the most important and prioritized NPs to identify markets and marketing channels;actors, functions and characteristics;constraints and opportunities to entry and growth;opportunities for value addition, and conduct analysis of strengths, weaknesses, opportunities and threats (SWOT analysis). The study was conducted in the Refugees’ camps and their hosting communities in Eastern Sudan. Using the participatory value chain analysis (PVCA) approach, it was found that communities in the project sites obtained a multiplicity of NPs for sustenance and for increasing their incomes. Eight products were identified and ranked as the most important NPs with greatest opportunities for enterprise development at the community level. These are: gum Arabic, honey, fodder, non-timber forest products (NTFPs) and tree seeds. Gum Arabic has been shown to score higher ranks in terms of a) marketability b) ecological suitability (availability), c) social suitability, and d) potential for value addition. The results show that marketing of gum Arabic in the study site is characterized by a large number of producers and relatively few traders and companies work through seven marketing channels. The results demonstrate that in the customary marketing channel there is an upward skewed benefit distribution among the value chain actors. The total relative commercialization margin was 80% indicating that “traders” accrued higher proportion, while “producers”, receive less income (20%) of the end market price. Poor land security, one-sided prices, taxes and levies, lack of finance and appropriate skills are major impediments to gum commodity growth and development. One of the most important opportunities for growth and entry of Gum Arabic are: it is natural organic product and thus well-fit for fair trade, environmentally sustainable and organic market development. Numerous opportunities exist in the site for value addition and distribution synergies and gender-specific development, including that gum Arabic has high synergy with natural resource management and other sectors for enhancing regional and national growth. The study concludes that Gum Arabic production and marketing is financially profitable for producers, traders and companies and has the potential to open new markets and bring new opportunities to smallholder farmers. However, technical, financial, and institutional support could result in an increase in local actors’ income and contribute to sustainability of the supply of the product.
