Policy Analysis for Strategies of Sustainable Development of Chu-Mango Value Chain in Vietnam

The study is to apply a policy analysis matrix (PAM) and SWOT matrix to identify macroeconomic policy efficiency, establish policy scenarios, and suggest strategic solutions for the sustainability of the Chu-mango value chain. The results prove that macroeconomic policies significantly influence the economic efficiency and competitiveness of export channels (protection of output price, exchange rate, and subsidization of domestic costs). Channel 1 adapts well to changes in macroeconomic policies and maintains economic efficiency and international competitiveness in all scenarios. Channel 2 is strongly affected by free on board (FOB) price policy. It will lose economic efficiency if the FOB price declines by 20%. Another policy from the government is to improve the mango quality of Channel 2 to provide it to Channel 4. It is a policy to develop domestic channel 4 for import substitution. Channel 3 is sensitive dynamic with an output price policy and is a disincentive to export expansion. It only promotes exports when the FOB price increases by 20% or the exchange rate decreases by 20%. The paper also suggests 10 strategies to sustainably improve the Chu-mango value chain. Strategic solutions for upgrading the efficiency of the Chu-mango value chain sustainably are suggested by SWOT analysis from sharing ideas of stakeholders in whole chain. Particularly, the results contribute to the basic principle of the PAM in analyzing comparative advantage and policy efficiency of international trade, especially in the tropical fruits and vegetables field.
