Costed Action Plan for SADC Industrialization Strategy and Roadmap b) Private-Public Interface Without close public-private collaboration in the realm of industrial policy, there is a danger that policymakers will launch well-intentioned but poorly designed or even ill-advised industrialization strategies. Textbook learning or donor advice is no substitute for in-house and first-hand knowledge, experience of technological, and market conditions. The “discovery” process in value chain policymaking is heavily reliant on close co-operation between the public and private sectors. Improved management information on both sides is crucial to efficient and effective decision making. c) Constraints The national reports and case studies consulted pinpoint infrastructure – both physical (hard) and institutional and scope economies (soft) – as critical constraints in value chain development. In agriculture value chain developed is impeded by poor transport, storage and marketing facilities, along with insufficient or tardily available information. Similarly, the case studies highlight the scarcity of essential skills and invariably finance. 3.8 Policy-mix in Support of Value Chain Participation The Strategy proposes a stronger focus on ensuring that macroeconomic policies support inclusive growth, economic diversification, enhanced competitiveness, and promote regional integration. This will require private sector investment in the productive sectors of national and the regional economy, in close coordination and cooperation with Member States. To this end the specific actions proposed are the following: (i) Ministries and departments responsible for trade and industry and the relevant fiscal and monetary authorities should consult closely on the use of macroeconomic and industrial policy instruments to facilitate accelerated industrial development. (ii) That Member States put in place macroeconomic policy regimes that aim at achieving inclusive growth; economic diversification and competitiveness; deeper regional integration; and macroeconomic policy convergence. (iii) The key policy recommendation of value-chain development is working with and supporting industry players and investors to occupy higher value-adding segments of the production chain. In that regard, the IUMP is an important tool in supporting the development of productive capacity, enhancing the competitiveness of SMEs and the strengthening of regional value chains. 38
