区域经济协调发展的协调机制与制度激励——以苏南、苏中、苏北为例

Regional Economic Coordinated Development on the Basis of Coordinated Mechanism and Systematic Encouragement——Taking southern,central and northern Jiangsu as an example

区域经济协调发展是实现整体利益最大化目标的一种手段和过程。在这样一个过程中 ,作为区域利益的总代表 ,各区域政府的行为逻辑肯定是利己而非利他的 ,因此 ,尽管各区域政府的自协调也是协调机制的一部分 ,但往往无法实现整体利益的最大 ,甚至连个体利益的最大也无法实现。中央政府的目标函数是整体利益最大化 ,其战略选择可能是梯度发展 ,也可能是平衡发展。但这不取决于主观意志而取决于客观条件。理性的选择肯定是把边际投资回报率高的地区和行业作为投资的重点。由于这并不是一个“0 - 1”分布的问题 ,所以 ,随着发达地区边际投资回报率的递减和不发达地区边际投资回报率的递增 ,中央政府应该逐渐减少对发达地区的投资和增加对不发达地区的投资 ,最终过渡到把投资重点完全转移到不发达地区 ,实现由梯度发展战略到平衡发展战略的转移。

The integrated interests on a full scale can be made on the basis of the coordinated development of regional economy.Chiefly representing the regional interests,the local governments aim at their own benefits rather than others as the code of their conductions.Therefore,the self coordination of local governments makes it impossible to achieve their integrated maximum interests as well as their own individuals.The objective functions of the central government is the overall interests on a full sale,thus the grading or the balanced development must be the strategic goal that the central government tends to reach on the basis of objective conditions rather than subjective willings.It is a rational decision to take the regions and industries with high return rate on marginal investment as the investment orientation.Due to the fact that the return rate on marginal investment is decreasing progressively in developed areas and increasing progressively in undeveloped areas,the corresponding investment from the central government is expected to be reduced or increased relevantly along proper lines.Finally the orientation of total investment will be changed to the undeveloped areas so as to make the strategic shift from grading development to balanced development.
