  2. In the 3rd chapter, the author not only analyzes the theory but also does research on the practical status of information flow and logistics of every region of china. the author draws a conclusion as follows : with regard to the whole country, more advanced information technology of a region is, less logistics requirement per unit is needed, i. e., less logistics cost ; meanwhile, in coastal region with advanced information flow, the role of replacement of logistics requirement taken by information flow is obviously greater than the role of promotion ; in the last, this article analyzes the current status of information flow and logistics in supply chain of china and indicates that the existing problem is that information flow in supply chain is not fluent enough to support effective operation of logistics, and finds out the obstacle to the harmonious object implementation of information flow and logistics

    在第三章中，作者不僅對理論問題進行分析研究，還對中國各地區實際的信息流與物流情況進行比較分析，找出其中的規律：即從全國范圍看，信息化越發達的地區，單位貿易量所需的物流需求量越少，即所需物流成本越低；並且在信息流發達的沿海地區，信息流對物流需求量的替代作用明顯大於信息流對物流需求量的促進作用；最後本文分析了中國供應鏈中信息流與物流的現狀，發現目前存在的主要問題就是供應鏈中信息流的不暢通嚴重影響了物流運作效率，並找出影響信息流與物流協調目標實現的障礙，最後從宏觀和微觀兩方面提出供應鏈信息流與物流協調目標實現的途徑與對策。
