A mathematical model is proposed considering the forest biomass density B(t), density of wood based industries W (t) and density of synthetic industries S(t). It is assumed that the forest biomass grows logistically in the absence of wood based industries, but depletion of forestry biomass is due to presence of wood based industries. The growth of wood based industries depends on B(t), while S(...

The transformation of economic development approach demands to develop high-tech industries, while high-tech industries can’t develop without financial support, in which different financial structures exists differences in the efficiency of high-tech industries development and support. For this reason, this paper firstly theoretically described the mechanism of financial structure’s effect on h...

T bullwhip effect is the phenomenon of increasing demand variability in the supply chain from downstream echelons (retail) to upstream echelons (manufacturing). The objective of this study is to document the strength of the bullwhip effect in industry-level U.S. data. In particular, we say an industry exhibits the bullwhip effect if the variance of the inflow of material to the industry (what m...

The knowledge economy plays a leading role in current socioeconomic development and has changed industrial development. This study addresses whether changes in industrial development have improved the knowledge innovation, technical level, and productive efficiency of industries. Taiwanese industries were typically labor and technology-intensive and policy-oriented manufacturing industries in t...
