Specially, the author hopes to find whether the financial system development promotes the provincial per capita, the accumulation of provincial savings, the formation of provincial capital, the advancing of productivity, the bettering of industrial structure and the shaping of firms. Finally, according to the result of the empirical study, the author brings forward the Contradiction of Chinese Financial System Development during transition period. To explain the Contradiction, the author puts forward a hypothesis: time consistency and institution coupling of the optimal system arrangements. Within the hypothesis framework, the author analyses and explains the contradiction's essential, and seeks the reason of Chinese financial system development's path formation during transition period. After judging the efficiency of Chinese financial system development prudentially, the author gives his advices on how to drive Chinese financial system to the"Growth-Enhancing Financial System Development"path. The dissertation is divided into five chapters. It consists of as follows: Part I includes foreword and Chapter One"the review of financial development theory and literature". In foreword, the author expounds the fundamental definition and basic theory. In Chapter One, the author first analyses the"finance-growth"nexus in theory, and which constitutes the foundation of the concrete mechanism of finance affecting growth.

Aimed at 9-degree of freedom hyper-redundant module robot in intra-vehicular robot system, attention is given to the avoiding joint limits as an optimal mark. Two different iterative algorithms considering fault-tolerance for trajectory planning of redundant robot in Cartesian space are then proposed by using the method of differential locomotion. The first algorithm is for linear-path in which the pose of manipulator can be changed, the second is for circular-path in the plane decided by three noncollinear arbitrary points in the space. Experiments on the specimen robot platform are performed to validate the above algorithms.
