To address the first issue, I draw an important distinction between international investment banks and multinational investment banks. For an international investment bank to be regarded as a multinational, I propose that it must have a strong presence (i.e., holding at least one percent of the market share) in at least two of the seven major capital markets in the world. Using this criterion, I identify 25 multinational investment banks. I then analyze their home countries’ domestic market conditions and propose that the following six factors are important to the development of multinational investment banks: the size of the home country’s gross domestic product (GDP), the total capitalization of its domestic security market, the number of its Global 500 firms, the volume of its foreign direct investment (FDI), the internationalization of its currency, and the openness of its capital market to foreign investors.
By comparisons, I find that China’s domestic market conditions are comparable to the home countries of multinational investment banks with respect to the size of GDP, total market capitalization, the number of Global 500 firms, and the volume of FDI. What China lags behind are the internationalization of currency and the openness of capital market to foreign investors. Given the current trends of development, it is very likely that China will be able to catch up on the latter within ten years, thus meeting all the conditions necessary for the development of multinational investment banks.
Based on the above findings, I suggest that Chinese investment banks seize this historical opportunity, speed up the internationalization of their businesses, and learn from the experiences of global industry leaders to become truly multinational corporations.
This thesis is organized as follows. First, I provide a brief description about the emergence and development of China’s guarantee industry, as well as its current status. Next, I explain what kinds of risks faced by guarantee firms in China that influence their performance and survival, and summarize the various external and internal risk factors. I also conduct one in-depth case analysis to illustrate how a guarantee firm can better identify the risks it is exposed to. Next, on the basis of another in-depth case analysis, I develop a framework that can help guarantee firms to systematically develop effective measures of risk identification and prevention. I conclude with a discussion of this study’s implications for guarantee firms and the regulatory governmental agencies in China.
On the basis of prior research findings and the current situation of the Chinese securities industry, I first develop a theoretical model about the sources of competitive advantage for Chinese securities companies, and then compile a comprehensive list of observable indicators that can be used to assess a Chinese securities company’s core competency. Next, I conduct a quantitative analysis to assess the core competency and relative market positions of the leading Chinese securities companies using data from 2010 to 2014. Overall, the results suggest that market-driven M&As increases the core competency of the acquiring securities companies. I then conduct four in-depth case analyses to better understand the mechanisms through which M&As can help increase the acquiring firms' core competency. I conclude with a discussion of the findings and their implications for Chinese securities companies and the overseeing governmental agencies.
To address these challenges, this thesis presents a formal approach to designing biologically-inspired swarm control strategies for spatially-confined coverage and payload transport tasks, as well as a novel low-cost, customizable robotic platform for testing swarm control approaches. Stochastic control strategies are developed that provably allocate a swarm of robots around the boundaries of multiple regions of interest or payloads to be transported. These strategies account for spatially-dependent effects on the robots' physical distribution and are largely robust to environmental variations. In addition, a control approach based on reinforcement learning is presented for collective payload towing that accommodates robots with heterogeneous maximum speeds. For both types of collective transport tasks, rigorous approaches are developed to identify and translate observed group retrieval behaviors in Novomessor cockerelli ants to swarm robotic control strategies. These strategies can replicate features of ant transport and inherit its properties of robustness to different environments and to varying team compositions. The approaches incorporate dynamical models of the swarm that are amenable to analysis and control techniques, and therefore provide theoretical guarantees on the system's performance. Implementation of these strategies on robotic swarms offers a way for biologists to test hypotheses about the individual-level mechanisms that drive collective behaviors. Finally, this thesis describes Pheeno, a new swarm robotic platform with a three degree-of-freedom manipulator arm, and describes its use in validating a variety of swarm control strategies.
Firstly, the essay analyzes the relationship between the universities education and the supply and demand labor market by using the view of labor economics, and shows the mainly phenomenon and features of supply-demand imbalance. And then, the writer considered that universities talent cultivation development of China has gone through “absolute shortage”, “relative shortage” and “structural unbalanced” three stages. Thirdly, the survey results confirmed that the talent cultivation in universities does not match the demand of the labor market. On one other hand, over educated is a common phenomenon in the academic education. On the other hand, the graduates are lack of education skills training. Fourthly, the essay analyzes the reasons which lead to the unbalance. The unbalance is not only affected by the macro factors, but also by the micro factors. Fifthly, build up the interaction system model “UPT-LM” for the universities talent cultivation and the labor market, and separately building up the macro interaction system and the micro interaction system to analyze the balance of supply and demand. Based on this, it should strengthen the interaction on the feedback mechanism. At last, strengthening the connection of universities talent cultivation and labor market is a systematic program which needs the corporation from the government, the universities and the labor market.
A passive and a powered ankle joint system is developed and fit to the field of prosthetics, specifically ankle joint replacement for able bodied gait. The general 1 DOF robotic joint designs are examined and the results from testing are discussed. Achievements in this area include the able bodied gait like behavior of passive systems for slow walking speeds. For higher walking speeds the powered ankle system is capable of adding the necessary energy to propel the user forward and remain similar to able bodied gait, effectively replacing the calf muscle. While running has not fully been achieved through past powered ankle devices the full power necessary is reached in this work for running and sprinting while achieving 4x’s power amplification through the powered ankle mechanism.
A theoretical approach to robotic joints is then analyzed in order to combine the advantages of both passive and powered systems. Energy methods are shown to provide a correct behavioral analysis of any robotic joint system. Manipulation of the energy curves and mechanism coupler curves allows real time joint behavioral adjustment. Such a powered joint can be adjusted to passively achieve desired behavior for different speeds and environmental needs. The effects on joint moment and stiffness from adjusting one type of mechanism is presented.
