Financial Development,Economic Growth and Adaptive Efficiency:A Comparison between China and Pakistan

The strong economic growth in China is difficult to reconcile with its inefficient financial system. The puzzle of China＇s financial development and growth can be explained through a dynamic criterion of adaptive efficiency, rather than through allocative efficiency. Using the framework of an autoregressive distributed lag model, the present paper tests the hypothesis that the GDP growth rate is dependent on financial development along with other variables in China and Pakistan. The hypothesis cannot be rejected in both cases. However, the results show that economic growth has a negative relationship with credit to the private sector in China. We conclude that financial development is a source of China＇s high growth rate and that the banking system is still under an evolutionary process, involving the pursuit of social objectives instead of the sole objective of profit maximization. Our results provide some implications for other developing countries like Pakistan.

Refining the Art of Reforming the Corporate Governance of Chinese State-Controlled Listed Companies： Venture Capital and Adaptive Efficiency

The corporate governance of Chinese state-controlled listed companies （SCLCs） has attracted much scholarly attention. Through reviewing the extant literature in this field, it is clear that the overwhelming majority is theoretically underpinned by the lens of agency costs. Another important perspective, adaptive efficiency, has yet to be equally emphasized by scholars. Reflecting on the experience of American venture capital （VC）, this article puts forth that the corporate governance of SCLCs has weakened the fundraising ability of Chinese domestic VC. Taking account of the positive link of a vibrant VC sector and the enhancement of adaptive efficiency, an obvious conclusion is that the corporate governance of SCLCs has already jeopardized the adaptive efficiency of the Chinese economy. Further, the normative implication of this finding is that the refined art of reforming the corporate governance of SCLCs ought to combine and harmonize agency costs with adaptive efficiency.

Adaptive Energy-Efficient Power Allocation for DAS with Imperfect Channel State Information and Antenna Selection

Considering that perfect channel state information(CSI) is difficult to obtain in practice,energy efficiency(EE) for distributed antenna systems(DAS) based on imperfect CSI and antennas selection is investigated in Rayleigh fading channel.A novel EE that is defined as the average transmission rate divided by the total consumed power is introduced.In accordance with this definition,an adaptive power allocation(PA) scheme for DAS is proposed to maximize the EE under the maximum transmit power constraint.The solution of PA in the constrained EE optimization does exist and is unique.A practical iterative algorithm with Newton method is presented to obtain the solution of PA.The proposed scheme includes the one under perfect CSI as a special case,and it only needs large scale and statistical information.As a result,the scheme has low overhead and good robustness.The theoretical EE is also derived for performance evaluation,and simulation result shows the validity of the theoretical analysis.Moreover,EE can be enhanced by decreasing the estimation error and/or path loss exponents.

Control method on serial type pump-valve coordinated electro-hydraulic servo system

In order to compromise the conflicts between control accuracy and system efficiency of conventional electro-hydraulic servo systems,a novel pump-valve coordinated electro-hydraulic servo system was designed and a corresponding control strategy was proposed.The system was constituted of a pumpcontrolled part and a valve-controlled part,the pump controlled part is used to adjust the flow rate of oil source and the valve controlled part is used to complete the position tracking control of the hydraulic cylinder.Based on the system characteristics,a load flow grey prediction method was adopted in the pump controlled part to reduce the system overflow losses,and an adaptive robust control method was adopted in the valve controlled part to eliminate the effect of system nonlinearity and parametric uncertainties due to variable hydraulic parameters and system loads on the control precision.The experimental results validated that the adopted control strategy increased the system efficiency obviously with guaranteed high control accuracy.
