Since the 21st Century, China has become increasingly closely related to Latin American countries， and economic and trade cooperation has also increased rapidly. However, there exist various barriers in the process of cooperation between the two sides. Based on the data and descriptive statistics concerning economic and trade cooperation, this paper analyzes barriers, propose countermeasures, and the prospects of the future relationship between China and Latin America.

The classical economists have mostly focused their attention on the functioning of the market and not on the role of the state. The analyses of various democracies are based on the assumption that the State decisions once made are applied as intended by the authorities who are responsible for their practical implementation. The economics of regulation is situated at the intersection of the public economics and industrial economics, it explores different forms of government intervention in industrial activities to simulate either to control or even to reprove them. Public intervention can take different forms: in Europe the most common practice is the nationalization, it is the public monopoly of law. In the United States operation of this natural monopoly is assured through economic regulation, that is to say all means by which Governments directly influence the activity of companies while maintaining the framework of the private property. It is very important to distinguish between the economic regulation of an activity that focuses on the price and the determination of the structure of offer, and the social regulation concerning the conditions for the exercise in the activity and the physical characteristics of the products or services (protection of workers in their working conditions (health, security), rules of environmental protection or standardization of products (quality).

The study empirically examined the determinants of share price in the Nigerian Stock Market from 1980 to 2000. Data from fifteen quoted companies were used. The study adopted ordinary least square method i.e multiple regression to analyse and interpret the data that were mainly sourced from the Nigerian Stock Exchange. The model used expressed the share price as a function of some identified determinant established by theories and literature. These determinants are earning per share, dividend per share, money supply, oil price, the gross domestic product, consumer price index and interest rate. After the analysis it appears that all these variables are true determinants of the share price in Nigerian Stock market going by the significance of the model at both 5% and 10% levels of significance and the robustness of the R square which stood at about 0.93. This simply shows that these identified determinants have been able to explain about 93% variation in the share price of the companies. However based on the revelations concerning the relationship of the share price and each of this variables it appears the that earning per share, dividend per share, money supply, oil price and consumer price index all exhibited positive relationship with the share price while interest rate and GDP exhibited negative relationship.

The study empirically investigate the nexus between agricultural financing and economic growth in Nigeria from 1983 to 2015. Augmented Dickey-Fuller (ADF) test and the Phillip-Perron tests were used to establish which variable is stationary at different levels. Almost all the variables (Real Gross Domestic Product (RGDP) Agricultural credit guarantee scheme fund (ACGSF) Commercial Bank Loan and Advance on Agriculture (CBLAA) are stationary at first different form, that is they are integrated of order I (1) except interest rate (INTR) which is stationary at level, that is, it is integrated of order I (0), hence Bounds co-integration test was adopted since it allows combination of fractionally integrated variables i.e. combines variables of different orders of integration. The results reveal existence of long-run relationship between proxy of economic growth and the proxies of agricultural financing. Meanwhile, Auto Redistributed Lag (ARDL) results show both short and long run effect of agricultural financing schemes on the growth of Nigerian economy. In addition, various diagnostic tests (such as Jarque-Bera (JB) test, Breusch-Pagan Serial Correlation (LM) test, Ramsey test, and ARCH test) were conducted to fulfill some of both Ordinary Least Square and normality assumptions. Notably, the loan disbursement mechanism adopted by agricultural credit institutions have fail to drive the Nigerian economy towards real growth despite the long run nexus among the key variables, coupled with corruption, and policy summersaults in the sector. Therefore, there is need for proper channelization of loans across board with sustainable fiscal measures that can translate to actual growth.
