Intellectual capital (IC) is an important source of value for companies. The competitive firm invests in new productive ideas through scientific and technological researches of the human factor and services. The traditional factors of"old economy" based on physical assets have been replaced or at least reinforced, with the belief that the "new economy" takes its steps mainly through IC. The knowledge workers, at every organizational level, have the knowledge that allows the organization to be competitive and deal with the complexity of the environment by creating intellectual added value. In particular, the proposed analysis consists with an empirical way to show other financial indicators and market-to-book (MTB) value from the perspective of creating value for shareholders based on the dynamics of companies' performance, as value-added intellectual capital (VAICTM) is capable of expressing a direct relationship with the return on equity (ROE). The traditional financial information cannot ensure the high efficiency of a stock market and the need for IC reporting to explain intangible asset contribution in company performance. 展开更多

To date, there are many taxes implemented by the ruling authorities of a country. The taxes that are sourced from stock markets or share markets are paramount to better govern a country. The capital gain tax (CGT), which is incurred in disposing the shares or stocks owned by an investor or an institution, is one of the taxes implemented in stock markets. Though in the past many attempts have been made to properly streamline the CGT, the methodologies or the approaches used in the implementation of CGT, even in the United States, are not well-grounded from a scientific point of view. Therefore, in this paper, a simplified approach based on the assumption that the CGT is implemented on a yearly basis is proposed. The CGT is calculated for each stock owned by an investor or an institution. The approach is implemented using an open access platform: AMP (Apache-MySQL-PHP). Subsequently, the proposed approach is tested using some hypothetical data. The proposed approach, which is easy-to-use, practical and un-biased, is of use to any country that is willing to progress towards the sustainability. Moreover, the proposed approach with the current technology will enhance the developing nations which have large size of informal economy, on designing and implementing effective tax policies and administrations. 展开更多

A stock exchange is an exchange where stock brokers and traders can buy and sell shares of stock, bonds, and other securities. All listings are included in the Nigerian Stock Exchange All Shares index. In terms of market capitalization, the Nigerian Stock Exchange is the third largest stock exchange in Africa. Objectives: The paper assesses the impact of Nigerian Stock Market (all share index, market capitalization, and number of equities) on Gross domestic product (Economic Growth). Materials and Methods: Regression analysis and ordinary least square technique were employed. Result and Discussion: The series was stationary at 1%, 5%, and 10% α level;the residuals were normally distributed but not serially correlated at 5% α level. All Share Index, Market Capitalization and Total Number of listed Equities have a joint and individual significant effect on Economic Growth (Gross Domestic Product) with Total Number of listed Equities having a negative (opposite) linear relationship with the Gross Domestic Product. The Durbin-Watson statistics (R2 = 0.9910 = 1.3686) suggest that the model is not spurious and it is devoid of positive and negative autocorrelation (DW = 1.3686 > dl = 1.07 and DW = 1.5033 ?-?du = 2.17). Therefore, it can produce meaningful result when used for forecasting a positive relationship between gross domestic product, all share index and market capitalization with a 99.1% R-square value. Significant Positive connection between all share index, market capitalization, the number of equities and gross domestic product suggests that government policies and bills aimed towards rapid development of the capital market should be initiated. 展开更多

Using sector-specific growth accounting method, this paper investigates the growth effect of inter-industry allocation of capital and labor in China. This paper has found that existing investment data are classified according to investment entities rather than user entities and directly using such data for the measurement of capital inventory of various sectors will seriously overestimate the capital inventory of tertiary industry and lead to distorted conclusions of "structural burden" of capital allocation and its serious violation of the principle of efficiency. By excluding real estate sector, this paper has found that after the 1990 s, inter-industry capital allocation had been generally consistent with the principle of efficiency and the effect of capital allocation structure is not significant. Our estimates also found that the growth effect arising from the inter-industry allocation of labor since reform and opening up averages 0.63 percentage points, which is significantly positively correlated with residual economic growth rate and residual TFP and demonstrates a decade-long "reform cycle." According to the comparative study on the effect of labor allocation structure of 37 other countries and regions, by 2017, the effect of China's labor allocation structure will continue to remain in a relatively high stage; between 2017 and 2023, structural effect will significantly diminish and deceleration pressure will rise swiftly; after 2030, the effect of labor allocation structure will linger in a low level stage, when economy is likely to enter into a stage of low growth rate. These findings will help us better assess future economic growth tendencies. 展开更多

Pressured by a slowdown in exports, cost increases and dwindling returns to manufacturing investments, China's manufacturing capital has begun to shift to the real-estate and stock markets. As a matter of fact, the stock market had already felt a shock a couple of years ago when top domestic manufacturers like Midea, Gree, TCL and LMZ started to invest their idle capital in the real-estate and stock markets. Investments of manufacturing capital in both the real estate and stock markets have increased fluid capital and pushed up the value of both markets. Booms in both markets have in turn guaranteed investment returns of manufacturing capital, which further increased the stock market valuations of manufacturing capital. Such a cycle has created interest chains between listed manufacturers, the stock market and the real-estate market. Along with the ups and downs of the stock and real-estate markets, manufacturing capital now faces a dilemma: to escape or to persist? Where should it escape? When can the markets be profitable again? Just like the classic Shakespearean question: to be or not to be, that is the question. 展开更多

This paper aims to examine the market development evolution of Lao Securities Exchange (LSX) by observing the institutional structure, securities regulations, and government’s policy and utilizing the annual data of market indicators from 2011 to 2017 through the regression model in order to determine the facing issues with proposing the resolution implication for securities exchange development. The finding of this paper also concludes that the liquidity issue, small number of listed firms, undiversified products, small investor base, insufficient legislation from regulatory body, and slow progress in transforming state-owned enterprises (SOEs) into public companies are the current pressure obstacles for securities market development in Laos. In this case, there is a need for stronger commitment from government in securities market development by closer collaboration among line ministries, enlarging the investor base to public and private sectors, acknowledging the significance of drafting the public company act, and persuading the SOEs to issue initial public offering (IPO) in LSX, as the result would drive positive impacts to stimulate the capital market development in Lao People’s Democratic Republic (Lao PDR). 展开更多

The primary objective of the cash flow statement is to provide useful, meaningful, and relevant information about the cash receipts and cash payments of a firm during a given period of time. Decision makers can achieve extra features of the change in net assets, the firms' financial position (liquidity and solvency), and the firm's ability to adapt to changing circumstances by affecting the amount and timing of cash flows. Cash flow statements improve comparability as they are not affected by differing accounting policies used for the same type of transactions or events. This study aims to verify the effect of net working capital (NWC), as an indicator of a company's short-term liquidity or its ability to meet short-term obligations, on Jordanian industrial and energy sectors' net operating cash flows (NOCF). A simple liner regression is used to test a period of 2008-2011 in order to conclude the extent of the effect on industrial and energy sectors. The study showed that there is a significant effect of the independent variable NWC on the dependent variable NOCF among industrial and energy sectors in Jordanian market. Whereas the adjusted R-squared of test is 0.854, changes in NOCF in Jordanian industrial and energy sectors have been described by NWC. Also, the study reached that the utilities and energy sector has the lowest NWC, while the mining and extraction sector has the highest. And, electrical industries sector has the lowest NOCF, while the mining and extraction sector has the highest. Moreover, the study showed that the printing and packaging sector has the lowest NWC, while the mining and extraction sector has the highest. And, glass and ceramic industries sector has the lowest NOCF, while the utilities and energy sector has the highest. 展开更多

On March 31,2010,China formally introduced a margin trading system,which announced that China's capital market has completed the transformation from a unilateral transaction model to a bilateral transaction model with a short-selling mechanism.However,the current development of China's margin trading and securities lending businesses is seriously unbalanced,and the scale of financing far exceeds the scale of securities lending.The short selling effect of securities lending exchanges is extremely limited,which to some extent violates the original intention of introducing the system.In order to help margin trading and securities lending to correct a healthy and sustainable development path,this article uses stock price synchronicity as a proxy indicator to measure the information efficiency of the capital market,explores the impact of the margin trading system on the information efficiency of the capital market,and study the detailed characteristics and economic consequences of the margin trading system.Aiming at this topic,this article analyzes the relationship between margin financing and securities lending and stock price synchronicity.Finally,it analyzes the influence of margin financing and securities lending system on stock price synchronicity from three dimensions of corporate governance,external supervision,and institutional environment mechanism.In terms of empirical research,this article takes advantage of the“quasi-natural experiment”provided by the gradual opening of margin trading and securities lending in China’s securities market,and selects listed companies on the Shanghai and Shenzhen stock exchanges from 2007 to 2019 as the research objects,starting from the perspective of stock price synchronicity,and passing The DID-FE model studies the impact of the margin trading and securities lending system on the information efficiency of the capital market.It uses three methods:parallel trend and dynamic testing,PSM-DID analysis,and placebo testing for robustness testing to solve the endogeneity problem of the experiment.This article also conducts deeper research on the subject based on the two dimensions of the impact mechanism of margin financing and securities lending and the size of the company,and finally discusses the economic impact of margin financing and securities lending on the level of company innovation. 展开更多
