TFP growth may derive from both technology progress(technical effect) and factor allocation(structural effect). Using China's macroeconomic and industrial data, this paper decomposes China's TFP growth on the basis of growth accounting to cast light on China's growth sources since reform and opening up in 1978. Our study has led to the following findings:(1) From 1978 to 2014, China's economic growth was of generally good quality, and about 1/3 of growth momentum stemmed from a general technology improvement.(2) After 2005, China's late-mover advantage diminished due to narrowed technology gaps with advanced economies. This resulted in a sharp decline in the contribution of technology progress to growth. However, structural effect contributed a steadily increasing share to China's growth.(3) After global financial crisis in 2008, there has been a tendency of reverse technology progress in terms of factor allocation in sectors with excess industrial capacity and other sectors like finance and real estate. Therefore, China should divert its factor resources to more tech-intensive and efficient sectors in the short run, and strive to promote technology progress in all sectors in a longer timeframe. 展开更多

As a unique environmental regulation in China,the official accountability audit was piloted in 2014.With a focus on prioritizing the ecological environment,officials in pilot districts have implemented economic construction,adjusted industrial structures,and promoted coordinated development between the economy and environment.The effects of implementation have garnered widespread attention from society.However,there is limited research on the impact of an accountability audit on industrial structure adjustments.Using the“Accountability Audit of Officials for Natural Resource Assets(Trial)”released in 2015 as a quasi-natural experiment,this study collected panel data from 279 cities between 2013 and 2017.It then empirically analyzed the impact mechanism and effects of the accountability audit on industrial structure adjustment using the Propensity Score Matching and Difference-in-Differences model.The research findings indicate that the accountability audit directly impacted industrial structure adjustment,promoting the upgrading of the primary industry to the secondary industry and restricting the development of the tertiary industry.In addition,the audit is beneficial for enterprise entry,but not conducive to technological innovation,and has no significant impact on foreign direct investment.This conclusion fills a gap in the existing research and provides valuable insights for policymakers. 展开更多

This paper considers accounting regulation research from a structuration and cultural perspective. Therefore, accounting regulation research spans over three spheres of enquiry: (1) an accounting focus of standard-setting; (2) a cultural analysis in an empirical context; and (3) the use of a research methodology drawn from Anthony Giddens' structuration theory. In such approach, accounting regulation research analyzes the accounting regulation actors drawing upon the cultures in their standard-setting actions and interactions, referring to Giddens' three structural properties of meaning, power, and morality. The integration of these three spheres of enquiry is not entirely original. A few prior studies have similar combinations: Although they stress the uses and consequences of accounting systems in producing and reproducing organizational culture and negotiating meaning at the organizational level, this paper chooses the research approach of contextual analysis of accounting systems at more macro-societal and cultural levels. This different research interest and design provides this paper with its distinguishable characteristic from the prior similar studies. 展开更多

According to the related data of A-share listed companies in 2009-2013,through extension model based on Basu's surplus - the stock return rate model ,this paper studies that the debt maturity structure influences on accounting conservatism. The empirical study finds that the amount of debt affects significantly the prudence,that is,the greater the amount of the debt contract con- cluded, the stronger role of accounting conservatism is ; Debt maturity have significant relationship with accounting conservatism. For the shorter debt maturity, the enterprise is easier to choose more prudent accounting policy, and when the period is longer, accounting conservatism is relatively weaker. 展开更多

Debates on shareholder structure and discretionary management of accounting results have carried forward controversial results. This study is intended to analyze within the Cameroonian context the impact of shareholder structure on the management of accounting results in enterprises. More specifically, its objective is to analyze the impact of shareholder structure on the adjustment of regulating discretionary accounting variables. A panel of enterprises is constituted over the periods 2013, 2014, and 2015 in Cameroon. The modeling of regulating discretionary accounting variables has been carried out according to the model of Jones (1991). The different results obtained show that the degree of concentration of the capital seems not to dissuade the management of result per long-term positions. Foreign ownership and state property stimulate management by regulating discretionary accounting variables. 展开更多

One of the most striking phenomena in recent years has been the increasing proportion of women in the labour force, enabling women in many fields to use their potential and to achieve economic independence. So the gender structure analysis becomes more and more important to society and economic development. Accounting research lacks the study of gender issues. This paper intends to summarize the gender structure of accounting profession in China, and aims to explore the critical factors such as economic system of government, traditional characteristics of women, glass ceiling and psychological factors which take a great influence on the gender structure of accounting profession. A conclusion can be made that the proportion of women participation in accounting profession is higher than men, but the majority of senior accounting professionals in China are still men. 展开更多

Taking a microwave product as an example, a system of integrated assembly structure design is presented. Getting design constraints from the upstream design section through product data management(PDM), the system generates the assembly scheme using the case? based method, then assigns the design requirements into each component of the assembly. The detail design for each component can be performed under these design constraints. In order to practise concurrent design, the system sends the final design result to the upstream section and downstream section through PDM to achieve information sharing and integration. 展开更多

First, the high-rise building structure design process is divided into three relevant steps, that is, scheme generation and creation, performance evaluation, and scheme optimization. Then with the application of relational database, the case database of high-rise structures is constructed, the structure form-selection designing methods such as the smart algorithm based on CBR, DM, FINS, NN and GA is presented, and the original forms system of this method and its general structure are given. CBR and DM are used to generate scheme candidates; FINS and NN to evaluate and optimize the scheme performance; GA to create new structure forms. Finally, the application cases are presented, whose results fit in with the real project. It proves by combining and using the expert intelligence, algorithm intelligence and machine intelligence that this method makes good use of not only the engineering project knowledge and expertise but also much deeper knowledge contained in various engineering cases. In other words, it is because the form selection has a strong background support of vast real cases that its results prove more reliable and more acceptable. So the introduction of this method provides an effective approach to improving the quality, efficiency, automatic and smart level of high-rise structures form selection design. 展开更多

This paper investigated the relationship between demographic structure and international capital flows with panel data of 190 countries over the past 60 years' and projection data for the 21st century. As found, from a global perspective, the current account balance (CAB) is negatively related to the dependency ratio, and orresponding to continuous change, international eapital flows tend to move from "adult countries" to "aged or young countries." Since the middle of the 20th century, the U.S., Europe, Japan, China, Southeast Asia, Central Asia, South Asia, West Asia and Africa took turns in exporting capital to other countries. In the 2lst century, Europe, the U.S., Australia and Singapore will keep importing capital, while China in the 2030s, and Southeast Asia in the 2050s will in turn become the main capital importers. Given the demographic structure of China and the world, the future pattern of the international capital flows requires more serious concern and responses. 展开更多

Bradshaw, et al. (2004), Gelos & WEI (2005) stated that financial reporting quality is fundamental for investors and it affects international capital movements. Following Schipper & Vicent (2003), the authors estimated accounting quality by abnormal accruals and earnings persistence. The authors' contribution consists of investigating a huge number of firms from 17 European countries using unbalanced panel data. The authors found evidence that economic conditions affect accounting quality: big firms and those with high current earnings exhibit better financial information. These results are robust because they do not depend on the accounting quality proxy, even when the authors estimated regression with economical and financial factors alone or together. Financial performance does not seem to affect accounting quality. However, this relation is not linear because in high leveraged firms, the capital structure becomes determinant. 展开更多
