With the gradual deepening of reform and opening up and the socialist market economy is growing, the various aspects of the statistical environment, objects, and statistical needs a huge change, statistical work and national accounts work in the new situation facing many new problems and challenges. First, the economic component of economic decision-making body is increasingly diverse economic structure and the factors affecting the economic development of increasingly complex. Therefore, macroeconomic management department of national accounts data reflect the status of the national economy increasingly dependent on high, and then put forward higher requirements for national accounts. Secondly, with the gradual improvement of the market economy system, businesses and households began to have the operation and decision-making autonomy, while improvement in the economic strength, risk awareness are constantly enhanced, so increasingly need to understand and master the reaction the health of the national economy the national economy, in order to make the right investment and operating decisions to get the maximum benefit, this new national accounts. Finally, in the context of global economic integration, the rise of China's rapid economic development and international influence, the international community is increasingly concerned about the health of China's national economy, requires the Chinese government to provide more accurately reflect the Chinese nationals economic health, national accounts data, which requires us to consider how to improve our national accounting standards under the conditions of economic globalization objectively. Therefore, in the face of the new situation at home and abroad, we must pay attention to and perfect the system of national accounts, regional GDP accounting is a vital link in the entire system of national accounts, so, how to improve the system of regional GDP accounting to solve data convergence problem is an unavoidable issue of China's statistical work. In the entire system of national accounts, regional GDP reflects the level of economic development of a region to quantify the health of the regional economy. Regional GDP from one to reflect the results of the work of the local government, in China in recent years the region's GDP indicators incorporated into which the government evaluation system. As a result, while promoting effective growth also appeared related issues. For example, the region total sum is much higher than the national data on total, and the gap is growing. Total gap of countries and regions in the first three quarters of 2009 reached 2.475842 trillion yuan, accounting for 11.4% of the country's total GDP. Such a large data gap, to attract the eyes of the concerns of the community. People not only questioned the data itself, but also questioned the accounting methods. Therefore, the problem of regional GDP accounting and data convergence not only cutting-edge issues in the theoretical study of the national accounts, the hot issues of common concern to the community. Study of this issue will enrich and improve the existing regional GDP accounting theory, while also trying to solve the practical problems that exist in the regional GDP accounting to provide scientific and effective way. This article is based on its own national conditions, firmly grasp the key issues in the regional GDP accounting started a comprehensive discussion. Based on this, the discussion will be divided into seven parts. The first part is the Introduction to the article, mainly on the topics of background papers and topics of theoretical and practical significance, domestic and international issues related to Research Overview dissertation ideas, content and research methods at the same time given the papers innovations. The second part is part of the basic theory of the entire thesis, introduced the concept of the region's GDP, accounting scope, principles and methods, and previous regional GDP accounting and data convergence theory to summarize and generalize, China and other countries of the region GDP accounting and data convergence problem solution. Summarize the experience of countries in addressing the problems of the region's GDP and data convergence and weaknesses based on the difficulty in GDP accounting of the entire region and its data convergence problems, and these problems are summarized as the problem of regional GDP accounting model, the special problems of the region's GDP. data convergence issues of regional and inter-country, regional GDP historical data convergence problem, after the text analysis and resolved. The third part of the existing problems in China these modalities, and further tap the Chinese regional GDP accounting mode from the basis of the statistical system, accounting methods, and data convergence, evaluation system, and pointed out that the regional GDP accounting mode special problems of trans-regional economic activity, economic activity and regions of the central government establishments accounting of economic transactions, the difficulties caused to the regional GDP accounting, and is given to solve difficult ideas. Finally, this chapter from a regional GDP accounting department functions, data sources and methods, data quality assessment and control angle improving existing GDP accounting method. The fourth part is the third part of the basis to further examine the question of convergence between regions and countries. Data gap between regions and countries was expanded year by year trend, and caused such a huge gap for many reasons, including accounting classification system defects, the quality of basic statistics, statistical system gap, the current assessment system of regional GDP accounting method statistical management system. Analysis related causes at the same time, this chapter describes the four kinds of methods to solve regional and inter-country data convergence, ie the indicators control system to improve the net outflow in accounting methods, top-down regional GDP accounting methods and the use of investment in production a table constraints to control the region's GDP accounting method, the advantages and disadvantages of the various methods, and choose from a regional GDP accounting method suitable for China's national conditions, in order to achieve the purpose of the settlement of regional and inter-country data convergence problem. Through comparative analysis, the final choice of the \The method of national GDP, split to the region. The fifth part of the quarterly data and annual data of the study area the problem of convergence. In general, most of the regions and countries as well as during the annual national accounts quarterly accounts. Most of the annual accounts for the direct calculation is based on the underlying data, and quarterly accounting due to the the indicators less time-sensitive and strong, take more extrapolation method. Annual accounting data sources is a comprehensive survey and census the basis of data of the quarter is generally achieved through a sample survey, the annual survey coverage, fewer indicators. Quarterly and annual accounting based on the basis of data and different methods of accounting, in the same year, the quarter, and are often not equal to the annual data. In theory, the two should be equal. To solve this problem, most countries using data convergence model (Benchmarking), annual data as a benchmark, quarterly and annual equal, that is, the so-called annual benchmarking for quarterly data. This convergence will lead to the quarterly time series \Currently, the regional quarterly and annual data convergence method used in China there are also the \This chapter recommends using the Denton proportion of convergence convergence of current price quarterly data, in order to solve this problem, and at the same time, improving the constant price quarterly data convergence method. The sixth part of the routine annual economic census annual regional GDP data convergence problem. The region's GDP annual accounting of the economic census data is based on a comprehensive survey accounting, and conventional statistical annual regional GDP accounting data information and projections data, according to the department reported that non-comprehensive survey data, and in the formulation of accounting methods there are some differences, will inevitably lead to the difference between the annual regional GDP data connotation of routine annual and economic censuses. China in dealing with the issues of economic census data with historical data does not converge, usually using the interpolation method, the trend away from the poor and the least squares method and approach, but there is the trend of stability problems. To solve this problem, this chapter improvement the conventional statistical annual regional GDP data and the economic census year data convergence method, at the same time, the trend, set test trend indicators proved that the improved method of rationality. Part VII is the end of the article, the main problem for the previously discussed to reach appropriate conclusions, and propose the corresponding countermeasures and suggestions based on these conclusions, available to decision makers and learn. Overall, the region's GDP accounted for according to the established procedure, the regional GDP accounting to consider the impact of external factors and pay attention to the special problems of the regional GDP accounting approach, choose the appropriate methods to obtain reliable data. And data convergence problems can be drawn The reasons for the gap between regional and national GDP data and solve the problem of regional GDP data convergence, and pay attention to improve the basic statistical system, strengthening statistical coordination and improve data dissemination process. In contrast to the existing literature, this article, whether from the the topic conception, research methods or ultimately solve the problem of thinking, there are some new ideas. And to some extent, to provide a reference for study after.
