The Impact

Recently, many mountain disasters caused by natural phenomena, such as typhoons and heavy rains, have struck Japan, where check dams are used as important disaster prevention structures. Meanwhile, increased timber use in Japan is expected to revitalize regional economies, thus drawing attention to the use of timber in check dams. However, comparisons between timber and concrete check dams, in terms of their impact on the regional economy, have been overlooked in previous studies. Therefore, targeting Akita Prefecture in Japan, we evaluated quantitatively the respective regional economic impact of timber and concrete check dam construction through an input–output analysis. An extended input–output table was developed based on the revenue and expenditure data obtained from interviews with check dam construction companies. The construction cost and amount of sediment runoff prevention of a concrete check dam was unified with those of a timber check dam to evaluate their respective economic impact. In both cases, the impact of timber check dam construction was about 12 to 13% larger. In brief, timber check dam construction was found to have a more positive impact on the regional economy than concrete check dam construction. However, with the regional self-sufficiency ratio of the lumber and wood products sector at less than 20%, or the lumber price at 60% of its current price, the economic impact of constructing a timber check dam becomes smaller than that of a concrete check dam. In other words, it is important to harvest, process, and use timber regionally to contribute to the regional economy. Specifically, using timber that is processed, rather than simply harvested, in the region has a larger economic impact on the region. Additionally, in timber check dam construction, procuring inexpensive timber and reducing construction costs may be a trade-off for revitalizing the regional economy.

Regional Economic Impacts

The regional economic impacts of the construction of timber and concrete check dams in Akita prefecture, Japan, were compared. When functions are appropriately unified, a concrete check dam is cheaper to build than a timber one; the difference in construction costs can be used by the government to issue premium vouchers as a regional promotion measure. To evaluate the effect of this, we extended the latest input–output table for Akita Prefecture to include timber and concrete check dam construction sectors. Concrete check dam construction with premium-voucher issuance had a total effect of 46,064,000 yen (economic impact ratio: 1.49; increased employment: 4.68 people). It also had an indirect economic impact on the plywood sector, since plywood was used as formwork, and issuing premium vouchers had a ripple effect on many industries in the region. However, timber check-dam construction had a total effect of 57,706,000 yen (economic impact ratio: 1.86; increased employment: 5.11 people) and a larger effect on the timber, logs, and silviculture sectors. Therefore, despite higher initial costs, timber check dam construction has the greater economic and employment impact on a region through its large ripple effects on the forestry and wood industries.

The Impact

Check dams play an irreplaceable role in soil and water conservation in the Chinese Loess Plateau region. However, there are few analyses on the connection between check dams and the downstream channel and the impact on structural connectivity and sediment interception efficiency. Based on a field survey, this study classified the connection mode between check dams and the downstream channel, and the actual control area percentage by discharge canal in dam land was used to quantitatively evaluate the degree of the structural connectivity of sediment between the check dam and the downstream channel. The analysis results show that the connection mode can be divided into eleven categories with different structural connectivity. The different connection modes and its combination mode of check dams and downstream channels in dam systems have a large difference, and the structural connectivity of the dam system is less than or equal to that of the sum of single check dams in a watershed. The degree of structural connectivity of a dam system will be greatly reduced if there is a main control check dam with no discharge canal in the lower reaches of the watershed. Compared with a single check dam, the structural connectivity of a dam system is reduced by 0–42.38%, with an average of 11.18%. According to the difference in connection mode and structural connectivity of check dams and dam systems in the four typical small watersheds, the optimization methods for connection mode in series, parallel and hybrid dam systems were proposed. The research results can provide a reference for the impact of a check dam on the sediment connectivity and the sediment interception efficiency in a watershed and can also guide the layout of a dam system and the arrangement of drainage facilities.

While the study of the regional economy and its factors has been well-researched, relatively less is known on the issues for the digital economy sectors affecting the regional economy. Therefore, the aims of this paper are: to investigate the regional economic impact caused by digital economy sectors; to analyze the multiplier effect of these sectors on the output, income, and employment; and to calculate the economic impact of additional investment in the digital economy sectors. The study focuses on the region of East Java Province, Indonesia. The method used in this study is the input-output analysis (13 x 13 aggregation), which generates transaction of goods and services at a certain time. This study uses data from the Central Bureau of Statistics, Input-Output Table of East Java Province year 2015, which  includes 110 economic sectors, which are then grouped into digital related and non-digital related sectors. The result indicates that digital economy sectors have both backward and forward linkages to other sectors in the region. Further finding shows that digital related manufacturing sector has the highest multiplier effect on the output, income, and employment. While investment injection on the digital economy sectors, based on the analysis, will make better disruption on East Java economy. The government of the region should put an emphasis to attract more investment in the digital economy sectors.

Abstract The rapid development of e-commerce has greatly promoted the development of modern logistics. The application level of e-commerce and the application status of modern logistics largely determine the development of a regional economic structure. Under such circumstances, it is particularly important to comprehensively strengthen the research on the impact of e-commerce and modern logistics on the network regional economy. China is as one of the most active regions over the world. Therefore, in this paper, we take the network regional economic as the research object. Firstly, we obtain relevant regional logistics nodes and e-commerce information through wireless networks. Secondly, based on information acquisition, we propose an empirical analysis of the development status of the logistics industry and e-commerce, and we also explain their contributions to regional economic growth. Finally, this paper proposes countermeasures to further increase the contribution of logistics and e-commerce to economic growth. This will provide a reference for building a regionally coordinated logistics e-commerce system and realizing regional economic integration.

Abstract This article combines the analysis of regional economics, the constant-market-share analysis and the input-output analysis in order to assess the impact of export growth on the main economic variables of a regional economy. The model is first tested for a regional economy by breaking up export growth rates for manufactured products into its various effects. The dynamism of the trade zone to which the regional economy belongs, the production biases on the pattern of trade flows and the cost competitiveness of the economy are then estimated. It is assumed that these estimates reflect the relative importance of the structural and exogenous factors relative to the cyclical and endogenous factors on export performance. The general equilibrium implications of the estimates in terms of direct and indirect employment effects are thus spelled out by the use of available input-output data. The results indicate that Quebec's export performance is not hindered by the geographical pattern of export flows nor by the product-mix of its exports. However, the indicator of cost competitiveness indicates a slight deterioration on foreign markets.

This study evaluated the economic impact of hunting on the regional economy of South Africa’s Limpopo Province. Data on biltong hunting was derived from a national survey conducted in 2009 and data on trophy hunting from the Professional Hunting Association of South Africa (PHASA). Using the input-output (social accounting matrix) and multiplier analyses, we found that the direct economic impact of hunting in the regional economy of the Limpopo Province, as a result of increased expenditure, exceeded R669 million (US$83.6 million). This direct impact resulted in a total economic impact in the order of R1.2 billion (US$150 million) and consequently in a multiplier effect of 1.76. With regard to employment, we estimated that some 8 382 jobs, in addition to those of the employees directly involved, may be dependent upon hunting in the province, which supports the notion that this is a viable and important sector of the tourism industry.
