нашлось вот такое определение в гугле:
Capture rate – скорость захвата: скорость продажи или сдачи в аренду объектов недвижимости относительно скорости продажи или сдачи в аренду всех других объектов на рынке.
но "скорость захвата" как-то чересчур...
есть ли еще варианты?

и на англ.
1) Business Dictionary: Capture Rate
The portion of total sales in the real estate market that are sold by one entity or one project.
2) Capture Rate refers to the ability at which properties are able to be sold or leased in an area.

и мой контекст:
The "capture rate" estimates the portion of tourism spending that shows up as direct sales in a region's economy.

заранее признательна за помощь.

у меня в тексте встречается только один раз в таком контексте (тж. приведен выше):
The "capture rate" estimates the portion of tourism spending that shows up as direct sales in a region's economy.

боюсь, что данные варианты тут не совсем ложатся.... (
вот весь абзац (даже весь пункт статьи (речь идет о Estimating Economic Impacts of Tourism)):

Impact measures: spending, sales, income, jobs, tax receipts

The preferred impact measures are income or value added. The income to the region is reflected in the wages, salaries, rents and profits generated by tourist spending. Value added also the revenues to local government units from taxes. Economists generally use the "value added" by the region's economy as the preferred measure for assessing the contribution of a given industry or activity to a region's economy. Value added is basically the income and indirect business taxes generated by the activity. Tourist spending can yield a distorted picture of tourism's impacts, particularly when tourists are buying goods that are not made in the local area. In these cases only the retail margins on these goods show up as direct sales in the local area and contribute to regional income. The "capture rate" estimates the portion of tourism spending that shows up as direct sales in a region's economy. Although there is great interest in tourism's employment effects, job estimates can be misleading given the large number of part time and seasonal jobs associated with tourism in many areas. All jobs are not "equal" making aggregate estimates or comparisons across regions and industries problematic. Income and value added are relatively clear measures of impact that can be directly compared across industries and regions with quite distinct types of tourism and economic activity.

спасибо огромное, не сочтите за труд еще что-нибудь посоветовать :)
